where it is interrupted, and then proceeds to the tail, 

 passing a little beneath the anal, as in the preced ins- 

 species. 



The colour is nearly the same as in the preceding, 

 only a little deeper, and the caudal fin bluish. The 

 fins contain the same number of rays. Not having 

 time to open the species, I am unacquainted with 

 its sex. It inhabits the Caribbsean sea, near Gua- 

 daloupe, Martinique, and Domingo, where in com- 

 mon with the other species, it is known by the name 

 of Balao.

Dorsal and anal fin equal in length and height ; 

 upper beak about the length of the diameter of the 

 eye ; pectoral fins half the length of the lower jaw ; 

 a blue and argentine band on each side continued 

 from the pectoral to the caudal fin. 



Observations. Body four times the length of 

 the lower beak from the angle of the mouth to the ex- 

 tremity of the tail. The form of this species differs 

 little from that of the preceding. The dorsal and 

 anal fins, equal in length and height, are perfectly 

 opposite, elevated anteriorly, and at the base poste- 

 teriorly. Pectoral fins pointed ; the ventral small 

 and truncated ,* the caudal forked, the lobes pointed, 

 the inferior lobe longer. The lateral line, more ele- 

 vated, passes above the ventral and anal fins, but is 

 not as in the preceding species interrupted by the 

 ventral fin. The eyes are large, and a little oblonsr,
