ridge along the posterior and superior edges of the orbit, from 

 which the ridge is divided by two rows of fine scales ; serrated 

 ridges also exist on either side of the snout, but all these serrations 

 appear liable to variation, being usually most distinct in the young. 

 Fins first dorsal f height of body, not so high as second, the pos- 

 terior rays of which are f height of body. Caudal cut rather square. 

 Scales ctenoid on the body, in large specimens there are generally 

 about five or even more rudimentary ones at the base of each large 

 one ; they cover the head except the front of the snout 'and its 

 under surface. Interorbital space nearly flat and covered with 

 small scales. Colour depends very much on locality, generally 

 leaden or brownish, sometimes blotched with darker. A scarlet 

 spot at base of pectoral fin, divided in centre by a round black 

 mark. First dorsal nearly black; the second, the anal, and the 

 caudal yellowish with bands of spots, upper edge of caudal some- 

 times reddish. 



Hab. Seas and estuaries of India to the Malay Archipelago ; 

 attaining about 4 inches in length.

Length of head 3|, of caudal fin 5 to 5|, height of body 7 in the 

 total length. Eyes diameter 5 in length of head, If diam. from 

 end of snout, and 1^ apart. Dorsal profile nearly horizontal, snout 

 depressed. Greatest width of head equals length without snout, 

 height equals nearly half its length. Lower jaw somewhat the 

 longer ; the maxilla reaches to nearly below the front edge of the 

 eye. Upper and hind edge of orbit minutely serrated, also two 

 serrated ridges along either side of the snout. Teetfi in numerous 

 villiform rows in both jaws, the outer row in the premaxillaries 

 larger, widely separated, and pointed, the inner row is rather hori- 

 zontal ; outer row in lower jaw anteriorly similar to that in the 

 premaxillaries ; the inner row laterally is enlarged. Fins dorsal 

 spines weak, about half the height of the body ; anterior rays of 

 second dorsal as high as the body and higher than the posterior 

 ones. Caudal rounded. Scales anteriorly extend forwards to 

 snout, those in the interorbital space not being very small. A few 

 scales on the body have each a rudimentary one at its base. Colour 

 brownish, sometimes vertically banded ; first dorsal dark, second 

 yellowish, with rows of brown spots on the rays ; a large black 

 spot surrounded by yellow at base of pectoral fin ; anal and caudal 

 brown-dotted, and having reddish margins. 



Hab. Seas and estuaries of India to the Malay Archipelago.
