27. Nemachilus spilopterus. 



? Cobitis spiloptera, Cuv. Sf Val. xviii. p. 27, pi. 522. 

 D. 10. A. 7. V. 7. 



Body naked. Caudal fin subtruncate. Origin of the dorsal fin 

 midway between the extremity of the snout and the root of the caudal. 

 The height of the body is much less than the length of the head, 

 which is rather more than one-fifth of the total (without caudal). 

 The free portion of the tail is twice as long as deep. Snout of 

 moderate length, as long as the postorbital portion of the head. 

 Eyes directed upwards. Length of the pectoral fin about one-half 

 of the distance of its root from the ventral. Upper margin of the 

 dorsal fin oblique. Back with about eleven irregular dark cross 

 bands not descending on the sides ; a black band across the root of 

 the caudal fin. A black spot on the base of the anterior three 

 dorsal rays.

28. Nemachilus butanensis. 



? Cobitis butanensis, M^ Clell. Cah. Journ. Nat. Hist. ii. p. 586. 

 D. 9. A. 7. V. 7. 



Scales conspicuous. Caudal fin rounded. The origin of the dor- 

 sal fin is much nearer to the end of the snout than to the root of the 

 caudal. The height of the body is considerably less than the length 

 of the head, which is one-sixth of the total (without caudal). The 

 free portion of the tail is elongate, compressed, its depth being nearly 

 one-half of its length. Eye very small, nearly in the middle of the 

 length of the head. The length of the pectoral is less than one-half 

 of the distance of its base from the ventral. Upper margin of the 

 dorsal fin subhorizontal, convex. Lips ciliated. Coloration ? 



Butan. 



a. ? Typical specimen, 5 inches long. From Griffith's Collection. 



I can only conjecture that this is the typical specimen of the 

 species indicated by M'Clelland. It is from Griffith's Collection, and 

 similar in its state of preservation to other examples collected by him. 

 M'CleUand's diagnosis is so short as to be applicable to a great num- 

 ber of Loaches. 



29. Nemachilus monoceros. 



Cobitis monoceros, M' Clell. Ind. Cypr. pp. 305, 438, pi. 52. fig. 2. 



D. 12. A. 6. V. 8. 



■ Caudal fin rounded ; upper margin of the dorsal fin oblique, 



straight. The length of the head is one-fourth of the total (without 



caudal). Snout produced, with a short, blunt spine above its end. 



Body without marks ; dorsal and caudal fins with transverse stripes.
