Height of body i of the total length. Eyes with broad adipose margins. Diameter | of length of head, f of a diameter from end of snout, above 1 diameter apart. Abdominal profile more convex than the dorsal. Jaws of about equal length ; the posterior extremity of the maxilla extends to beneath the centre of the orbit. Opercles smooth. Teeth on tongue; none on jaws, vomer, or palatines. Fins. Dorsal commences rather nearer to the snout than to the base of the caudal. Ventrals situated opposite the commencement of the dorsal fin. Anal in the posterior third of the distance between the posterior margin of the orbit and the base of the caudal fin. Scales regularly arranged behind a line from the opercles to the base of the anal fin, anterior to which they are very irregular. Along the back to the base of the dorsal fin the scales of the two sides meet, so as to form a sort of line somewhat resembling a lateral line in appearance. Serrated scales commence under the middle of the pectoral; ten are posterior to the ventral fin, and ten anterior to it. Colours. Silvery glossed with gold. A dark humeral spot. A row of about eighteen bars passes across the back and descends a short way over the sides. Dorsal fin with a black band in the lower portion of its posterior half. End of tail tipped with black. Hab. Irrawaddi and its branches. Many specimens procured, up to 7 inches in length. PELLONA SLADENI, sp. nov. D. i. P. 11. V. 7. A.J. C. 21. L.l. 48. L. tr. 10. Length of head ^ of length of body, and equal to its height. Eyes with wide adipose lids. Diameter \ of length of head, 1 diameter from end of snout. Ridges on the head slightly diverge posteriorly. Lower jaw very prominent. Fins. First two dorsal rays in advance of anal, the remainder of the fin over it; it arises midway between the base of the caudal and the posterior extremity of the opercle. Pectoral reaches to nearly the end of the ventral, which is small. Caudal forked. Twenty spinate scales exist on the abdominal profile anterior to the ventral fins, and eleven posterior to them. Colours. Silvery ; opercles golden. Caudal edged with black. Specimens up to 7 inches from the Irrawaddi, at Mandalay. I have named the species after Major Sladen, Political Resident at the court of the King of Burma, who greatly assisted m e in collecting specimens, as well as in acquiring information on the fishes of that mismanaged but magnificent country. |
