GILBERT AND STAKES — FISHES OF PANAMA BAY 



49 



91. Lycengraulis poeyi {Kner (t Sleindachner). 



Seven specimens were taken, the largest 198 mm. in total length. 



In some of the specimens the pectorals scai'ccly reach to the base of the 

 ventrals, while in others they reach a very little jiast this point. The gill-rakers 

 become shorter and somewhat thicker with age. 



We have compared these specimens with a single specimen of L. gr-ossidens 

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

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

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

 and more widely spaced.
