equilateral triangle, each side of which is § of the horizontal diameter 

 of the eye ; the band of teeth of the lower jaw is longer, arched or 

 like a horse-shoe. The length of the pointed pectorals is f of that of the 

 head ; the ventrals, slightly exceeding \ of the pectorals, are placed 

 far forward : they commence in the middle of the distance between 

 the anterior margin of the orbit and the root of the caudal. The 

 vertical diameter in front of the ventrals is 6f in the distance between 

 the gill-opening and the root of the caudal. The dorsal commences a 

 little behind the posterior third of the distance between the occiput 

 and the root of the caudal ; the extent of the base is f of the length 

 of the head ; the first and second ray undivided ; the latter and the 

 third are the longest, § of the extent of the base. The last ray is a 

 little elongated. The anal is placed opposite the dorsal, which it 

 resembles in shape and extent. The caudal is but slightly cleft ; the 

 lower lobe equals the length of the head ; the upper one about \ less. 

 The scales are large, rounded ; the vertical diameter of the part 

 exposed is about the double of the horizontal. The abdominal crest 

 is distinct. Tbis species has several characters in common with H. 

 gernaertiy Cuv. and Val., but it differs from that and from all the other 

 species by its peculiar dentition. In Exocoetus volitans, Linne, the 

 pharyngeal teeth before they become worn, are flattened and tricus- 

 pidate. Perhaps it may be inferred that the individuals of the present 

 species are young, although the young of the preceding species have 

 simple pointed teeth. They are numerous at all seasons at Pinang, 

 and are eaten by the natives.

Pectorals excessively large ; head and body scaly with a salient line 

 on each side of the abdomen ; head depressed ; cheeks compressed ; 

 eyes large ; intermaxillaries without pedicles, forming the edge of the 

 upper jaw ; dorsal placed opposite the anal ; intermaxillaries with 

 minute pointed teeth ; pharyngeals with teeth as if paved.
