IrECENT LITEItATUI•E Hellm•yr's 'C•t•logue of Birds of the Americas'.•--The high standard and thoroughnessthat characterizeDr. Hellmayr's earlier volumesin this seriesare fully maintained in the present one which deals with the Neotropical Ploceidae (all introduced), Catamblyrhynchidae and Fringillidae; it concludesthe American Passeriformes.The most difficult groupsare finishedand the end of the series, originallyinitiated by C. B. Cory in 1918,is in sight. The statementin the introductionthat "in a work of this magnitudeit is simply impossibleto investigate everything independently, and the author has to rely largely on the researchesof others" arousesa chordof sympathyin the reviewer,but there is probablyno ornithologistwho is lessdependent on the researchesof others than Dr. HeIlmayr; true, he has not goneinto the speciescovered by the A. O. U. 'Check-list' as thoroughlyas thosenot included,nor are his synonymiesof the species dealt with by Ridgway in part I of Bulletin 50 of the U.S. National Museum as extensive,for the simplereason that lengthy duplicationwould result. The classificationof the Fringillidaeis basedon the arrangementproposed by the late P. P. Sushkin and recognizesfive subfamilies:Richmondeninae, Geospizinae (confinedto the GalapagosArchipelago and CocosIsland), Fringillinae (this sub- family has no normal Americanrepresentative), Carduelinae and Emberizinae. The only improvementthat can be suggestedhere is that the work shouldhave beenbrought up to as late a date as practicablebefore being submitted for publica- tion, and then no further additionsmade of racesnewly describedafter that date. As a casein point, Griseom'sreview of the crossbillsthat appearedin 1937 is only mentionedin a footnote,while at least one name publishedin appearsin full at its proper place. Among the nomenclaturalchanges proposed are the setting up of the genus Periporphyrus Reichenbach for Caryothrausteserythromelas (Gmelin); Acanthis linaria becomesAcanthis flammea on groundof page anteriority and Fringilla pra- ten•is Vieillot replacesAmmodramus australis Maynard as the name of the Eastern GrasshopperSparrow.--J. L. PETERS. Hyde's 'Life History of Henslow's Sparrow. '--This addition2 to studiesof one particular bird, now rapidly on the increase,is the product of three seasons'field work on breedinggrounds in southernMichigan plus whatever could be gleaned from the examinationof numerousspecimens and the literature. A preliminary sectionon distributionand migrationis naturally a compilation. The chiefpoints of interestbrought out are: (1) lhe possibleenlargement of the formerbreeding range with the clearingof the colonialforests, and (2) a center of relative abundancein southernMichigan, Ontario and Ohio. For the benefit of local studentsthere is a useful compilation of distributional data by States.

pitifully thin. For most of it the author is not to blame--Henslow's Sparrow is practically unknown on migration--but the author did have an opportunity to determinethe arrival of the first birds on the breedinggrounds (given for only one year), when the full complementof breeding birdsarrived, and to what degree femaleslagged behind the males. The two last points are not mentionedat all. The chief contributionto knowledgewhich the author makes is in the relatively full sectionsdealing with the nest, eggs, and young. The female alone builds the nest, both sexesfeed the nestlings,the incubation period is astonishinglybrief, as is also the nest life of the young. It is not clear how the sexeswere distinguished with certainty. The author has done a goodiob in compilation,and what he could in three seasons' field work. Twenty years ago this monographwould have been wholly praised. Unfortunately, the techniqueof life-history studiesand the criteria of adequacyare now enormouslyadvanced. Perhapsthe only point at which the author is really open to criticismis his selectionof so supremelydifficult a species. There is practi- cally no discussionof terrritory, very little on courtshipand mating, interestinghints only of possiblepromiscuity in a very loosesocial organization. It would be un- reasonableto expectanswers to all thesequestions in only three seasons'work in one place, with so secretivea little sparrow,that cannot be trapped and banded. Field experienceover many years in every sectionof the breedingrange can alone hope to explain the small total population, the basis for the selectionof dry fields in one place, wet meadowsin another; why a loosecolonial breeding system should prevail in certain parts of the range, and shouldbe unknown in others; where the scattered pairs, erratically enough,almost never return two years in successionto the same meadow. These are questionsof outstandinginterest about Henslow'sSparrow, which someday a life-historystudy will attempt to answer. In the meantime,how- ever, the reviewerfeels strongly that the author shouldbe thanked for what he has been able to find out rather than blamed for gaps which at the moment cannot possiblybe filled.--LuDLow GRISCOM. 'Proceedings' of the Eighth International Ornithological Congress• held at Oxford in 1934, forms an imposing volume containing an unusual number of papers of general interest. The introductory matter consistsof the usual account of the activities, addressesand list of members. Then follow the paperspresented at the congress(arranged in no obvioussequence)---some 67 in all with additional titles of those elsewherepublished. The paperscover a widevariety of subjects. First is a summaryby Meise,of the progressin systematicstudy of birds since 1920, with lists of the new genera and speciesproposed. Others in systematicornithology include an accountof mutation in Lybiusby Salomonsen,on the relation of the Struthionesto dinosaursand to other birds by Lowe and Tucker, classificationof the Anatidaeby Delacour,problems in speciationin Juncoby Miller, genericlimits in the fruit pigeonsby Peters,system- atics of the CrestedGulneafowl by Ghigi, taxonomicproblems in the Bean Geese by Berry, and others. Under generalbiology, the White Stork comesin as usualfor a sharein threepapers by Schiiz,Bouet, and Schenk,respectively, European heron- riesare discussedin Englandand in Italy, Mrs. Nice expoundsterritory and mating in the SongSparrow, and Middletonpresents a summaryof studiesin the fluctuations of Britishgame populations, with indicationsof well-markedcycles in severalspecies.

