The following new names are proposed : — Ciilex crinicauda for 

 C. parvus, Ta}-!., nee Macq. (this species is not synonymous with 

 C. vishiui, Theo.) ; C. taylori for Leucomyia annulirostris, Tayl., 

 nee Culex annulirostris, Skuse ; and C. basicinctus for Leucomyia 

 annulata, Tayl., nee Culex annulatus, Schrank. 



Further examination shows Culex albigenn, End., to be synonymous 

 with C. ventrilloni, Edw. ; C. auritaenia. End., with C. quasigelidus , 

 Theo. ; Lophoceratomyia curtipalpis, Edw., with Culex {L.) jenseni, 

 Meij. ; and Rachisoura sylvestris, Theo., and Mimeteomyia hilli, 

 Tayl., with Rachisoura fiUpes, Wlk. ; while Stegomyia quasiornata, 

 Tayl., should be placed in the genus Rachionotomyia.

The larvae of certain Anophelines, particularly A. maculatns, 

 A. karivari and A. aitkeni, occur in streams so swift that their presence 

 would appear impossible without some mechanism that enables 

 them to maintain their position in the water. A pair of dorsal tail 

 brushes, terminated by booklets, provides this mechanism ; and there 

 is a counterpart, in the case of certain pupae, in the form of a pair 

 of hooks terminating the paddles.

 logical Department for Year ended 31st December 1920, Entebbe, 



1921, 20 pp. 



Malaria is very common among the monkeys in the Uganda labora- 

 tory, the parasites resembling the benign tertian type. A natural 

 infection of a Plasmodium in a chimpanzee is interesting in view of 

 the recent experiments of Mesnil and Roubaud [R.A.E., B, viii, 217]. 



Experiments are in progress dealing with the affinities of the lake- 

 shore trypanosomes and their development in Glossina palpalis. 

 Feeding of 3,029 wild flies from around Entebbe on four monkeys 

 resulted in one of the latter developing the lake-shore trypanosome. 



Four cases of sleeping sickness were reported from a village on the 

 northern shore of Lake Kwania, and in consequence a tour of the 

 district was undertaken, in the course of which 3,258 natives were 

 examined without any case of the disease being detected. A few 

 individuals of G. palpalis were obtained along the Kwania shores, 

 and it is considered that the sporadic cases of trypanosomiasis in that 

 region are due to their agency. There is no evidence that any tsetse 

 other than G. palpalis is the vector of human trypanosomiasis in 

 Uganda ; actual experimental examination of the trypanosomes carried 

 by the inland bush flies could not, however, be made. Clearing 

 should reduce the already small danger of human infection, and the 

 conditions are not such as to justify the fear of an epidemic.

 pp. 15-18. [Received 14th June 1921.] 



A review is given of the conditions with regard to sleeping sickness 

 and the occurrence of Glossina in Tanganyika territory according to 

 German records. The present position is not very clear, indicating
