316 THE ZOOLOGIST. 
The first part is devoted to an elaborate and fully illustrated 
“Revision of the non-Combed Eyed Siphonaptera,’ by Dr. Karl 
Jordan and the Hon. N. C. Rothschild. 
In the Report of the Board of Scientific Advice to the Govern- 
ment of India, 1907, Dr. Annandale has contributed some interesting 
facts as to the progress of Indian zoology during that year. One of the 
most important features is the Survey of the Invertebrate Fauna of 
Stagnant Water. Additional collections of microscopic freshwater 
animals have been made in Calcutta, Eastern Bengal, the United 
Provinees, and the Simla Hill States by the Superintendent and the 
Museum Collector, and have been sent for determination to Prof. von © 
Daday, of Buda Pesth, while a large number of specimens of aquatic 
and semi-aquatic insects have been obtained from the same districts. 
The aquatic Hemiptera have been sent to Mr. W. L. Distant for 
description in a supplement to his volumes on the Order in the 
‘Fauna of British India,’ the Chironomide (Midges) to the Abbé 
Keiffer in Germany, and the Neuroptera to Prof. Needham in the 
United States, while arrangements are being made regarding the 
working out of the aquatic beetles in France. The Anopheline 
among the mosquitoes have been identified in the Museum, while the 
Culicine will be identified in England by Mr. Theobald. 
The work has not, however, been confined to the collection of 
specimens and their transmission abroad for identification, for in- 
vestigations have been made into various obscure points in the struc- 
ture and biology of the freshwater sponges (of which several new 
species have also been described), such as the process of budding, 
the nature of the inhalent pores, commensalism, and the production 
of gemmules. 
Even more important than the fauna of freshwater ponds is that of 
the brackish pools in the Ganges delta, especially in the neighbourhood 
of Port Canning. Large collections have been made in such ponds, 
and it is hoped shortly, with the aid of the Rey. T. R. R. Stebbing, 
Dr. J. G. de Man, Mr. HE. A. Smith, Mr. W. L. Distant, Col. Godwin 
Austen, M. Régimbart, and Prof. von Daday, to publish a complete 
fauna. It has been possible, thanks to the work done nearly forty 
years ago by the late Dr. F. Stoliczka, of the Geological Survey of 
India, to trace a very rapid and extraordinary change in the structure 
and habits of a sea-anemone (Metridiwm schillercanum) which occurs 
in certain brackish ponds of recent origin at Port Canning, while the 
other elements in the fauna to which this remarkable species belongs 
have proved of great biological interest.
