The structure of the gemmules of this species differs considerably from that in any other known species of the genus, in which these structures are usually adherent and devoid of a true pneumatic coat. In some of the gemmules before me this coat measures in thickness about 1/9 of the total diameter of the gemmule. C. caunteri is the first species of Corvospongilla to be found in the Indo-Gangetic plain.

Genus HYDRA (p. [147]).
25. Hydra oligactis (p. [158]).
Mr. Kemp found this species common in Bhim Tal in May. His specimens, which were of a reddish-brown colour in life, appear to have been of more vigorous constitution than those taken by Major Stephenson in Lahore. Some of them had four buds but none were sexually mature.
PART III.
Genus FREDERICELLA (p. [208]).
28. Fredericella indica (p. [210]).
This species is common in some of the Kumaon lakes, in which it grows, at any rate at the beginning of summer, much more luxuriantly than it does in the lakes of the Malabar Zone in autumn, forming dense bushy masses on the under surface of stones, on sticks, &c. The vertical branches often consist of many zoœcia. Mr. Kemp took specimens in Malwa Tal, Sath Tal, and Naini Tal (alt. 3600-6300 feet).
Genus PLUMATELLA (p. [212]).
