4. SPONGILLA (STRATOSPONGILLA) BOMBAYENSIS, Carter. 
Specimens from Naukuchia Tal (alt. 4,000 feet) differ suff- 
ciently from the typical form as found in Bombay and Mysore to 
be regarded as the types of a new variety for which, in the addenda 
to my volume in the Fauna of British India (p. 241), I have pro- 
posed the name pneumatica. Their most striking feature is the 
thick but irregular pneumatic coat superimposed on the gemmule 
outside the gemmule-spicules. They are also remarkable for 
possessing short vertical branches, and one specimen takes the 
form of a delicate cup attached by its. base to a twig.

Specimens belonging to this common and widely distributed 
species were taken in May in several of the lakes, in which it 
appears to replace E. meyeni, Carter, the form common in the 
plains of India. In Naukuchia Tal, the water of which is remark- 
ably clear, Mr. Kemp was able to see that they did not occur at 
depths much greater than 10 feet. Gemmules were also taken on 
the surface of Bhim Tal in October and were attributed to EL. 
vobusta' (Potts), which is probably only a variety of E. fluviatilis.
