158 Beport on some Fishes received from tlie Sitang JRiver. [No. 2, 



Cj/prinidce vvhicli are included in his Catalogue of Malayan fishes. 

 Tenasserim. 



Genus Osteobrama, Heckel. Comprising certain Bream-shaped 

 Carps with minute scales, as exemplified by the (Rohtee) Vigousii 

 and (B.) Ogilbii of Sykes, and the (Leuciscus) alfredianus of 

 Valencidiines.* Dr. Bleeker includes them in Systomus. 



O. MiCEOLEPrs ; Systomus microlepis, nobis, J. A. S. XXVJI, 289. 

 (' Tenasserim Bream' of Masón.) A specimen obtained by Mr. Atkin- 

 son at Maulmein ; and I arn now certain that the example formerly 

 described is also from Maulmein, having been sent many years ago by 

 the Rev. F. Masón. Colour silvery-ash above the lateral line, whité 

 belovv it, and a semi-obsolete large blackish spot near base of tail : 

 fins white, a little tinged with yellow ; and the irides apparently palé 

 golden. From analogy with kindred species, it is probable that this 

 fish attains a weight of 3 or 4 íbs. 



O. cotis ; Cyprinus cotis, B. H. ; Abramis cotis apud McClelland ; 

 Leuciscus alfiedianus (?), Val. A Tenasserim specimen 3 in. long 

 accords with the description, excepting in having but 32 instead of 

 35 rays to the anal fin'.f The second dorsal ray is spinous, but very 

 slender, and is conspicuously serrated on the hind-edge. In lieu of 

 the row of four dots cióse under the lateral line and immediately 

 behind the gill-cover, figured by Buehanan Hamilton, are four scales 

 of the lateral line having remarkably large tubes ; and most of the 

 soft rays of the dorsal are marked anteriorly with black, and the 

 rays of the anal are spotted with the same anteriorly, as seen with 

 the help of a magnifier. The merest trace of a slight dark spot in 

 front of the dorsal fin. 



* Figured in the Histoire des Poissons by this ñame ; but described as L. 

 Duvaucelii (by which appellation a species of Systomus is also described and 

 figured),— having "le premier rayón de la dorsale forte et un peu déntele." From 

 Díipal. It appears that three divisions of these spined Bream-carps are recog- 

 nised by Heckel, bearing the ñames Acantrobrama, Osteobrama, and G-los- 

 SODon. I am unacquainted with the distinctions ; but find that Eohter 

 Ogilbii, Sykes, is assigned to Osteobrama, as is likewise the (Cyprinus) 

 cotis, B. H. Vide Hugel's Fauna von Kasc7imir, p. 392. 



t McClelland also counts 32 rays. (As. Ees. XIX, II, 588). But Valenci- 

 ennes counts 36 in his alfredianus.
