extremely fine towards the encl. A large round dark spot on each 

 side, sitúate on the lateral line, a little anterior to the dorsal fin.

Fam. Cyiwinidce. 



Barbus caudimarglnatus, nobis. n. s. One of those Ststomi 

 (for sucli they essentially are) whieh, having four barbules or tenta- 

 cles, are currently assigned to the great and comprehensive genus 

 Barbtts : such are the B. gordoniües and B. chrysopoma figured 

 by Valenciennes, and the B. sarama, (B. H.), Val., which is S. 

 immaculatits as described by McClelland.* In the present species 

 the barbules are well developed, the forra less deep than usual in the 

 particular group, the principal dorsal spine robust and passing into a 

 soft ray for its terminal fourth, being finely peetinated behind, and 

 preceded by three distinct spines, the first very minute. About 32 

 scales ou the lateral line, and ten longitudinal series of scales. 

 JD. 4-8.— A. 7 (the last divided). 



Colour silvery, above darker and greenish ; wifch an irregular ver- 

 tical black mark behind the gills, and broad black upper and lovver 

 margins to the caudal fin ; the rest of the caudal, vvith the ventrals 

 and anal, bright crimson (which soon disappears in spirit). Length 

 4 in., by 1^- in. from dorsal to ventrals. Vertical diameter of the 

 eye fully half that of the head. Irides palé golden. Tenasserim 

 provinces.f 



Capoeta macrolepidota (?), K. et v. H. Specimen 2 in. long. 

 No serrature discernióle on the dorsal spine, and I distinguish seven 

 anal rays. The late Dr. Cantor gives tliis species as inhabiting the 

 Tenasserim provinces ; and it and Leuciscüs basbora are the only 



* His figure (As. Res. XIX, II, Pl. XL, f. 5), I take, from the colouring, to 

 represent a common species oí' Systomüs with one pair of vevy minute tentacula, 

 otherwise resembling S. sopuore except in the absence of markings. For this 

 the ñame immactjlatüs might be retained. It grovvs to about double the size 

 of S. sopuoee. 



t ' Black and red-tailed Sjstomua' of the Rev. F. Mason's ' Natural Produc- 

 tions of Bunna.' Several species are indicated in this work, as Rohita vülga* 

 bis, R. calbasu, and R. nandina ; also a large Barbel affined to B. tob, (13. H.), 

 which he terms B. Mortoniüs ; and a mountaiu Barbel with minute scales, 

 of the Okeinüs group, which requires examination.
