108 SURGEON F. DAY ON SOME NEW [Jail. 21, 



slightly broader than high, its greatest width being equal to the post- 

 orbital portion of the head, the summit of which is somewhat flat 

 and snake-shaped. No occipital crest, barbels, nor warts on the 

 head. Cleft of the mouth somewhat oblique, the lower jaw slightly 

 the longer ; the posterior extremity of the maxilla extends to beneath 

 the anterior margin of the orbit. Teeth, an enlarged outer row in 

 the lower jaw, the external of which, on either side, is a moderately 

 or small recurved canine. Fins : the distance of the first dorsal from 

 the orbit equals the distance from the snout to the base of the pec- 

 toral fin, its second spine is elongated in some specimens, being 

 nearly as long as the head ; second dorsal and anal of about equal 

 development and highest posteriorly : caudal wedge-shaped ; ventral 

 reaches halfway 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 the anal fin. Colours : 

 olive, a dark green spot above the 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 at 

 the top of the caudal fin, in its last half; anal whitish, its basal half 

 covered with fine black dots. 



Hab. Bombay, where it is not uncommon, attaining 5^ inches in 

 length. 



Gobius brevirostris, Giinther. 



I obtained at Kurrachee three specimens of this fish, up to 3^ 

 inches in length. A few rows of scales exist on the head in the 

 larger, but none on the smaller specimens. 



Gobius planifrons, sp. nov.

Length of head -|, of caudal T 2 T , height of body T 2 T of the total 

 length. Eyes superior ; diameter ^ of length of head, 1 diameter 

 from end of snout, and 1| apart. Head as broad at the opercles 

 as its length excluding the snout ; its height equals half its length ; 

 its upper surface flat. Mouth anterior, cleft horizontal, lower jaw 

 the longer ; width of gape equals half the length of the head ; and the 

 posterior extremity of the maxilla reaches to half a diameter behind 

 the orbit. Fine tentacles near the nostrils, and rows of small warty 

 glands on the scaleless head. Teeth, canines absent. Fins : first 

 dorsal low, being about half as high as the body below it, the second 

 fin higher than the first ; silky pectoral rays ; caudal rounded. 

 Scales finely ctenoid, disposed in very irregular rows, none on the 

 head ; they merely reach on the nape halfway between the base of 

 the first dorsal and the posterior edge of the orbit. Fifteen rows 

 exist between the base of the second dorsal and the anal fin. Colours : 

 dark olive, fins very dark grey ; second dorsal spotted ; a black 

 blotch at the upper part of the base of the pectoral fin. 



Hab. Bombay, where one specimen, 4 inches long, was obtained.
