A Short Note on Hydra oligactis, Pallas. 
On the oceasion of a recent visit to Ludhiana (Punjab) I found 
a few specimens of Hydra oligactis, Pallas, in a small pond full of 
the pond-weed Potamogeton pectinatus, Linn. One of these speci- 
mens of Hydva was rather peculiar in having seven tentacles. 
Ir. Annandale in his account (fauna of British India, Freshwater 
Sponges, Hydroids and Polyzoa, p. 159) says that he has not seen 
any Indian specimen with more than six tentacles, while quite a 
large number of specimens that I have examined from Lahore and 
Ferozpore had usually four, and in exceptional cases five tentacles. 
The manner of capturing food was also observed, it exactly 
corresponds to Dr. Annandale’s account.(Fauna, p. 152) of Hydra 
vulgaris phase ortentalts Annandale. ‘The food consisted of very 
young individuals of the Aphis Szphocoryne nymphae which was 
infesting the plant in large numbers.

BATRACHIA. 
The larva of Rhacophoras pleuarostictus, Boul. (Fauna, p. 479.) 
The tadpoles, which were collected in Coorg, presented some 
difficulty in the matter of identification. This was due to the 
absence of any four-legged forms in the collection; but Dr. N. 
Annandale, who had received a fine collection of tadpoles from 
Cochin, has by a process of exclusion identified them as the larvae 
of Rhacophorus pleurostictus; as he has pointed out, the character 
of the feet at onee excludes these larvae from the genus Rana. 
The head and body are moderately flattened above and broadly 
oval, ventrally convex. The snout is rounded. The length of 
the body is to the breadth as 7:5. The body is finely pitted 
above, perfectly smooth below; but in specimens in which the 
hind limbs have not sprouted it is smooth above as well as below. 
Two conspicuous oval parotoids are present. 
The eye and nostril are both small, dorsally placed, by no 
means prominent. The nostril is very small, directed almost 
anteriorly, equidistant between the eyes and the tip of the snout. 
The internasal space is twice the interorbital. 
The mouth is subterminal, small. Its greatest width is only 
slightly greater than the interorbital space (as 7:5). The lower
