Macfie (J. W. 8). A Monomorphic Trypanosome of Man. — Rept.

 In a recent case of trypanosomiasis a monomorphic trypanosome was 

 found in the blood of a native of the Gold Coast which appears to be 

 intermediate, as regards its morphology, between T. vivax and 

 T. uniforme. While T. v-ivax is a very common parasite of domestic 

 animals in W. Africa, being found in no less than 76 per cent, of the 

 hump-backed cattle examined in 1914, neither T. uniforme nor T. caprae 

 has hitherto been identified in the Gold Coast. The latter has been 

 discovered in goats in the neighbourhood of L. Tanganyika, and, like 

 T. vivax, is carried by Glossina morsitans, being probably only a variety 

 of T. vivax. T. uniforme, discovered in Uganda in the blood of cattle, 

 is carried by G. palpalis. It would be a serious matter if T. vivax, 

 which is not pathogenic to monkeys, and which hitherto has been 

 harmless to man, should prove to be pathogenic, since it is widely 

 distributed, very abundant, and transmitted by the bites of G. palpalis, 

 G. morsitans, and G. tachinoides, to which the natives are constantly 

 exposed.

 Gold Coast. — Rept. Accra Ijoboratory for the Year 1916, London, 

 1917, pp. 83-86, 3 plates, 1 map. [Received 13th November 

 1917.] 



This key deals with twelve species of Anopheles indigenous to the 

 Colony and has been drawn up with a view to helping medical officers 

 in out-stations to the identification of species in the absence of reference 

 literature. 



These species are : — A. rufipes, A. squamosus, A. pharoensis, 

 A. cinctus, A. costalis, A. nili, A. rhodesiensis, A.funestus, A. marshalli, 

 A. flavicosta, A. mauritianus, A. umbrosus.

The author criticises the method of destruction of warble-flies in 

 cattle in England, where two species, Hypoderma lineatmn and 

 H. bovis, occur. Eggs are laid on the hairs of the legs or abdomen, 

 and the larva, passing down the hair, enters the body of the host and 

 completes its development in the back. The English method is to 

 attack the larva when in the back of the animal ; the author of this 

 note contends that it is preferable to sterilise the feet and abdomen 

 of the animals, by singeing or by frequent immersion in disinfecting 

 liquids, once in every four days, since that is the period of incubation 

 of the egg.
