This species is also without suborbitar spines, and in my opinion is nearly 

 allied to S. suhfusca ; the ventrals are however round, and the rays of the 

 dorsal are marked on the middle with a brown spot. I cannot find this spe- 

 cies referred to in the Gangetic Fishes, although it is figured in Buchanan's 

 collection. 



So many divisions of the Loaches have been proposed, and so many names 

 to designate those divisions, that I feel some doubt in recommending the 

 generic term Hymenphysa^' for the following three species, which are dis- 

 tinguished from all others by the presence of an abdominal natatory bladder, 

 separated into lobes by a longitudinal septum. 



Etym. ('(^(c)', a membrane, and (^wan. an air-bladder.
