A COLLECTION OF FISHES FROM SUMATRA. 529 



orbital area above. Four series of scales on cheek. Basal portions of vertical tins 

 all with reduced and crowded scales, on caudal they become minute and extend 

 well over lobes. Bases of pectoral and ventral more or less with minute scales. 

 Lateral line a little convex, somewhat concurrent with dorsal profile, approaching 

 it more closely posteriorly, running a little high on side of caudal peduncle and well 

 out on base of caudal. A long pointed scaly flap at base of ventral. 



Origin of spinous dorsal behind that of pectoral, spines slender, first shortest, 

 five or six immediately following highest, and others graduated to last, which 

 is shorter than any excepting first. Margin of fin hardly notched. Origin of 

 soft dorsal over tip of pectoral, anterior rays longest, and margin of fin a little 

 convex behind. Anal inserted a little behind origin of soft dorsal, spines slender, 

 first very short, and second and third about equal. Soft anal graduated from first 

 rays, which are longest, and margin of fin nearly straight. Caudal deeply forked, 

 lobes slender, pointed, and upper longer. Pectoral long and a number of upper 

 rays long. Ventral inserted behind origin of pectoral, pointed, and spine about 

 two-thirds length of fin. Anus nearer tip of ventral than origin of anal. 



Color in arrack rich olivaceous-brown above, more or less washed with aolden- 

 green, middle rays of each caudal lobe yellowish-green. Lower surface of body, 

 together with lower side of trunk, head and caudal peduncle, deep rosy. Edges of 

 caudal lobes, and several of middle rays, paler rosy. Dorsal fin olivaceous-brown, 

 margin or border broadly blackish. Ventral and anal orange, former inclining to 

 deep red. Pectoral deep orange, with axil and a distinct blotch at base of upper 

 rays jet-black. Peritoneum silvery. 



Length 5|^ inches. 



Type No. 27,621, A.. N. S. P. Padang. 



Nineteen examples. Closely related to Ccssio lunaris Ehrenberg as identified 

 by Bleeker's East Indian examples. It agrees with it more or less in the large 

 scales, fin radii, and deep body. C. lunaris has fewer scales in a vertical series 

 above the lateral line, and a differently colored caudal, the tip of each lobe black.
