This species differs from Pallasina barbatus in having 

 a much shorter barbel on chin, in having two median 

 plates in front of ventrals in place of three, and in having 

 the plates between the median and lateral plates much 

 smaller and less regular in arrangement. In P. barbatus 

 these plates are about as large as the median plates and 

 always interposed between them and lateral plates, the 

 arrangement being constant. The abdominal ridges are 

 generally closer together in P. aix than in the northern 

 species. 



This species was taken with the seine in great abund- 

 ance in Puget Sound, near Port Ludlow; the largest is 

 nearly five inches in length, the others about three. 



This type has been given the number 5040 on the reg- 

 ister of the collection in the Leland Stanford Jr. Univer- 

 sity Museum.
