1910. ] B. L. CHAUDHURI: A new species of Nemachilus. 185 
Two specimens (of which one is a sexually mature male 
measuring 7°5 cm.) were obtained by a Museum collector in a 
small stream at Cheriyadhang near Kathgodam and one at Jaulasal, 
in the Naini Tal district (U. P.), at the base of the W. Himalayas. 
Seven specimens were collected by Mr. Mackenzie from the Jharai 
and the Jamwari Nadi near Siripur in the district of Saran 
(Bengal), and two specimens (the bigger being a sexually mature 
female measuring 7°4 cm.) were obtained by Mr. Walker from a 
jhil at Purnahia (P. O. Ghorasan) in the district of Champaran. 
There is some superficial resemblance between this new species 
and N. rubtdipennis, which is reported only from Tenasserim 
(Burma), and the type of which is in the Indian Museum collec- 
tion. From N. rubidipennis the new species differs in many 
important characters, especially in the shape of the head; also in 
the number of fin rays, shape and markings of caudal fin, propor- 
tional lengths of barbels and in several other particulars.
