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.

Habitat.—Southeastern Brazil. 
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 
little 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.
