252 Records of the Indian Mu^.eum. [Voi,, VIII, 



Colour. — The body is brown, with a broad black band run- 

 ning along the middle of each side beginning from the corner of the 

 mouth passing through the middle of the eye and body to the 

 root of the caudal ; the band extends to the middle of the caudal 

 fin in two attenuated black lines. There is also a black line on 

 the dorsal side from the occiput to the root of the caudal , and the 

 margin of each scale is spotted with minute black points. The 

 fish resembles Rashora rasbora (H.B.) more than Rasbora daniconia 

 (H. B.), except in having the middle band distinctly black, in- 

 stead of being merely a faint streak. 



The new variety differs from both these species in having the 

 lateral line incomplete, in the number of scales in front of the 

 dorsal fin and in other particulars, including the proportions. 



One specimen, type of the new variet3\ numbered F. ^-^^ in 

 the Museum register, was found at Kobo, 400 ft. : its length 

 with caudal is 47 mm. Three specimens were taken at Dibrugarh. 



Danio aequipinnatus (McClell.). 



Yembung, alt. iioo ft. Twelve specimens. 



The broad black band extends along the middle line to the 

 caudal fin. Another damaged specimen which was received with 

 this lot probably belongs to the same species but is a deeper fish. 



Fam. SILURIDAH. 



Amblyceps mangois (H.B.). 



Four specimens were found in a stream south of Yembung. 

 One specimen is dark grey, the rest are dark brown, the usual 

 colour of the species. 



Clarias assamensis, Day. 

 Dibrugarh. 



Exostoma davidi, Sauvage. 



Between Rotung and Renging. Two specimens only. 

 The pectoral fins reach the root of the ventral. 

 This species has previously been reported onlv from Eastern 

 Tibet. 



Exostoma labiatum (McClell.). 



Egar stream, between Rotung and Renging, six specimens. 

 Previously reported from the Mishmi hills. Eastern Assam and 

 Burma. 



Of the mandibular barbels the two internal ones, which are 

 very small, are attached to the margin of the middle lobe of the 

 overturned lower lip, but the outer pair are fairly long, attached 

 to the skin of the isthmus outside the margin of the outer lobes. 

 There is a broad dark brown band along the middle line from the 

 operculum to the root of the caudal.
