158 Report on some Fishes received from, the Sitang River. [No. 2, 



Cyprinidce winch are included in his Catalogue of Malayan fishes. 

 Tenasserim. 



Genus Osteoerama, Heckel. Comprising certain Bream-shaped 

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

 and (R.) Ogilbii of Sykes, and the (Leuciscus) aefbediastijs of 

 Valenciennes.* Dr. Bleeker includes them in SYSTOiius. 



O. miceolbpis; Systomus microlepis, nobis, J. A. S. XXYII, 289. 

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

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

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

 the Rev. F. Mason. Colour silvery-ash above the lateral line, white 

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

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

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

 fish attains a weight of 3 or 4 lbs. 



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

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

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

 38 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 close under the lateral line and immediately 

 behind the gill-cover, figured by Buchanan 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 name ; but described as L. 

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

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

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

 nised by Heckel, bearing the names Acanteobraha, Osteobrama, and G-los- 

 sodon. I am unacquainted with the distinctions ; but find that Eohteb 

 Ogilbii, Sykes, is assigned to Osteobeama, as is likewise the (CyprinusJ 

 coxis, B. H. Vide Hugel's Fauna von Kaschmir, p. 392. 



t McClelland also counts 32 rays. (As. Ees. XIX, II, 5SS). But Valenci- 

 ennes counts 36 in his alfkediakus.
