species of C idicoides ,^ viz. that of suckins; the abdomen of mosqui- 

 toes of the genus Anopheles {s.l.), probably in order to obtain 

 mammalian blood ingested by the larger fly. The actual species 

 attacked was A. rossii and the observation was made at Port 

 Canning in the Ganges delta. 



The same habit has been attributed to a Burmese species of 

 " Ceratopogon" by Major N. P. O'G. Lalor,^ I.M.S., who found 

 it sucking blood from Anopheles fiiligtnostis, A. karwari and A. 

 ludlowi. He reports that species of this genus are abundant at 

 Kyaukpyu on the coast of Burma in August and bite human 

 beings.

Further Notes on the Habits and Distribution of 

 Limnocnida indica. — In th&Records of the Indian Museum, vol, vii, 

 PP- 399^403? Mr. Gravely and I published some notes on the 

 habits and distribution of Limnocnida indica, Annandale, based on 

 our observations last year. I wish to include in this note further 

 observations on the same subject which I made this year. We 

 then expressed the conclusion '' that in the life cycle of Limnoc- 

 nida indica there is probably an asexual hydroid stage which 

 lives attached to rocks at the bottom of deep pools, and that this 

 hydroid produces Medusae by budding from February till April or 

 May, when it ceases to do so whether the pool in which it lives is 

 flooded or not, and very possibly dies." It has been my effort 

 during the current year to find out this supposed hydroid stage. 



I began my work in October, iqr2. when the rains had nearly 

 ceased. I selected Medha as the place of observation owing to its 

 being easily accessible from Bomba}'. It was thought that it 

 would be possible to induce the hydroid to grow on stones placed 

 at different depths below the surface of the water in the pool and 

 left undisturbed for a sufficiently long time. I, therefore, visited 

 Medha towards the end of October, 1912, and arranged to have 

 four slabs of the same kind of trap as that which forms the 

 bottom and sides of the pool immersed 5, 10, 15 and 21 feet 

 below the surface of the water. The last was resting on the 

 bottom of the pool. The stones were secured by means of strong 

 coir ropes to other bigger stones which were placed on a not 

 easily accessible part of the rock in the middle of the pool. This 

 precaution was necessary to prevent meddlesome persons from 

 taking out the stones and preventing the growth of the hydroid. 

 The place was also watched continually by a peoU; whom I en- 

 gaged for the purpose. I visited the locality again towards the 

 middle of Januar}^, February and April, 1913, i.e. after 3, 4 and 

 6 months respectively. During none of these visits was I able to 

 see on the stones an}^ organism which could be the hydroid stage 

 of Limnocnida indica. On one occasion I found a few Rotifers