Interesting conclusionsas to the derivation of lipochromesof birds from plant carotenoidsare given, and it is shownby V51kerthat lutein, a yellow vegetablepig- ment, is the sourceof the yellow lipochromein birds. ProfessorJulian Huxley re- views the old subject of color and its meaning,with new conclusionsand a classifi- cation of these, as for concealment,threat or advertisement,for sexual recognition and display,thus combiningand sifting the views of Bates, Poulton, Hingston and Thayer. Sundry papers of a geographicnature, on birds of such widely separated areas as Asia Minor, South Africa and the Tres Mafias Islands, alternate with otherson homingand migration. A longerpaper on the evidenceoffered by present distribution of birds in support of former land connectionswith Europe or north- easternAsia, by Stegmann,seems to have altogetherignored the now classicpaper of Matthew on 'Climate and Evolution' (1915) wherein a reasonableexplanation is offered. Finally bird protection,oil pollution, avicultureand feedinghabits comein for consideration. Although extendingto over sevenhundred pages,there is no index beyond a list of titles and no list of plates. The volume is handsomelyprinted and under the careful editorshipof Rev. F. C. R. Jourdain,presents much evidenceof painstaking preparation. It is thereforethe more to be regretted that with singularlyfew ex- ceptions,authors have neglectedto give a summary paragraphat the end of their papers, setting forth the gist of their investigations. Few personswill have time enoughat commandto read through the volume with papersin three languages,so that sucha help wouldhave addedgreatly to the utility of the whole.--G. M. ALLES. Morgan's 'Field Book of Animals in Winter' is the latest addition to the well-knownpocket guidebooks on natural history publishedby G. P. Putnam'sSons, and constitutesthe twenty-secondvolume of the series,five of which have dealt with birds. It is written from the standpoint chiefly of a New England naturalist, in answerto the question,"What becomesof our animallife in winter?" For anyone who annuallysurvives our varying winter season,comes to realizethat it requiresa degreeof specializationand adaptationin habits and structure not found amongthe speciesof more equableregions. The openingchapters sketch the devicesof north- ern animalsfor meetingthe physicalconditions of the cold months,and the activities of many animalsat this period;and further considersthe two generalmeans of escape: migration,whether downwardfrom the plants into the earth, from land to water, or to distant regions;and hibernation,whereby many types of both invertebratesand vertebrates passthe inclement period in inactivity. The matter of winter communi- ties and the seasonalchanges that go on in fresh water with consequenteffect on the animal life are conciselyand interestinglyset forth. In fourteenchapters, the several main groupsof freshwaterand land invertebratesare taken up and their wintbr life briefly told, followed by five on the vertebrates. Birds come in for their propor- tionate share, with a chapter on winter bird life, ways of meeting winter, winter flocks,roosting aggregations, winter food, the conditionsof water and shore. The chapter concludeswith a seriesof short descriptionsand characterizationsof the winter birds commonlyfound in the northeasternStates, following the samemethod as in many of the other chapters and there are four colored plates by Peterson illustrating over eighty speciesof winter birds. Other groups are well illustrated from photographsand drawings(including sundry older classicoutlines); there is a helpful bibliography and a good index. Very few errors of type or of fact were noticed(p. 392, Arquatellais misspelled;p. 27, 'EnglishMarmot' shouldbe European Marmot, for this animal is not found in the British Isles).

