On the Fresh Water 



[No. 35, 



toothed ; pectoral spine with 7 or 8 strongish teeth on its terminal half ; 

 occipital spine very short, almost linear. Colour greenish above and 

 on the fins ; yellow on the cheeks and beneath ; length about 6 inches. 

 I have only found it in the river at Manantoddy in Wynaad. 



Bagrus MaJaharicus. New Species. 

 Very closely allied to the last ; differs in its head being slightly 

 shorter, being nearly 4i times in the length of body, height much 

 the same ; pectoral spine with 15 teeth, maxillary cirri reach beyond 

 the ventrals only — D. 1-7, A. 11 — colours blueish leaden above, sil- 

 very beneath; fins yellowish. Habitat. Mountain streams in Malabar. 



Bagrus vittatus. (Bloch.) C. V. 



Head about 4 times in the length of body ; height not quite so 

 much ; eye 4^ times in the head, and with two diameters between 

 them, occipital spine moderate, approaching to the dorsal, dorsal 

 spine with 2 or 3 fine teeth in front and 7 or 8 very fine ones 

 behind; pectoral spine, strong, flat with about 13 strong teeth; 

 maxillary cirri reach to end of ventrals ; adipose fin about ^ of total 

 length — D. 1-7, A. 10 — colour coppery brown above, yellowish be- 

 neath, with two longitudinal whitish stripes on the sides of the 

 body. Length about 4 inches. 



I have only found this Bagrus in the neighbourhood of Madras 

 where it is tolerably common. I think that it is most probably the 

 species so named by Bloch, who received it from Tfanquebar. 



Bagrus affinis. New Species. 



Very nearly allied to the last ; differs in its more depressed head ; 

 eye if any thing, smaller ; occipital spine more triangular ; dorsal 

 spine barely toothed ; pectoral spine less strongly toothed, and only 

 12 teeth; broader; head, about 3^ times in the body; maxillary 

 cirri reach to the ventrals ; colour pale blueish above, yellowish on 

 the sides, whitish beneath ; fins yellowish — D. 1-7, A. 9 — length about 

 4 inches. I procured this fish from the neighbourhood of Madras. 

 It may perhaps be Bloch's vittatus. 



■}(■ ^ ^ With short adipose, and short anal fins. 



Bagrus alhilah'is. C. V. 

 Head A\ times in length of body ; height 5 times in the same ; eye 

 one-sixth of length of head, and 3 diameters distance between the 

 two ; dorsal spine moderately strong, short, toothed ; first and se-
