the National Marine Fisheries Service, Colin Lau^ 

 subsampled trawl catches northwest of Unalaska 

 Island on the Japanese fishing vessels Tomi Maru 

 No. 53 and Eikyu Maru No. 12. Lau often noticed a 

 cottidlike fish that he was unable to identify with 

 certainty. Two specimens of this fish, which he 

 preserved, were accessed into the University of 

 Washington fish collection and later identified by 

 the authors as P. phrictus. Collection data for the 

 two specimens (UW 20762 and 20763) and for two 

 pelagicjuveniles (OSUO 2437 and 2438), obtained 

 in an opening-closing midwater trawl off Oregon 

 (Pearcy et al. 1977), are given in Table 1.

Confirmation of the identity of these four speci- 

 mens was made by comparisons with the meristic 

 and morphometric characters used in the original 

 description (Table 2). Methods for counting and 

 measuring are as in Hubbs and Lagler (1964); 

 measurements were taken to the nearest 0.1 mm 

 with dial calipers; unpaired fin rays and vertebrae 

 were counted on radiographs. These specimens 

 were slightly different from those previously 

 available. The larger specimen from the Bering 

 Sea (UW 20763) has an additional caudal vertebra 

 that may have resulted from development in 

 colder waters. The two juveniles from off Oregon 

 have relatively larger heads than reported 

 previously — evidence of the allometry described 

 by Stein and Bond (1978).