little book• shouldserve its purposewell and prove a usefuland stimulatingcom- panion to the field naturalist in winter.--G. M. ALLEN. Clements and Shelford's 'Bio-ecology.'--That animal life is dependent, directly or indirectly, on plant life is almost axiomatic;but that the two may be mutuallyinterdependent to a greateror lessdegree, the onereacting either favorably or unfavorablyon the other, has beenless often emphasized. The presentvolume • essaysto correlatethe fieldsof plant ecologyand animalecology, and sincethe term 'ecology'is sooften usedof either alone,the term 'bio-ecology,'in spiteof a seeming redundancy,was coined by ProfessorClements to imply this syntheticaspect. The openingchapter traces the historicaldevelopment of this concept,particu- larly with relationto aquaticcommunities. The plant-animalformation (or 'biome') is the basiccommunity unit and may be thoughtof as a complexorganism. Its componentshave their severalfunctions, life forms,aggregations, population densi- ties and other features,which combineto give a generalcharacter to the whole. The influenceof the community on the habitat, such as that exerted by burrowing animalsor the roots of plants,the interrelationsof the componentorganisms, their relationsto food and shelter,aggregations and competition,are interestinglydis- cussed.There is a valuablereview of the subjectof cycleswhich, it is emphasized, occurin plants as well as in animals,and seemlikely to be determinedby some common basic cause, concerningwhich the authors remark: "The evidence for a solarcycle in the weatherof the globeand in relatedbiological phenomena is nowso strong that this must be regardedas by far the most probableprimary causein- volved." The chapteron migrationmay be to the ornithologistone of the mostinteresting. Its discussionof the causesand methodsof suchmovements is the best summary of the subjectthat the reviewerhas read. That temperatureand its physiological effectsmay be, as Dr. Kendeighhas suggested,one of the primal causes,is well brought out. For while recentinvestigations have shownthat regularsmall incre- ments of light may causegonadal development in birds, this doesnot of necessity inducemigration in spring,and the reverseprocess fails to accountfor the autumnal migration. That the originof bird migrationis to be soughtin the geologicallyrecent ice age, with its advanceand retreat of ice caps,is satisfactorilydisposed of by the later work of Clements,Chaney, and Berry, who find "the assumptionthat the climateduring middle and late Tertiary wasnotably warmer and moreequable and henceattended with little or no zonation far into the arctic regionsis no longer tenable, as the revaluation of the classicfossil floras of North America has shown in particular." As an illustration of the characteristic features of the 'biome' and the interde- pendenceof its constituentsand their relationto climate,there is an interestingchap- ter on the North Americangrassland area followedby chapterson freshwaterand marinecommunities and an excellentbibliography of 36 pages. In the modernstudy of plant and animalrelations ecologists seem to find a needfor many new termsto expressgeneral concepts with greaterprecision. In the presentwork, many of these appear,some for the first time. While this may be necessary,it often makesdifficult reading, where one must keep a finger in a glossary. Ornithologistsseldom find

Sometimesone has an impressionthat ecologyis in dangerof beingoverburdened with suchtechnical terms. This volume is a very welcomesurvey of the generalfield of interrelationshipsof combinedanimal and plant communities,which shouldprove valuablenot only as a manual for the teacher and student of biology in its origlnal sense,but also as a stimulusto the investigationof a still fertile field.--G.

Mrs. Bailey's 'Among the Birds in the Grand Canyon Country'• is in effect a convenient'satchel guide' depictingthe generalfeatures of bird life that the usual tourist may expectto see,besides much more that the casualobserver will missor may find only on a more extendedstay. Only by living in it, campingin it, and repeatedlyvisiting it at differenttimes and seasons,as the authorhas done, may one form a real acquaintancewith this extraordinaryregion and its animal life. In twenty brief chaptersMrs. Bailey takesthe readerfrom the top of the SouthRim down by easystages from zoneto zone till he reachesthe very bottom of the vast abyss. Thenceafter explorationsand digressions,he continuesacross and up to the Kaibab Plateau on the farther side. The familiar or characteristic birds and mam- malsalong the way are charminglywritten of, so the readereasily imagines that he himseifis makingthe transit. The final chapteris by VernonBailey on the remoter cornersof the canyonbottom. The pagesare profuselyillustrated with half-tone cutsof the scenery,the many birds,the deerand squirrels,some of them reproduced from photographs,others from drawingsfrom various sources,many from the author's 'Handbook of Western Birds.' Finally there is an illustrated field key to the males of the commonerbirds the visitor is likely to meet with, followed by a nominal list of 188 birds hitherto recordedfrom the region, and an index. Written in easy descriptivelanguage with abundant illustration, accurate and informative,it is the sort of bookletthat will appealto the increasingnumbers of our citizenswho are learningthe educationaland recreationalvalue of the national parks wherewildlife may be enjoyedundisturbed.--G.
