W. Ghats. A record of ‘‘ Lophopus’’ from Madras may actually 
refer to this species, statoblasts of which have been found in 
German East Africa. A race (davenporti, Oka) occurs in Japan 
and is distinguished by the stronger development of the hooked 
processes at the ends of the statoblasts. 
GEOGRAPHICAL DISFRIBUTION TORTIE SP EGiMes: 
The following list shows practically all that is known of the 
distribution of the sponges and polyzoa that have been found in 
the Kumaon lakes, at any rate so far as India is concerned. It 
would seem to provide evidence that the aquatic fauna of the 
Malabar Zone! is less restricted than it at one time appeared to 
me. Recent investigations, however, undertaken in different parts 
of India, prove that the African element which is so marked a 
feature of that fauna is more widely distributed in India than was 
at first realized. In particular, a species (a somewhat peculiar 
species, it is true) of Corvospongilla has been found in the Ganges 
valley,” while both Fredericella indica and Plumatella tanganyikae 
have been discovered in the main Peninsular Area of India. It is 
noteworthy that the Gangetic Corvospongilla differs from its 
congeners in having free statoblasts provided with a_ well- 
developed pneumatic layer, but a species of the genus more typical 
in this respect (C. ultima)* has also been found at Tanjore far to 
the east of the Western Ghats.
