Only known from the above-described example taken many years 

 ago in Santo Domingo with specimens of Albula vulpes (Lirmseus), of 

 the same size and sex, differing chiefly as pointed out above. Albula 

 vulpes further differs in having the preopercular membrane extended 

 back nearly to the gill-opening above, besides having the preopercle 

 entirely inclined anteriorly along its hind edge and ridge. Albula 

 also shows other minor differences, such as the aperature of the 

 adipose eyelid, a simple opening and not folded over below, snout 

 much shorter, and the eye more median in the head length. The 

 accompanying figure is shown with the caudal fin restored, the tips 

 of which are now damaged. 



(Nrjfia, thread; xrepov, fin; with reference to the last dorsal and 

 anal rays.)
