GILBEKT AND STAKES — FISHES OF PANAMA BAY 



49 



91. Lycengraulis poeyi {Kner £ Sieindacliner). 



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



In some of the specimens the j^ectorals scarcely reach to the base of the 

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

 become shorter and somewhat thicker with age. 



We have corajiared these specimens with a single specimen of L. grossidens 

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