dorsal; lateral line nearly straight, with about 80 scales. Entire upper 

 parts of head and body, and sides nearly to level of base of pectorals, 

 dark olivaceous; under parts abruptly whitish or yellowish in alcohol; a 

 dark spot in upper part of axil; dorsal and caudal dark; pectorals dark 

 on inner surface; ventral s and anal plain. From Chasmistes stomias this 

 species is readily distinguished by its larger head, larger, more oblique 

 mouth, less prominent snout, and very small fins. The differences in the 

 fins are very great, particularly in the ventrals. It differs from C. brevi- 

 rostris, as characterized by Dr. Gilbert, in its much larger, more oblique 

 mouth, the absence of papilla) on the lips, and shorter fins. Length 2 feet. 

 Upper Klamath Lake, Oregon. Klamath Indian name " Tswani." (Named 

 for the late Prof. Edward Drinker Cope, who wrote the first paper on the 

 fishes of Upper Klamath Lake. )

Head3J; depth 4* ; eye less than 5; snout about 4; interorbital 3. D. 

 Ill, 7; A. Ill, 6; P. 17; V. 9; scales 84 or 85, 18 or 19. Body stouter than 

 in A. lacustris, head shorter, lateral line more decurved and nearer ventral 

 line at middle of body, and scales more numerous. Mouth very oblique, 

 lower jaw not projecting, maxillary not quite reaching vertical at anterior 

 edge of eye. Teeth 4-4, hooked, and with narrow grinding surface. 

 Origin of dorsal in advance of ventrals, equally distant between base of 

 caudal and middle of eye ; height of dorsal twice its base. Ventrals not 

 reaching anal fin by an eye's diameter; caudal deeply notched. A dark 

 gray longitudinal band with metallic luster extending from opercle to 

 caudal fin, lying chieily above lateral line ; color otherwise plain. Length 

 5 inches. Lake P^tzcuaro, Mexico. (Steindachner.)

This species differs from P. oregonensis principally in the larger size of 

 the scales above the lateral line, the smaller number of rays in the dorsal 

 fin, and the lighter and slenderer pharyngeal bones. Head 3 to 3 in 

 length; depth 5 to 5 A; eye 3| to 4 in head; scales 13 to 16 above lateral
