During a recent expedition carried out by Dr. W. K. Blackie and Mr. W. A. McDonald in Southern Rhodesia, large numbers of the snail Bulinus tropicus were collected for living storage in aquarium tanks in the Medical Zoology Division of the London School of Hygiene and Tropical Medicine. They were collected about the 20th February, 1931 and were brought to London on the 30th March and were distributed amongst several separate tanks. Some five weeks later some of the snails were overtaken by a curious sickness which gradually but rapidly spread to the rest and within a fortnight of their first appearance, the characteristic symptoms were present to a greater or less degree in almost every one of the snails, which numbered several hundreds. The sickness proved fatal in many cases and towards the end of three weeks the mortality was nearly 50 per cent. Thus it appeared likely that the whole collection would eventually be destroyed when the epidemic, as it seemed to be, spent itself with surprising suddenness and the remaining snails made a rapid recovery.

While investigating the Anophelini of Southern Rhodesia in connection with the research on blackwater fever conducted by the London School of Hygiene and Tropical Medicine, an undescribed variety of Anopheles funestus, Giles, was taken in the dry season. Nine males and eight females were collected from May to August 1927, near Shamva, and one male and one female in July 1928, in the Fungwi Native Reserve. All were caught out-of-doors except two females, one of which was taken in a shed constructed of grass and the other in a native hut. The remainder were taken in close association with the earth; in surface drains, caves and crevices in rocks. No specimens were taken in or near European habitations, but all in undeveloped country. No adults were bred out, so that the following description is based on individuals captured “wild.” The larva is unknown.

The material listed here was obtained by Dr. W. K. Blackie and Mr. W. A. McDonald during a helminthological expedition from the London School of Hygiene and Tropical Medicine to Southern Rhodesia in 1930–31. The writer is indebted to Professor R. T. Leiper for the privilege of examining and reporting on this collection of parasites. The domestic animals in question are sheep, goat, pig and cattle and although they appear to have produced no forms new to science, it is believed that the publication of this collection, inasmuch as it appears to be the only one of its kind from Southern Rhodesia, is a contribution to our knowledge of an important parasitic group.

The following material was sent to the Department of Helminthology of the London School of Hygiene and Tropical Medicine in three groups; two lots coming from Mr. Aneurin Lewis, of the Veterinary Research Station at Kabete, Kenya Colony, and the third lot from the Director of Veterinary Services, Uganda. For this latter, the writer is indebted to the Imperial Bureau of Agricultural Parasitology. The major part of the material was placed at his disposal by Professor R. T. Leiper, F.R.S., to whom he wishes to express his sincere thanks.

Kala-azar is a parasitic disease that was endemic in India, parts of Africa and China. During the first half of the twentieth century, developing means of treatment and identification of the host and transmission vectors for this deadly disease would be the subject of transnational research and controversy. In the formative period for this research, two Canadian Medical missionaries, Drs. Jean Dow and Ernest Struthers, pioneered work on Kala-azar in the North Henan Mission. The great international prestige of the London School of Tropical Medicine and the Indian Medical Service would stand against recognition of the clinical discoveries of missionary doctors in remote North Henan. It was only after Struthers forged personal relations with Dr. Lionel. E. Napier and his colleagues at the Calcutta School of Tropical Medicine that there was a meeting of minds to promote the hypothesis that the sand fly was the transmission vector.

Being engaged on a complete revision of the genus Inermicapsifer Janicki (1910), we had occasion to examine some material from the Helminthological Department of the London School of Tropical Medicine. This material was kindly placed at our disposal by Prof. R. T. Leiper, F.R.S., to whom we here tender our sincerest thanks. We are also indebted to Prof. O. Fuhrmann for his useful advice and criticisms.

New West

In describing the following new species from West Africa, some words of explanation are needed as to the generic names used. In the first place, it is necessary to say that the writer follows Messrs. Dyar and Knab in considering that most of the genera into which Meigen's genus Anopheles has recently been split up are not genera in any accepted sense, and should sink under the old name Anopheles. Provisionally, however, Stethomyia, Chagasia, Calvertina and Bironella are considered as distinct; as none of these genera are African, this will not affect the present paper. Lieut.-Col. A. Alcock, of the London School of Tropical Medicine, has kindly allowed me to see the manuscript of a paper on the classification of Anopheles, which he is about to publish in the Annals and Magazine of Natural History, and I have been able to concur entirely with his views; he recognises only five sub-genera of Anopheles, the sub-genus Nyssorhynchus including all those species with flat scales on thorax and abdomen, i.e., the genera Nyssorhynchus, Cellia and Neocellia of Theobald's Monograph.
