Habitat. Affghanistan. In the Helmund there is a variety of this 

 species, (No. 74,) with a small dorsal spine, and the lateral line less 

 conspicuous, which will probably prove to be distinct. Griff. (Coll.)

Observations.— -The intestines in Schizothorax vary from

 species only being known to take bait and worms freely, and 

 their intestines are always found to be loaded with a dark 

 pulpy matter. Griff, MSS.

 The upper lip soft and continuous, with a reflected mammi-
