204 Records of the Indian Museum. [Vol. XXII, 



The open pores, noticed in the preceding species, are present 

 all over the head and are continued along the lateral line as well. 

 There is a well-marked prominence in the middle of the upper jaw 

 and the lower lip is interrupted in the middle. 



The lateral line is crossed by 13 short, black vertical bands. 

 Above the lateral line the body is marked by a characteristic reti- 

 culum formed by numerous dark bands and blotches. The under 

 surface of the head and body is pale olivaceous. There is a deep 

 black bar at the base of the caudal fin and two dotted bands across 

 it. The dorsal fin is marked by two bands and a black spot at 

 the base of the first few rays. The remaining fins are spotless or 

 in some examples very indistinctly marked. 



The specimens of Nc/imchilus prashadi were obtained in Tho- 

 nagpal tank and in Thoubal and Sikmai streams. Of 74 specimens, 

 40 are males and the rest females. 



I have great pleasure in associating this fish with the name 

 of my friend Dr. Baini Prashad, Assistant vSuperintendent, Zoolo- 

 gical Survey of India, who has given me every possible encourage- 

 ment in my work in the Museum.

The individuals of this species from different localities show 

 considerable variation in colour. Those from the lyoktak Lake are 

 dirty yellowish-orange, shot with minute black dots all over. 

 These dots are aggregated to form b — ii transverse bands on the 

 body. A similar ariangement of dots forms a black blotch over 

 the shoulder. The upper portion of the iris and the head are 

 stained with black. In the young individuals the transverse bands 

 are absent. The specimens collected in streams are lighter in colour 

 and do not show any black dots, though in some cases the trans- 

 verse bands are well marked.

There are altogether three specimens of the species, two of 

 which were captured in Dhanashori stream and one in a small 

 pool in thick jungle near Dimapur, Assam. In colouration the 

 fish agree with Day's description of the Assamese specimens. 



This species is said to occur all over India and Burma, )iut I 

 did not get a single specimen of it in Manipur.
