A COLLECTION OF FLSHES FROM SUMATRA. 539 



line, then extending along upper edge of caudal peduncle and out on uppermost 

 caudal rays, where it becomes reddish. From lower portion of third transverse 

 black blotch, a broad salmon-red horizontal band longitudinally and medianly to 

 base of caudal. A similar streak of pinkish hue along lower edge of caudal pedun- 

 cle forward. Dorsal pale yellow, with a median longitudinal band of dusky, broad 

 at first, and narrowing down and fading out on last dorsal rays. Anal whitish, 

 with a dusk}' blotch on first three rays. Caudal with its posterior portion broadly 

 dusky-gray. Pectoral pale, creamy at base, with a black axillary spot at its base 

 above, and terminal portion broadly black. Ventral dilute yellowish. 



Length 6f inches. 



Type No. 27,724, A. N. S. P. Padang. 



One example. Closely related to Thalassoma hardwicke (Bennett).^ It differs 

 in blackish-tipped pectoral and presence of an oblique black band before base of 

 pectoral. Bleeker's figure agrees with melanochir, except that he does not show the 

 pectoral with a blackish extremity. Thalassoma dorsals (Quoy and Gaimard) has 

 been identified witli hardwicke. though it does not appear to have a broad rosy 

 lateral band extending along side of trunk to caudal peduncle. Julis semifasciatus 

 Valenciennes may also be allied or identical with dorsale. and the same may be 

 said oi Julis [Julis] urostigma Bleeker.

Body oblong-elongate, greatly compressed, slightly trenchant, and profiles of 

 trunk more or less similar. Greatest depth at base of ventral, and from that point 

 posteriorly body becoming graduallj' less in depth to caudal peduncle. Caudal 

 peduncle deep, compressed, and its length a little less than its depth. 



Head deep, greatly compressed, large, parabolic, upper profile steep, convex 

 from level with eye to origin of dorsal, and somewhat trenchant. Snout long, com-

' This name apparently has priority over dorsale of Quoy and Gaimard, though I have not been 

 able to consult the original edition of the work as it is not contained in the Academy's library at present. 

 It was published in London by Longman & Co., 1828 to 1839. The copy of the second edition now 

 before me is by Edward Bull, Holies Street, Cavendish Square. It has a prefatory account which is 

 dated " Londo"n, March 1, 1830."
