Plate Gl, fig. 4 (life-size from Bombay) is 0. v&nenatus, Cuv. and Val. : plate 59, f. 5, is G. viridi- 

 punctahis, C. "V. from Madras : plate 63, fig. 4, is a cui-ious abnormal fonn showing a deficiency of 

 two anal rays. 



Habitat. — Sind, ttrougli tlie seas of India, it is most common at Bombay and Madras, up to at least 

 5 inches in length.

Length of head 4i to 4J, of caudal 5 to 6, height of body 6 to 7 in the total length. Ei/es — somewhat 

 superior, diameter 5 to 6 in the length of head, 1^ diameters from end of snout, and 1 apart. Head slightly 

 broader than high, its greatest wdth being equal to the length of its postorbital portion, the summit 

 of which is somewhat flat and snake-shaped. No occipital crest, nor warts on the head : a pair of short barbels 

 mider the symphysis of the lower jaw. Cleft of mouth somewhat oblique, commencing opposite the middle of the 

 eye : the lower jaw a little the longer : the posterior extremity of the maxilla extends to beneath the anterior 

 margin of the orbit. Teeth — several rows in both jaws, an enlarged outer one in the mandibles, the external of 

 which on either side is a moderately or small recurved canine : outer row in premaxUlaries likewise enlarged, and 

 a lateral canine in large specimens. Fins — the two dorsals not widely separated, the distance of the first dorsal 

 from the orbit equals the distance from the snout to the base of the pectoral fin, its second spine is elongated in 

 some specimens, being nearly as long as the head, last dorsal ray divided to its base. Pectoral rays silk-like, second 

 dorsal and anal of about equal development and highest posteriorly : caudal wedge-shaped : ventral reaches half 

 way to the vent. Scales— ctenoid on the body, cycloid on the head, they are much smaller anterior to the dorsal 

 fin than posterior to it : they cover the cheeks and opercles, and on the top of the head as far as the snout : are 

 in rather irregular rows, eight being between the origin of the second dorsal and anal fins, where they are 

 angular : about 28 rows before the dorsal fin. Colours — olive, a dark green spot above the upper margin of the 

 opercle, about six indistinct blotches along the sides : dorsal and caudal fins stained with dark, and having some 

 indistinct spots or bars :* a yellow ocellus, with a black centre, at the top of the caudal fin in its last half : anal 

 whitish, basal half covered with fine black dots : ventrals yellow. 



Habitat. — Bombay and Sind, to 6 inches in length. The specimen figured (life-size) is from Bombay.

Length of head 4^, of caudal 5 to h\, height of body 5 in the total length. iJi/e.?— somewhat superior, 

 diameter 5i to 6 in the length of head, 1^ diameters from end of snout, and 1 to 1:^ apart. Profile of head bluntly 

 rounded, its greatest width equalling its length excluding the snout, its height a little more : cleft of mouth 

 oljlique, commencing opposite lower edge of eye : lower jaw anterior, the posterior extremity of the maxilla 

 extends to below the middle of the orbit. Numerous rows of fine wart-Hke glands along the opercles, nape, and 

 mandibles. Teeth — in viliiform rows in both jaws, there is an external enlarged row in the upper jaw, with two 

 large canines : from 12 to 15 also enlarged in front of the lower jaw, on either side of the outer row is a very 

 large recurved canine. Fins — first dorsal low, its spines filiform, and the longest about half the height of the 

 body below it : the second dorsal rays increase in length posteriorly : pectoral destitute of silk-like rays : caudal 

 wedge-shaped. S^caZes— ctenoid, before the first dorsal fin there are 25 rows, anterior to which they are rounded 

 and smaller than those in the remainder of the body, where they are angular : none on the cheeks, a few along 

 the upper margin of the opercles, superiorly they do not extend so far forwards as to above the posterior margin 

 of the orbit : 10 rows between the origin of the second dorsal and anal fins. Air-vessel — large. Colours — olive, 

 with numerous brilliant blue spots on the nape and behind the pectoral fin : some blackish ones along the sides. 

 Dorsal, anal, ventral, and caudal black : pectoral yellow, margined with black. 



Habitat. — Bombay, to 4 inches in length.

Length of head 4i, of caudal 5|, height of body 6|- in the total length. Eyes— somewhat superior, 

 diameter 1/5 to 1/6 of length of head, IJ diameters from end of snout, and 1/2 a diameter apart. Greatest 

 width of head 2/3 of length, height equals its length without the snout. Cheeks swollen. No warts on cheeks, 

 no crest on nape, nor tentacles above the orbit. The orifice of a canal behind posterior-inferior angle of eye. 

 Mouth anterior, oblique, commencing opposite the lower edge of the eye, jaws of equal length, the maxilla 



• Specimens from Sind are more ban-eel than are those from Bombay.
