This species is allied to lateristriga. The barbels are shorter, the pectoral 



spine with much more feeble teeth behind, and the head is more depressed and 



broader. The snout is rounded, the mouth inferior.

These specimens representing the P. transitoria of Ribeiro can scarcely be 

 separated from P. lateristriga. The largest are, however, larger than the largest 

 of the typical P. lateristriga. The left maxillary extends to the end of the ventrals 

 in the four specimens of 6976, in two others to the middle of the ventrals, and a 

 httle beyond the tip of the ventrals; the pectoral spine is about as long as the head 

 less the opercle and provided with about 13 long recurved teeth along the basal 

 three-fifths of the spine. The tip of the dorsal is dark. 



In 6979 the maxillary barbel extends to the end of the base of the anal. In 

 the largest of 6977 it extends just about to the middle of the ventrals; eye 4-4.5; 

 interorbital 4.66-5.
