INDIAN CYPRINID^. 267 



The following three species have a black spot at the base of the caudal, 

 and the dark colour of the back descends in fasciated points on the sides, thus 

 indicating a relation with the Sarcoborince ; but until the nature of this relation 

 be determined, and their habits and structure known, I place them with the 

 Cirrhins. I only know them by Buchanan's figures and descriptions * 



Spec. Cyp. morula, Buch. P. G. PI. xviii, f. 91. 



Length of the head equal to the altitude of the body, and 

 to a fourth of the length ; lips pendulous, the hinder fimbriated. 

 D.13 : P.16 : V.9 : A.8 : C.19. 



Hab. Ponds in Bengal, 



Spec. Cyp. joalius, Buch. t. 42. f. 6. /3f 



Head large and very blunt, mouth low and horizontal. 

 D.12: P.— ? V.9: A.8: C— ? 



Hab. North-eastern parts of Bengal. 



Spec. Cyp. dero, Buch. P. G. t. xxii. f. 78. 



Only two cirri. Head oval and blunt, snout prominent and 

 rough, lips smooth-edged. D.13 : P.18 : — ? V.9 : A.7 : C.19. 

 Hae. Bramaputra. 



Sub-Gen.— LABEO. 



Char. Structure and habits agree with those of the Cirrhins, but cirri are 

 wanting, or very minute. 



Obs. The last species would seem to be a Catasfomus, and the two first to 

 be very nearly allied to each other, and to differ chiefly from C. gonius, Buch. 



* To these may be added for the present Cyp. pausio, Biicli. P. G 317- t. 42. f. 4 |3. It seems 

 to differ from them merely in being witiiout cirri. 



t This sign |3, denotes that the figure lmvcii is from Biiciianan's eolleetion.
