The pyloric caeca, as in the other Pacific species, are very numer- 

 ous, and are branched. The center of the anus is placed well in 

 advance of the anal origin, the interspace being about one-half of the 

 distance between the anus and the ventral fin, or one-fifth the post- 

 orbital length of the head. There is a small naked fossa between 

 the ventral fins. 



The dorsal spine is without denticulations. 



The color in alcohol is silvery gray, clearest along the middle of 

 trunk and tail, becoming brownish on'the back, dusky on the opercles 

 and gular membranes, and blackish between the ventrals and the 

 anus.

This species is well distinguished by its blunt, low snout, strong 

 dentition, long barbel, uniform dusky fins, etc. In these diagnostic 

 characters the four paratypes, which are in poor condition, agree 

 with the holotype.
