Subfam. SCHIZOTHORACINAE. 
This subfamily is distinguished from the Cyprininae by the 
Salmonoid facies of the species, their small or degenerate lateral 
scales and the presence of an anal sheath consisting of folds of 
skin covered with greatly enlarged scales arranged in two parallel 
longitudinal rows. 
We have already commented on the two most noteworthy 
features of the Schizothoracinae, their geographical isolation and 
their superficial resemblance to the Salmonidae. It may be well, 
however, to state more precisely the characters wherein this 
resemblance consists, and those whereby the subfamily is linked to 
the Cyprininae. 
The resemblance to the Salmonidae is entirely external. It 
consists in the graceful but powerful frame of the fish, their small 
scales and usually silvery, often spotted colouration. ‘The close 
relationship to the Cyprininae is manifested in the whole structure. 
One or two important features of agreement may be noted. The 
air-bladder in both subfamilies is normally very large and is divided 
into a larger posterior and a smaller anterior region by a transverse
