GILBERT AND STAUKS — FISHES OF PANAMA BAY 



■j:i 



91. Lycengraulis poeyi (Kner it- Steinduchner). 



Seven spocinieii.s were Uvken, tlie largest 198 rara. in total length. 



In some of the specimens the pectorals scarcely reach to the base of the 

 ventrals, while in others they reach a very liltle past this point. Tlie gill-rakers 

 become shorter and somewhat thicker witli age. 



We have compared these specimens with a single sjiecimun of L. grossidcns 

 from Pernambuco, Brazil. The latter specimen seems to differ from L. poeyi in 

 having a slightly longer maxillary, a greater distance separating the lip of snout 

 from lower angle of cheek, and in the slightly larger teeth, which are more nneven 

 and more widely spaced.
