[Received November 25, 1872.] Amongst the numerous species of fish which I have lately obtained at Bombay, Calcutta, or Kurrachee, the following appear to be undescribed or but little known. GOBIUS MASONI, sp. nov. D. 6 I L P. 19. V. i- A. 10. C. 12. L. 1. 34. L. tr. 11 * 1 11 o Length of head \, of caudal £, height of body ^ of the total length. Eyes, diameter f of the length of head, 1 diameter from the end of snout, and \ a diameter apart. Upper profile of the head rounded, its width equal to its height or to its length without the snout. No crest on the head, glands, or barbels. Cleft of mouth rather oblique, the lower jaw somewhat the longer ; the posterior extremity of the maxilla extends to below the middle of the orbit. Teeth, a large recurved canine on the outer side of an enlarged row in the lower jaw. Fins : dorsal spines filiform, the longest two thirds as high as the body below it; second dorsal fin highest posteriorly, where it equals that of the body ; anal similar to the second dorsal; caudal wedge-shaped ; ventral not extending so far as the vent, its basal membrane well developed; none of the pectoral rays silk-like. Scales anterior to the middle of the first dorsal fin much smaller than those on the remainder of the body, which are ctenoid and in eleven rows between the base of the second dorsal and the anal fin; they are extended over the upper part of the cheeks and opercles. Colours: deep olive, with numerous small blue spots along the side, each in the centre of a single scale; an ill-defined dark band passes from the eye to the tail. First dorsal with its upper two thirds violet, tinged with yellow, its lower third deeply spotted with black; second dorsal with a violet and yellow margin, its lower three fourths spotted with black, most densely superiorly ; anal dark, with a few small round white spots between some of the rays ; caudal darkish with irregular blotches, and having its upper margin stained with yellow; ventrals nearly black, with an orange edging ; pectoral without marks.
