pressed and its length about 3/5 its width at front of eye. 

 Eye small, largely lateral, ellipsoid, and hind edge well before 

 center in head length. ]\louth broad, lower jaw well pro- 

 truding in front. Teeth line, in villiform bands in jaws. Max- 

 illary barbel reaches pectoral origin, nasal barbel 2 1/2 times 

 eye length, outer mental barbel i 3/4 to pectoral origin and in- 

 ner 2 1/2 in same space. Upper surface of head and interorbi- 

 tal rather convexly elevated. Space unossitied between end of 

 occipital process and front of dorsal plate slightly greater than 

 horizontal eye-diameter. Gill-rakers 5 + 8, short points, longest 

 about 3/4 of eye. Humeral process finely and rather obsoletely 

 rugose. Skin smooth. Dorsal inserted midway between tip of 

 lower jaw and first fourth in adipose fin length, and depressed 

 fin about half way to adipose fin. Dorsal spine slender, edges 

 smooth, about as long as snovit. Adipose fin very slightly 

 shorter than dorsal spine. Anal inserted a little nearer caudal 

 base than pectoral origin. Caudal truncate. Pectoral reaches 

 I 3/4 to ventral, spine short, smooth and bvtt a trifle longer 

 than snout. Ventral inserted about midway between caudal 

 base and snout tip, fin reaches anal. 



Color in alcohol largely uniform brownish, belly and under 

 surface of head faded whitish. Iris grayish. Barbels all more 

 or less brownish. Fins also brownish.
