just below the lateral line, sometimes their centers are somewhat 

 pigmented; caudal fin barred; anal fin plain whitish to grayish on 

 females. 



Tliis species differs from other cottids in combining the absence of 

 palatine teeth, the arched lateral line, pelvics I, 3, with smooth skin, 

 bluntly rounded preopercular spine, anus just behind pelvic insertion, 

 dorsal rays XI or XII, 22 to 24 ; anal rays 22 to 24. 



Named in reference to the large conical anal papillae and the 

 bluntly rounded preopercular spine.

SIGMISTES SMITHI, new species 



Holotype. — A male specimen 37.5 mm long to base of ra3-s of caudal 

 fin, collected in a beach seine at Igitkin Island (Aleutian Islands), 

 Alaska, August 9, 1937, by Victor B. Scheffer, original number 

 V. B. S. 109, U.S.N.M. no. 105282. Two paratypes were collected 

 along with the holotype, U.S.N.M. no. 105283. 



Descriftion (based on the holotype and paratypes). — The counts 

 and measurements of the holotype are given outside the parentheses 

 and those for the two paratypes, respectively, are enclosed in the 

 parentheses. All measurements are expressed in hundredths of the 

 standard length. The last two soft rays of dorsal and anal fins, 

 often branching from a common base, were counted as one ray.
