662 Indian Cyprinidoe. [August, 



Spec C. gonius, Buch. P. G. t. 4. f. 82. 



Scales minute; snout muscular and perforated by numerous mucous 

 pores. D.15 : P.17 : V.9 : A.7 : C.19. 

 Hab. Bengal and Assam. 



Spec. C. nancar, Buch. P. G. p. 299. 



Sub-operculum rudimentary, and concealed beneath the integuments 

 D.20 : P.18 : V.9 : A.8 : C.19. 



Hab. North-eastern parts of Bengal. 



" The following three species have a black spot at the base of the cau- 

 dal, 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 struc- 

 ture 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. 

 Hab. 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 Catastomus, and the two 

 first to be very nearly allied to each other, and to differ chiefly from 

 C. gonius, Buch. in being without cirri. They correspond with the 

 species named by Buchanan, Cyp. curchius, C. cursa, and C. cnrsis, 

 but I cannot altogether reconcile them with his descriptions ; they ap- 

 pear to me to be varieties resulting from domestication. 



* To these may be added for the present Cyp. pausio, Buch. P. G. 3.17. t. 42 f. 4 B. 

 It seems to differ from them merely in being without cirri, 

 f This sign j3 ? denotes that the figure given is from Buchanan's collection.
