rather large conical teeth ; a triangular patch of vomerine teeth and 

 a moderately broad band of palatine teeth ; praeopercular border 

 rounded, feebly serrated ; two small, indistinct opercular spines ; 

 head densely scaled, with the exception of the end of the snout, the 

 lips, and the lower jaw. Gill-rakers about as long as the gill-fringes, 

 27 or 28 on lower part of anterior arch ; pseudobranchiae very large. 

 Dorsal XI 18, originating above axilla ; spines weak, fourth and fifth 

 and eleventh longest, or -f- the length of the head, | the length of the 

 longest soft rays ; the soft dorsal densely scaled, high and pointed in 

 front, with slightly concave border. Anal III 13, opposed to soft 

 dorsal and similar in shape ; spines rather feeble, graduated, first 

 very short, third twice as long as second and as long as longest 

 dorsal. Pectoral very asymmetrical, obtusely pointed, f length of 

 head; ventral quite as long, reaching vent. Caudal slightly 

 emarginate. Caudal peduncle 1% as long as deep. Scales 85^-f, 

 strongly ctenoid, with smaller ones between them ; lateral line very 

 indistinct, on about 55 scales. Blackish-brown ; maxillary and 

 cheek lighter, greyish-brown, with a blackish oblique streak from 

 the prseorbital to the angle of the prseopercle. 



This species is described from two specimens. The larger 

 measures 410 mm., the smaller 250. 



It is evidently closely related to the fish from the Mekran Coast 

 and Sind, described by Day as Hapalogenys peter si, and for which I 

 have proposed the genus Dinoperca. It differs in the absence of the 

 barbel-like papillae about the lips which caused the Indian species to 

 be referred to Hapalogenys ; also in the higher dorsal and anal fins, 

 the shape of the body and fins, and, apparently, in the larger scales 

 above the lateral line, Day having given the number as about 100. 



EPINEPHELUS GBAMMATOPHOBUS. (Plate III.) 



Teeth in narrow bands, in two series on the sides of the mandible ; 

 canines strong. Depth of body 3 to 3r times in total length, length 

 of head 2f to 2f times. Snout as long as diameter of eye, which is 

 4 to 4^- times in length of head ; interorbital width 5^- to 6 times in 

 length of head ; lower jaw projecting ; maxillary extending to below 

 posterior border of eye, the width of its distal extremity to f 

 diameter of eye ; serrse at angle of prteopercle slightly enlarged ; 

 opercular spines equidistant, lower much further back than upper ; 

 opercular flap pointed ; head nearly entirely covered with cycloid 

 scales ; maxillary naked. Gill-rakers nearly as long as gill-fringes, 

 15 on lower part of anterior arch. Dorsal XI 17, originating above
