D. 21, P. 17, V. 8, A. 42, C. 27, L. 1. 70. 



Height of body nearly 4 in the total length. Suborbital and opercle striated. TeetJi — very distinct in 

 premaxillaries and mandibles. Fvns — pectoral large and rounded towards its extremity, and extending beyond 

 the insertion of the ventrals which last are small, and arise about 8 or 9 rows of scales anterior to the origin of 

 the dorsal. Anal elongated. Golows — silvery. 



Habitat. — A single dried example (20 inches long) was brought from Pondicherry. 



Genus, 7 — Opisthoptieus, Gill, 



Pristigaster, sp. Cuv. 



Branchiostegals six. Bo3y oblong, compressed. The lower jaw projecting ; the maxilla elongated posteriorly. 

 Small sharp teeth wi the jaws, palatines, pterygoids and tongue : none on the vomer. Dorsal fin situated behind the 

 commencement of the anal, which has many rays : ventrals absent. Scales of moderate or small size, very deciduous: 

 serrature along the abdominal profile well developed. 



This genus is closely allied to the last, the chief difference being absence of ventral fins. Amongst 

 examples of Pellona occasional ones are seen in which this fin is deficient.

 . Length of head 54 to 5|,"of caudal 6, height of body 3f to 4 in the total length. Eyes — diameter 2| to 3 

 in length of head, 2/3 of a diameter from end of snout, 1/3 of a diameter apart. The maxilla reaches to below 

 the anterior third or middle of the orbit, its length nearly half of that of the head : lower jaw very prominent : 

 opercle 1/3 t9 3/4 higher than wide. Teeth — on jaws, tongue, palatine, and pterygoid bones. Fvrts — origin of 

 dorsal rather nearer base of caudal than to the axilla : the pectoral, somewhat longer than the head, reaches to 

 over the first anal ray, and that fin commences midway between the end of the snout and the posterior 

 extremity of its own base : caudal forked. Scales — very deciduous : 28 to 32 spines along the lower profile* 

 Gill-rakers about 28, and nearly as long as the eye. Pseudobranchise 'well developed. Golows — silvery. 



Dr. Bleeker questions whether the Malay Archipelago species is identical with the Malabar one, as ia the 

 latter the pectorals are longer than the head, reaching to the commencement of anal fin, the body is higher, and 

 the caudal shorter. 



Habitat. — From Gwadur in Beloochistan and Sind, through the seas of India to the Malay Archipelago. 

 It attains at least 9 inches in length. 



Genus, 8 — Raconda, Gray. 



Apterygia, Gray. 



Branchiostegals six. Body oblong, compressed. The lower jaw projecting : the maxilla may he elongated 

 posteriorly or truncated. Small teeth on the jaws, palatines, pterygoids, and tongue : none on the vomer. Dorsal 

 and ventral fms absent : anal elongated. Scales rather small and deciduous. Serratu/re along the abominal profile 

 developed but weak. 



This genus differs from_ the last in having no dorsal fin. It appears that the species is more abundant 

 along the coast of India than in the Malay Archipelago.
