Introduction. 



The notes embodied in this paper are based primarily on 

 collections made in the course of a tour in the Satara and Poona 

 districts in February and March, 1918. The chief localities at 

 which these collections were made were Medha in the Satara dis- 

 trict (alt. ca. 2,000 feet) and Khandalla in the Poona district (alt. 

 ca. 2,500 feet). The former place i? situated on the river Yenna 

 or Vena, a tributary of the Kistna or Krishna, in a valley among 

 the easternmost spurs of the Western Ghats ; the latter on the 

 hillside about a mile and a half east of the well-known pass Bhor 

 Ghat. From Medha the Zoological Survey of India already pos- 

 sessad large collections of aquatic invertebrates made by Dr. F. H. 

 Gravely and Mr. S. P. Agharkar. 



My main object in visiting Medha was to obtain further 

 information about the freshwater medusa Limnocnida indica, which 

 was originally discovered there by Mr. Agharkar; while Khandalla 

 was selected as a suitable spot at which to study the fauna of the 

 small mountain torrents of the Bombay Ghats. It is a locality 

 well known to conchologists as the home of the interesting genera 

 Lithotis (Succineidae) and Cremnoconchus (Littorinidae). 



So far as Ltmnocnida was concerned the results of my tour 

 were purely negative, but even so they are not devoid of interest, 

 for they prove beyond doubt that the medusa must have a fixed
