Inspection of a recent collection of small mammals resulting from field work in Guatemala provided the impetus for a re-evaluation of one member of that group, Goodwin’s small-eared shrew, Cryptotis goodwini Jackson, 1933. On the basis of the results of that study, three new species of small-eared shrews are described from (1) disturbed cloud forest on Cerro Cucurucho, Sacatepéquez Department, Guatemala; (2) highlands east of Mata- quescuintla, Jalapa Department, Guatemala; and (3) Cerro Montecristo, a massif at the mutual borders of northern El Salvador, eastern Guatemala, and western Honduras. The new species are most similar morphologically to the Guatemalan endemic species C. goodwini and C. mam Woodman, 2010, from which they are distinguished by a variety of external and cranial characters. Recognition of the three new species more narrowly defines the distribution ofC. goodwini (sensu stricto), which is now known only from portions of the western Sierra Madre of Guatemala. Key words: biodiversity, Central America, cloud forest, conservation, locomotor adaptation, morphology, Neotropics Resumen Las musarañas de orejas pequeñas (Eulipotyphla: Soricidae: Cryptotis Pomel, 1848) del grupo Cryptotis goldmani es un clado de especies semifosoriales distribuidas de manera discontinua en las tierras altas húmedas desde el centro de México hasta el oeste de Panamá. La inspección de una colección reciente de pequeños mamíferos que resultó del trabajo de campo en Guatemala proporcionó el ímpetu para una reevaluación de un miembro de ese grupo, la musaraña de orejas pequeñas de Goodwin, Cryptotis goodwini Jackson, 1933. Sobre la base de los resultados de ese estudio, se describen tres nuevas especies de musarañas a partir de (1) bosque nuboso perturbado de Cerro Cucurucho, Departamento de Sacatepéquez, Guatemala; (2) tierras altas al este de Mata- quescuintla, Departamento de Jalapa, Guatemala; y (3) Cerro Montecristo, un macizo en las fronteras mutuas de El Salvador, Guatemala, y Honduras. Las nuevas especies son más similares morfológicamente a las endémicas guatemaltecas C. goodwini y C. mam Woodman, 2010, de las cuales se distinguen por una variedad de caracteres externos y craneales. El reconocimiento de las tres nuevas especies define más estrechamente la distribución de C. goodwini (sensu stricto), que ahora se conoce solo en partes de la Sierra Madre occidental de Guatemala.

Here we add a third species, also from Kenya, based on a specimen from the eri- caceous zone of the eastern slopes of Mt. Elgon. Although this species further aligns Mt.

The aim was to study the relationships at higher taxonomic levels within this family, and in particular the position of difficult clades such as Anourosorex and Myosorex. The data confirmed two monophyletic subfamilies, Soric- inae and Crocidurinae. In the former, the tribes Anourosoricini, Blarinini, Nectogalini, Notiosoricini, and Soricini were supported. The latter was formed by the tribes Myosoricini and Crocidurini. The genus Suncus appeared to be paraphyletic and included Sylvisorex.We further suggest a biogeographical hypothesis, which shows that North America was colonized by three independent lineages of Soricinae during middle Miocene. Our hypothesis is congruent with the first fossil records for these taxa. Using molecular dating, the first exchang- es between Africa and Eurasia occurred during the middle Miocene. The last one took place in the Late Miocene, with the dispersion of the genus Crocidura through the old world.

    Dental Anomalies in Three Species of Shrews from Indiana Thomas W. French* Department of Life Sciences Indiana State University Terre Haute, Indiana 47809 Introduction Dental anomalies in shrews are not common. Hall (1940) found no cases of miss- ing or extra teeth in 1,837 specimens of North American shrews and Jackson (1928) reported only 5 specimens (0.05%) with dental anomalies out of 10,431 Sorex and Microsorex examined. Information on dental anomalies in shrews has been best sum- marized by Choate (1968). Most reported dental anomalies result from a reduction in the number of upper, and to a lesser extent, lower unicuspid teeth (12, 13, C, P2, P3, 13, and c of Choate 1968). No case of genetically deleted molariforms or first incisors has been reported in shrews. Subnumerary dentitions have been reported from Sorex araneus (Reinwaldt 1961), S. cinereus ohionensis (Bole and Moulthrop 1942), 5. minutus (Reinwaldt 1961), S. obscurus longicauda (Jackson 1928), S. tundrensis (Pruitt 1957), Blarina brevicauda and B. b. carolinensis (= B. carolinensis) (Choate 1968), B. adamsi (from the upper Pliocene— Hibbard 1953), Cryptotis goodwini, C. mexicana, C. nigrescens, and C. parva (Choate 1970), and Microsorex hoyi (Jackson 1928). Supernumerary dental formulas have resulted most often from extra upper unicuspids and have been reported from 1 Sorex o. obscurus (Jackson 1928), 1 S. s. saussurei (Hooper 1946), 3 Blarina carolinensis (Choate 1968), 1 Crocidura cyanea, 2 C. hirta (Meester 1953), and 3 C. marquensis (Dippenaar 1978). Extra unicuspids in the lower jaw have been reported only from Blarina brevicauda (Hibbard 1953). Supernumerary molariform teeth in shrews are especially scarce.

The new species, Crocidura narcondamica sp. nov. is medium-sized and has a distinct external morphology (darker-grey dense fur with a thick and darker tail) and craniodental (braincase is rounded and elevated with weak lambdoidal ridges) characters in comparison with other close congeners. This description illuminates the rst discovery of soricid fauna (shrew) from this volcanic island and a total of 12 Crocidura species catalogued in the Indian checklist of mammals. The newly discovered species maintained sucient genetic distances (12% to 16.6%) with other Crocidura species known from the Indian mainland, Andaman and Nicobar Archipelago, and Myanmar.

While the most advanced technological means to photograph and reproduce this document have been used, the quality s heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand rrarkings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

Carraway1 ABSTRACT.—Examination of published records, and morphometric and morphologic analyses of 3398 museum speci- mens, revealed that 4 genera including 30 monotypic and 5 polytypic species of shrews (Soricidae) occur in Mexico. Of these, 2 new species were named and 2 subspecies were heretofore unrecognized, 3 were reclassified, and 1 was ele- vated to species level. Cryptotis goldmani machetes, previously subsumed into C. g. goldmani, was reelevated based on ventral pelage color. Sorex veraepacis mutabilis contained 2 morphotypes, 1 of which matched that of the holotype; how- ever, the 2nd morphotype not only did not match that of the subspecific holotype, but also has a sympatric distribution.
