Type. Imperfect fish ; Boyal Lokemian Mus^m, Prague. 
A comparatively robust small species, attaining a length of about 
0*15. Length of head with opercular apparatus slightly less than 
maximum depth of trunk, which considerably exceeds one third the 
length of fish to base of caudal fin. Fourth dorsal fin-spine longest, 
the third twice as long as the first. 
The two dorsal fins are not so clearly separated in this species as 
in the typical P. angusta, and the tenth or hindermost spine has not 
been observed.
