Of all the hill stream fishes with which I am personallv 

 acquainted, this species has the widest range. ^McClelland (op. 

 cit.) described it for the first time from the " Kasyah mountains," 

 Day ' recorded it from the Darjiling District and Chaudhuri''* 

 extended its range to the Abor Hills. Vinciguerra' found some 

 specimens of this species in Fea's collection from Khakhyen 

 (Kachin) Hills and Chaudhuri (op. cit.) has recently recorded it 

 from Upper Burma. It is interesting to find that a fish so highly 

 specialized for life in rapid running waters should be distributed 

 over so wide an area. 



The only specimen in Air. Shaw's collection measures 75 mm. 

 including the caudal fin. It was procured by him in the Reang 

 River at an altitude of 2000 ft. in the Darji'ins; District.

There is only one specimen of this species from the Sivoke 

 River (alt. 500 ft.) in the Darjiling District. It measures 68 mm. in 

 length without the caudal fin and is a lipe female. The eggs 

 are large and I have been able to count about 36 in this specimen. 

 The diameter of the mature egg was found to be 2'2 mm. 



This species is widely distributed iri the fresh waters of Northern 

 India and Burma and usualh- occurs along the bases of the hills.

Erethistcs elongata has hitherto been known from a single spe- 

 cimen found in " a stream near the Garraw Hills." Day in his 

 later works gives the Naga Hills, probably in error. Mr. Shaw's 

 example was procured in the Mahanadi River near Siliguri, at the 

 base of the DarjiHng Himalayas ; it is 50 mm. in length without 

 the caudal fin and is longer than the type-specimen figured by 

 Day. I give below the measurements of the two specimens for 

 comparison.
