long, beginning behind front of anal, its last rays much elevated in the 

 young, becoming low in the adult ; caudal deeply and unequally emar- 

 ginate; ventrals inserted midway between middle of eye and base of cau- 

 dal. Green above; no lateral band. Length 3 to 4 feet. West Indies, 

 occasionally straying northward (Buzzard's Bay, Goode; Beaufort, N. C.,

 same species, as appears to be the case. (Acus, the needlefish, from acus, 

 needle.) (En.)

325. ATHLENNES,* Jordan & Fordice. 



Athlennes, JORDAN & FORDICE, Proc. U. S. Nat. Mus., 1886, 342, (hians). 



This genus is close to Tylosurus, differing chiefly in the greatly com- 

 pressed, almost ribbon-shaped body. The single species is American. 

 (afi'Aevvfa, without mucosity, a name applied by some medieval authors 

 to the fish called by them QeMvij or Acus, Esox Mone, L.) 



* This name was inadvertently written "Athlennes" by its authors, and as this form has now 

 been several timed used it may remain so. Ablennes was intended, as the etymology shows ; 

 Athlennes is meaningless, but euphonious.
