Length of head 4 to 4-1-, of caudal 5, height of body 6 to 7 in the total length. Eyes — diameter 1/3 to 

 2/7 of length of head, 1 diameter from end of snout, 1/4 of a diameter apart. Snout obtuse, convex. 

 Head as broad as high, and equalling two-thirds of its length. Jaws of about equal length. Cleft of mouth 

 very slightly oblique, the maxilla reaching to below first third of orbit. Teeth — in villiform rows, no canines. 

 Fins — first dorsal somewhat lower than the second or than the body. Pectoral as long as the head : caudal 

 rounded. Scales — ctenoid, they extend on to the crown of the head, 13 rows before the base of the 

 dorsal fin : seven rows between the bases of the second dorsal and anal fins. Colours — green, with numerous 

 oblong brown spots, generally in three or four rows, also yellow dots in the centre of some of the scales : all the 

 fins, except the ventral, dotted with black. 



Some specimens in the Calcutta Museum were marked Gobius maculatus, Blyth, but I have been unable 

 to ascertain if such a name was ever published. Genus Acentrogobms, Bleeker MSS. 



Habitat. — Red Sea to the Malay Archipelago, the specimen figured is from the Andamans.

Head small, narrower than the body. Eyes — small. Mouth large, the upper jaw the longer. Teeth — 

 sharp. Fins — pectoral and caudal rounded. Scales — ctenoid. Colours — greenish, with many black dots 

 clustered into irregular spots resembling clouds in form : dorsal and caudal fins spotted. A figure of this 

 species 2-^ inches in length exists amongst Hamilton Buchanan's MSS. drawings at Calcutta. 



Habitat. — Lower portion of the Hooghly, to three or four inches in length.

Length of head 4j to 4|, of caudal 4|, height of body 5j in the total length. Eyes — diameter 2/9 to 

 1/5 of length of head, 1a diameters from end of snout, and 3/4 of a diameter apart. Greatest width 

 of head equals its length excluding the snout, whilst its height equals its length behind the eye. Cleft of mouth 

 slightly oblique, the maxilla reaching to below the first third of the eye. Teeth — in villiform rows in both jaws, 

 the outer row of which is slightly enlarged. No canines. No glands, warts, or barbels on the head. Fins — 

 first dorsal lower than, or of equal height to, the second, the anterior rays of which equal the height 

 of the body. Pectoral as long as the head excluding the snout. Ventral does not quite reach the anus. 

 Caudal rounded. Scales — those on the nape rounded, cycloid, and in about 20 rows anterior to the dorsal fin, 

 those on the rest of the body feebly ctenoid, and in 11 or 12 rows between the bases of the second 

 dorsal and anal fins. An anal papilla. Colours — brownish, irregularly marbled : sides of head and body 

 studded with white spots : dorsal and caudal grayish, dotted with black, forming three rows on the first and 

 second dorsal fins : the other fins unspotted. In some instances the dorsal, caudal, and pectoral are blackish, 

 with a row of white dots.
