The casabe is a small fish of wide distribution along our east 

 •coast, ranging from Cape Cod to Brazil; it is common in the- 

 Gulf of Mexico, the Caribbean, and in Cuba, but rather rare f rom- 

 Charleston northward. The only authority for its occurrence* 

 in New York waters till recently has been Cuvier and Valen- 

 ciennes, who claimed to have a specimen from New York. De 

 Kay did not regard it as a member of the fish fauna. In 1899,. 

 however, W. I. De Nyse secured several fine examples at Graves- 

 end beach, L. I., and one of these, 8 inches long, is now 

 in the U. S. National Museum, where it is numbered 49219. 



The fish grows to the length of 10 inches. It has no value a& 

 foodj but is a beautiful species. 



Genus trachinotus LacepMe 

 Body compressed, moderately elevated, the general outline- 

 ovate; caudal peduncle short and rather slender; abdomen not 

 trenchant, shorter than the anal fin; head moderately com- 

 pressed, very blunt, the snout abruptly truncate; mouth nearly 

 ^ horizontal the maxillary reaching the middle of the eye; premax- 

 illaries protractile; maxillary without distinct supplemental 

 bone; jaws, vomer and palatines with bands of villiform teeth^ 

 which are deciduous with age; preopercle entire in the adult; gill 

 rakers short; gill membranes considerably united; spinous dorsal 

 represented by six rather low spines, which are connected by 

 membrane in the young but are free in the adult. In old speci- 

 mens the spines appear small on account of encroachments of 

 the flesh, and ultimately often disappear. Second dorsal long,, 

 elevated in front; anal opposite to it and similar in form and 

 size; two stout, nearly free spines in front of anal, and one con- 

 nected with the fin, these often disappearing with age; scales- 

 small, smooth; lateral line unarmed, little arched; no caudal 

 keel.
