much smaller spike-like teeth. In dentition, Pseiidopcecilia, although 

 having much heavier teeth, more closely resembles Neoheterandria 

 than it does Heterandria. 



The anal of the male is an elongate organ with a decurved tip, 

 equalling in length about two-fifths of the length of the fish. The 

 ventrals are minute and unmodified. The anal in males is inserted at 

 about the second fifth of the entire length. 



Another character, possibly peculiar to this genus, is the series 

 of large pores about the margin of the pre-operculum.

This species may be identical with the preceding, but seems to difi'er 

 in the number of scales. It has scales 3-29 or 30-4 (to ventrals). 

 P. festce is said to have 33-35 scales in a longitudinal series and 12-13 

 in a transverse series.

The anal fins show slight differences which may be specific. Regan's 

 figure of the anal of the male of P. festce shows nine or more hooks 

 on the third prolonged ray. In all of six examples of P. fria examined 

 for this character, the number of these spines is eight.
