barbel is contained twice in the length of the head in N. pleuro- 

 taenia, three times in N . nigromaculakis , hut in the new species 

 only If times. Scales in A', pleuroiaenia are minute and thorax 

 naked, in N. nigra maculatus scales are very small, not imbricate, 

 and both thorax and abdomen naked, in the new species the scales 

 are minute and not imbricate but both the thorax and abdomen 

 are covered with scales. In N. nigromaculatus the lateral line is 

 altogether absent, in the new species it is present but incomplete. 

 In N . pleuroiaenia the anterior root of the dorsal fin is equidistant 

 from the anterior nares and the root of caudal, in N . nigromacu-- 

 laius, from middle of eye and base of caudal, whereas in the new 

 species it is equidistant from the posterior edge of the orbit and 

 the root of caudal.

Br. vi; D. I 7; P. 9; V. 6; A. II 10; C. 17. 



Length of head 3 — 31, height of body 3|, length of middle 

 caudal rays 9, length of terminal caudal rays 3|-, the distance 

 of cloacal opening from the root of caudal fin 2| and the length 

 of the base of adipose dorsal fin 3 times in the total length (with- 

 out caudal). 



Shape. — The limiting line of the snout meets the line from the 

 root of the dorsal spine in front over the eyes in an obtuse angle. 

 From the point of attachment of the dorsal spine, which is the 

 highest point in the profile, it slopes down to the anterior root of 

 the adipose dorsal from which point it continues almost in a 

 straight line to the root of the caudal. The ventral profile is a 

 convex curve from the lower jaw to the anterior root of the anal 

 fin from which point it is concave. 



Eyes. — 31 — 4^ diameters in the length of head, i^ to i| 

 diameters in the length of snout and i|- to if in the interorbital 

 distance ; length of snout 3 times and the interorbital distance 2^ 

 times in the length of head.
