Cauca !. 
The specimens from Costa Rica referred to P. sphenops, one of which is figured 
(Tab. XIII. fig. 2), appear to differ from P. sphenops in the greater length of the 
anterior dorsal rays and in the presence of a dark spot at the base of the dorsal fin. 
This species seems to be the one described by Steindachner as Girardinus cawcanus.
