Fishes of the Western North Atlantic 133 



chiostegals (13 or 14). From members of the Clupeidae they differ in having a well- 

 developed lateral line and undeveloped gill rakers. 



Range. Only two living genera, Albula and Dixonina., are recognized." The former 

 has a world-wide distribution in warmer seas, and the latter is known from both coasts 

 of tropical America. 



Key to Western Atlantic Genera 



I a. Last ray of dorsal and anal not prolonged; snout only moderately conical, pro- 

 jecting only about a third of its length beyond mandible; maxillary not reaching 

 eye. Albula Scopoli 1777, below. 



lb. Last ray of dorsal and anal much prolonged; snout sharply conical, projecting 

 more than a third of its length beyond mandible; maxillary reaching nearly 

 to middle of eye. Dixonina Fowler 191 1, p. 143.

Characters. Dorsal and Anal fins with the last ray not produced. Maxillary 

 falling short of vertical from front border of eye. Snout projecting about a third of its 



14. Dr. Hildebrand evidently excluded from the Albulidae the deep-water genus Pterothrissus, which is known from 

 the coasts of Japan and West Africa and which may eventually be found in the western North Atlantic. Pterothrissus 

 differs widely from Albula and Dixonina in the very long, many-rayed dorsal fin. — G. S. Myers.
