 R. No 3, with a note, by Peron, under the above 

 name, and No. S568 of his Journal, he afterwards 

 considered it as a new genus, which has now been 

 established by Monsieur Cuvierin his Regne Animal. 



b A variety of H. erythrorinchus. 



iNearto Timor and the Isle of France, we met 

 with a species which differs a little from the prece- 

 ding in the form of its body, its color, and the argen- 

 tine band on the side, hut the form of whose dorsal 

 and anal fins were, excepting some difference in the 

 number of the rays, the only distinctive characters 

 which could be remarked. The length of the body, 

 moreover, was in this only three times that of the 

 lower jaw. The dorsal fin is falciform, high, point- 

 ed anteriorly, and very low and straight posteriorly. 

 The anal is as long as the dorsal fin, perfectly oppo- 

 site to it, and almost straight, being only a little ele, 

 vated anteriorly. The pectoral fins are shorter than 

 the half of the lower jaw. The ventrals small and 

 truncated. Caudal fin deeply forked, the lobes une- 

 qual, with the inferior longer.
