GILBERT AND STAKKS — FISHES OF PANAMA BAY 



153 



The groove before eye is very faint, scarcely to be made out in some of our 

 Panama siiecimens. Dorsal very slightly falcate in the type and in larger specimens; 

 in small and half-grown examples only, is it sharply angulated. The anal is rather 

 sharply rounded. In life the sides are marked with many narrow vertioal wavy 

 blue lines. 



The species is easily distinguished from B. poh/kpis by the thicker body, the 

 larger scales, the darker and more variegated coloration, the much reduced preocular 

 groove, and the less falcate fins. In B. iMhjlepis, the upper margin of the dorsal 

 fin is deeply concave for the whole length; in B. naufragium, the greater part 

 of the upper margin is convex, a few only of the anterior rays projecting, making 

 that part of the fin concave. The caudal lobes are also much shorter in this species, 

 while the middle rays are more produced. The plates are much more roughly 

 granular, and are fewer in number. The lips are much thicker and more deeply 

 plicate, the peripheral folds being densely papillose. The ventral stay is more 

 robust, and the circumoral area is devoid of plates.

We describe as new the species that has commonly been referred to B. capis- 

 trntus on the Pacific coast of Central America. B. capidratus was probably based 

 on East Indian material, but we have had for comparison specimens from the
