ART. XXXIII.-REPORT ON THE COLLECTION OF FISHES MADE BY DR. ELLIOTT COUES U. S. A. IN DAKOTA AND MONTANA DURING THE SEASONS OF 1873 AND 1874. BY DAVID S. JORDAN, M. D. [The fishes worked up by Professor Jordan in the present communication represent probably about two-thirds of the collection made during my connection with the United States Northern Boundary Commission, the remainder of the specimens having been lost or mislaid. I am informed, however, that the series submitted to Professor Jordan contains some novelties, rarities, and other specimens of sufficient interest to render publication desirable. I have incorporated a few collector's field-notes with the author's manuscript. The fishes taken in 1873 were secured in the waters of the Red and Mouse Rivers and some of their affluents; those secured in 1874 are from watersheds entirely different both from the last named and from each other, being partly taken from the Milk River and its northern tributaries, and partly from the Saint Mary's River, Chief Mountain Lake, and other headwaters of the Saskatchewan. For articles on other portions of my collections see this Bulletin, this Vol., No. 1, pp. 259-292; No. 2, pp. 481-518; No. 3, pp. 545-661; No. 4, pp. 801-830.—ED.] By some accident, the exact record of the localities of some of the smaller fishes bas been lost or confused, and some of the specimens collected by Dr. Coues have failed to reach the writer, having probably been distributed through the general collection of the National Museum. I therefore add the field record of Dr. Coues, from which the general field of collection can be ascertained. Collector's Memorandum. 1000. Catfish. Red River, near Pembina, Dakota.

Dr. Coues writes me that he obtained a fine specimen of this species at Fort Buford, Dakota. I have not seen it, however. This species seems to be abundant in all the large streams between the Alleghanies and the Rio Grande. West of the Rio Grande Basin, it has not yet been noted. The "Gristle-nosed Fish" from Saint Mary's River, recorded by Dr. Coues, is perhaps Polyodon folium Lac. I have not seen the specimen referred to. Family SILURIDE.

The specific names olivaceus, simp soni, hammondi, and notatus have been given to Channel Cats from the Missouri region, chiefly on account of their "remote habitat"; but the examination of specimens does not show a shade of difference. 1876-Pantosteus virescens COPE, Lieutenant Wheeler's Expl.

Numerous small specimens, from two to seven inches in length, agree ing very well with Professor Cope's description. They all have the peculiar form of mouth, and the semi-cartilaginous maxillary sheath, which the other members of this genus and some of the species of Catostomus possess. The head is very short, forming barely one-fifth the length without caudal. The scales are very small, there being from 95 to 100 in the lateral line. All of these specimens have, however, a small fontanelle, which probably becomes closed with age; otherwise the species is to be referred to Catostomus. Its relations to Catostomus discobolus Cope are very close. Genus CATOSTOMUS Le Sueur. 4.-CATOSTOMUS RETROPINNIS Jordan, sp. nov. This species belongs to the subgenus of typical Catostomus. It is therefore related to C. latipinnis, C. longirostris, and C. tahoensis, and may be briefly characterized as having the body, scales, dorsal and ventral fins of longirostris, with the mouth and lips of latipinnis. Its nearest relations are, I think, with latipinnis, with which species it is compared below. Body long and slender, subterete, compressed behind, the form there. fore essentially that of C. longirostris, the depth contained 53 times in the length. Head large, long, its length contained about four times in the total length without the caudal fin (43 in latipinnis); interorbital space broad and flat, about 2 times in length of head; eye small, high up, and posterior, entirely behind the middle of the head (near the middle in latipinnis); preorbital bone very long, its length about three times its depth (scarcely twice in latipinnis); the snout correspondingly prolonged; fontanelle quite small; mouth very large, formed as in latipinnis, but rather broader and not so long; upper lip pendent, very large, with a broad, free border, with 5 to 8 series of low tubercles, almost obliterated in the type-specimen, on account of the softening of the skin; lower lip very full, its posterior margin reaching to the nostrils (rather farther in latipinnis). Dorsal fin not large, its rays I, 11 (I, 13, in latipinnis); its base about three-fifths the length of the head (five-sixths in latipinnis); its insertion unusually backward, much nearer base of caudal than the tip of the snout (much nearer the snout in latipinnis); caudal fin large, well forked, its rudimentary basal rays not greatly developed; anal fin long and high, reaching base of caudal; ventrals not reaching to vent (to vent in latipinnis); pectoral fins long. Caudal peduncle rather stout and deep, its least depth more than one-third head (less than one-third in latipinnis); its length about two thirds that of head (seven-eighths in latipinnis). In latipinnis, the caudal peduncle is notably long and slender. Scales quite small, about as in longirostris, larger behind, the exposed portion not notably lengthened as in latipinnis; chest with well-developed scales (these rudimentary and imbedded in latipinnis). The type is a large specimen, 163 inches long; a male, as is shown by the presence of tubercles on the anal and caudal fins, a fact confirmed by dissection. In coloration, it is rather dark, with traces of a dusky lateral band, which passes around the snout. This specimen is numbered 21197 on the Register of the National Museum. Another specimen of this species is in the National Museum, from Platte River. It was identified by me as the female of C. latipinnis, the numerous differences in form being supposed to be sexual.
