OESCRIPTIOrV OF A NEW SPECIES OF URANIDEA (IJKAIVIB>EA 

 KfilOTMEA) FROri SPOKAIVE RIVEK, ^VA.SHIIVOTOIV TERRITORY. 



By ROSA SMITH. 



Head 3 (3f); depth 4^ (oi); length (30737) 3 iuches. D. YIII-IG; A. 

 11; V. I, 4; Br. 0. 



Subgenus Cottopsis Girard. 



Body of the usual form in the genus, widest anteriorly, gradually 

 tapering to the tail, the greatest width just behind head, 1} in greatest 

 depth of body. Head wide, depressed, its depth half its width. Mouth 

 moderate, maxillary reaching the vertical of posterior margin of pupil. 

 Eye moderate, 1^ in snout. Snout 3} in head, more pointed ami the 

 head broader than in U. gulosa or U. aspera. Interorbital space rather 

 narrow, 2 in eye, slightly concave. 



Yilliform teeth on jaws and vomer, about as in U. aspera, the pala- 

 tine teeth forming a broader and much longer baud than in the latter 

 species. 



Opercular spines nearly as in U. aspera; a sharp spine at the angle 

 of preopercle directo.l upward and backward, below which are two 

 small and very blunt ones. A single spine directed forward at the 

 inferior angle of opercle. 



Skin of the head smooth to the touch, but there are numerous very 

 minute tubercles on the nose, interocular width, and vertex. An 

 a]>pearance of prickles is observed on the space between occiput and 

 origin of dorsal, but no roughness can be felt. Conspicuous prickles 

 extend from the scapula and origin of dorsal fin almost to base of 

 caudal, and below the lateral line a distance equaling the interorbital 

 space; these prickles more prominent than in U. aspera. The lower 

 surface of head, the abdominal region, and base of anal are smooth 

 and without any trace of warts or prickles. 



Isthmus rather broad, the gill-membranes not forming a fold across 

 it. First dorsal low, its margin convex; fourth and fifth spines highest, 

 about 4 in head. First ray of soft dorsal equaling highest part of 

 spinous, increasing to the third, which is 2\ in head, the outline nearly 

 straight from third to fifteenth rays. Caudal subtruucate. Anal sim- 

 ilar to soft dorsal, its last ray inserted opposite insertion of fourteenth 

 dorsal ray, the free tips, not extending quite as far as those of dorsal. 

 Ventrals not reaching vent, 2 in head. Pectoral attaining third ray of 

 soft dorsal and barely to beginning of anal. 



Caudal peduncle nearly 4 in greatest depth. In young examples the 

 opercular spines and dermal prickles are more conspicuous than in the 

 adult. 



Color, in spirits, olivaceous with blackish markings. Upper part of 

 head dark gray, with a darker area on occiput. Two blackish spots at
