41. Barbus inermis. 



Barbus (Dangila) inermis, Peters, Monatsber. Ak. Wiss. Berlin, 1852, 

 p. 683. 



D. 13. A. 8. L. lat. 31, L. transv. 4i./3. 



The osseous dorsal ray is scarcely stronger than the others, flexible, 

 without serrature. There are two and a half lougitucHnal series of 

 scales between the lateral line and the root of the ventral. Body 

 rather elongate, its depth being less than the length of the head, 

 which is one-fourth of the total length (without caudal). Head 

 depressed, its depth being less than its length, without snout. The 

 ei/e is more than one-fourth of the Jenr/th of the head in specimens 3 

 inches long. Snout rather obtuse. Mouth small. The origin of the 

 dorsal Jin is coiisiderahly in advance of tliat of the ventral, and some- 

 what nearer to the end of the snout than to the root of the caudal. 

 Anal narrow, deep ; caudal deeply forked. Coloration uniform. 



Tette. 



This description is made from a drawing kindly communicated to

D. 11. A. 8. L. lat. 30-^3. L. transv. 5^/?. 



The osseous dorsal ray is scarcely stronger than the others, flexible, 

 without serrature. There are two and a half longitudinal series of 

 Bcales between the lateral line and the root of the ventral. The 

 length of the head is rather more than one-fourth, the depth of the 

 body two-sevenths of the total length (without caudal). The eye is 

 one-third, or somewhat less than one-third, of the length of the 

 head, in specimens 3 inches long. tSnout i-ather obtuse. Mouth 

 small. The origin of the dorsal fin is opposite that of the ventral, 

 and midway between the end of the snout and the root of the caudal 

 fin. Anal small, low. Caudal moderately forked. A greyish or 

 blackish band runs from the eye to the caudal fin. (^Steincl.)

43. Barbus argeuteus. 



D. 11. A. 7. L. lat. 29-31. L. transv. 5/4|. 



The osseous dorsal ray is of moderate strength, its stiff portion 



being two-thii-ds as long as the head ; its serrature is not very tine. 



There arc two and a half loniiitudina] scries of scales between the
