cross-section, in this respect somewhat resembling those of Austra- 
lella indica, though the feature is less marked. The average 
length of the gemmule is 0°42 mm., the average breadth 0°25 mm., 
but the difficulty in exact measurement noted in the case of 
A. indica (p. 166) also occurs with reference to them, though not 
to the same extent. The average measurements of the capsule 
are about 0°24 X0°17 mm. 
The colonies of this new variety were found on stones and 
rushes in July, 1914. ‘They exhibited among themselves, so far 
as the zoarium was concerned, a complete transition between the 
two seasonal phases of the species found in Europe. In several 
instances the freshwater sponge Sfongzlla alba, Carter had already 
begun to grow over them; by November of the same year it 
seemed to have exterminated them altogether.

For some reason all reference to this species is omitted from 
the Zoological Record. I take the opportunity to reproduce an 
enlarged photograph of one of the types, a young colony from 
Malwa Tal in the Western Himalayas.

Professor K. Ramunni Menon has sent me specimens of this 
species from the town of Madras. It thus occurs in the Main 
Area of the Indian Peninsula as well as in the Indo-Gangetic 
Plain.
