Heio-ht of body nearly 4 in tlie total length. Suborbital and opercle striated. Teeth—Yery distinct in 

 premaxillaries and mandibles. F/h.s— pectoral large and roiinded towards its extremity, and extending beyond 

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

 the dorsal. Anal elongated. Colours— silvery. t, j- i, 



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



Genus, 7 — Opisthopterus, Gill. 



Pristigaster, sp. Cav. 



Branchw.^te(jals six. Body ohlonrj, compressed. The lower jaw p-rojectiiuj ; the maxilla elongated posteriorly. 

 Small sharp teeth in the jaws, palatines, ptenjgoids and tongue : none on the vomer. Dorsal fin situated lehmd the 

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

 serrature alonn the ahdominal profile well developed. , . , ^ , , n * i. 



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

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

Length of head 5* to 5|, of caudal 6, height of body 3-| to 4 in the total length. %ft5-diameter 2f to 3 

 in len.'th 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 to 3/4 higher than wide. Teeth— on jaws, tongue, palatine, and pterygoid bones. Fins— ovigm ot 

 dor.sal rather nearer base of caudal than to the axilla : the pectoral, somewhat longer than the head, reachesto 

 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— vevj deciduous : 28 to 32 spines along the lower profile. 

 Gill-rakers about 28, and nearly as long as the eye. Pseudobranchiffi well developed. Co?oi(W— silvery. 



Dr Bleekerquestions whether the l>Ialay Archipelago species is identical with the Malabar one, as in the 

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



^ ^'^\ahitat.— From Gwadur in Beloochistan and Smd, through the seas of India to the Malay Archipelago. 

 It attains at least 9 inches in length. 



Genus, 8— Racosd.4, Ch-ay. 



Apten/qia, Gray. . . , • , , -,7 77^7 



BrancMostegals six. Body ollong, compressed. The lower jaw projecting : the maxilla may be elongated 



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



and ventral fins absent : anal elongated. Scales rather small and deciduous. Sei-rature along the alominal projile 



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.
