Proceedings of the United States National Museum 48 PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. DESCRIPTION OF A NEW SPECIES OF WHITEFISH {Conoonus nelsonii), FROM ALASKA. BY TAKL,ETOi> IB. BEAN, Cvrator of the Department of Fishes in the United States Katioval Museum. Coregonus nelsonii Beau. Htiuip-back whitefish. This ts|)ecie8 is known from Alaska only, occuniujj^ from the Bristol Bay region northward to the extremity of the Territory. This whitefish, which appears to be still undescribed, has long been known from Alaska, bnt it has been confounded with a Siberian spe- cies, C. syrok, from which it is really very different. The Russian name of the species is Korahati ; the Tiuneh tribes of the Yukon call it ''Kolo- huh.'''' Mr. Dall, in the report of the Commissioner of Agriculture for 1870, ])age 38G, speaks of it as a common species, characterized by the strongly arched back and broad tail. He says it is rather bony and inferior in tlavpr, and tliat it is generally tised for dog-feed, except in times of scarcity. This species is related to C. clupeiformis and C. lahradoricuH. From clu- peiformis it may readily be distinguished by its greatly arched and mucli compressed back. The body is oblong and comjjresscd ; the head is one-fifth as long as the fish without the caudal; the maxilla extends to the front margin of the eye, and is about one fourth as long a.s the head ; the gill-rakers are only moderately long, the longest a little more than one-half length of eye, and their number is about 26. The great- est height of the body is a little more than one-fourth of the total length ill the typical example, which is about 14.^ inches long to caudal base. The adipose fin is large and scaled for nearly half its height. The ventrals are a little nearer the tip of the snout than the root of the caudal; they are about as long as the head without the snout. D. 12 ; 12 scales 10—88—10. The type of the species is No. 29903, taken A. ; at Nulato, Alaska, by Mr. E. W. Nelson, to whom the species is dedi- cated in recognition of his important zoological researches in that Ter- ritory. ON THE LITERATURE AND SYSTEMATIC RELATIONS OF THE SACCOPHARYNGOID FISHES. By TEIEODORE OIL.1^ aud JOHIV A. KVDER. About sixty years ago a most remarkable fish was first introduced into scientific literature under the generic name Saccopliarynx. Other examples have been found in the meanwhile, and yet until the present the form has had no established place in the system. Notwithstanding the alleged existence of two specimens in one of the richest ichthyolog- ical collections extant, uiuler the custody of one who has i)rofessed to give the most complete system of fishes, the type has been involve<l in PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 49 Vol. Til, IVo. 4.

The recent discovery of an even more remarkable form in the deep seas of the North Atlantic has directed our attention to the older known species, and by reason of the light reflected by the newly-discovered one, we are enabled to interpret much that was am- biguous and inexplicable in the descriptions of the old ichthyologists. We here give an historical sketch of Saccopharynx and the fishes that have been referred to that genus. I. BIBLIOGRAPHY. 1§24—Description of au extraordinary Fish, resembling the StylephoruB of Shaw.

Mitchill, in the Annals of the Lyceum of Natural History of New York (v. 1, pp. 82-8G), contributed a " description of an extraordinary fish resembling the Stylephorus of iShaw." The fish in question was presented to Dr. Mitchill by Capt. Hector Coffin, and " was taken daring a voyp.ge from Londonderry to New York, in latitude 52 PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 51 N. and longitude 30 W. It was discovered afloat about tweutj" yards from the vessel. A boat was hoisted out for the purpose of raising it. The creature was raised from the water without any resistance, and died in fifteen minutes after being taken on board." " When first seen, the belly was distended, as if blown up to the size of a quart decanter, or the crown of a hat. The stomach contained a fish ten inches long, which, from its sound state, appeared to have been recently swallowed. That fish was not preserved. " The length was six feet ; of which fourteen inches belonged to the body, or the space between the extremity of the upper lip beneath to the vent.

    06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago).

CASTLE Anglo American Corporation of South Africa Advanced Research Fellow in Ichthyology (Published by the J.L.B. Smith Institute of Ichthyology, Rhodes University, Grahamstown, South Africa) Long & Co. (Pty) Limited Printers Port Elizabeth Republic of South Africa 1 AN INDEX AND BIBLIOGRAPHY OF EEL LARVAE by P. H. J. CASTLE’ ABSTRACT A survey o f ichthyological literature from 1758 until the end of 1968 reveals that information on eel larvae {leptocephali) is widely scattered and contained in at least 600 different papers. A synthesis of tlris information, essential for the correlation of larval eels with their adult species, is attempted here as a necessary adjunct to the further development o f systematic studies on adults. About 450 forms of eel larvae have been described, of which nearly 100 have been at least tentatively identified; some 200 have been named as species of die genus Leptocephahis Grono- vius, 1763 (now a rejected name in Zoology), or of other larval genera; the remainder have not been named. Systematic and bibliographic information on these cel larvae is presented togedier with a geographic checklist and a list of myomere numbers in leptocephali. Reports of eel eggs and prelarvae are not included but these may be found in some of the papers listed. The leptocephalous larvae of other groups of fishes are excluded from this index, aldiough references are made to relevant sources of information.

Pectoral fin pres- ent. Scales absent. Lateral line reduced; pores on body absent, replaced by small, dermal papillae; addi- tional papillae on head; some pores around eye and on snout. Colour: black or reddish, without markings. small eye non-occlusible jaws notch Habitat, biology, and fisheries: Cyematids live in midwater at depths of 1 500 to 3 000 m. Little is known of their biology; there is no indication of sexual dimorphism. They are of no importance to fisheries and are sel- dom seen except when brought up by deep-towed midwater trawls. Remarks: Two genera are known, each with a single recognized species. Cyema atrum is the most common and occurs in all oceans. Neocyema erythrosoma Castle, 1978 is known only from the South Atlantic. Several distinct kinds of leptocephali are known, however, indicating that additional species exist.
