325. ATHLENNES,* Jordan & Fordice. 



Athlennes, Jordan & Fordice, Proc. U. S. Nat. Mus., 1886, 342, (hiani:). 



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

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

 ((i/j/fi'i'f/f, without mucosity, a name applied by some media-val authors 

 to the fish called by them fSeAoi'i/ or Acus, Exox hclone, L.) 



* This name was inadverteutlj' written " Afhlenncs" by its authors, and as this form has now 

 been several timed UBed it may remain so. Ahlennes was intended, as tlie etymology shows; 

 Athlennes is iueuuiugics«, but euphonious.
