shot by a member of the Commission were sent to a point on one 

 of the main paths, from where a motor cyclist carried them to the 

 camp at Easu. On arrival the blood was at once injected into a 

 goat, a monkey and a dog. Among the 180 animals procured 

 from the heart of the Nyasaland Sleeping Sickness area 57 (or 

 31'7 per cent.) were found to harbonr pathogenic trypanosomes. 

 The species of the latter found are T. hrucei vel rhodesiense 7"8 

 per cent., T. pecorum 14'4 per cent., T. simiae 1'7, T. caprae ll'l, 

 and T. ingens (not pathogenic) 1"7. The animals infected are 

 waterbuck, haartebeeste, reedbuck, duiker, buffalo, hyena, 

 warthog, eland, oribi, kudu, and buslibuck, of which the first 

 four are dangerous neighbours to man find the others to cattle, 

 goats and sheep. The wild animals should not be allowed to live 

 in ' fly-country ' and game laws restricting their destruction 

 should be removed. This only refers to wild animals living in 

 fly-areas, no pathogenic trypanosomes having been found by the 

 Commission in the blood of animals living in fly-free areas.

Tlie Commission did not meet with Trypanosoma vniforme or 

 T. wva.r in Nyasaland, possibly owing to the absence of Glosswa 

 palpalis. G. morsitans, especially in the neighbourhood of 

 Kasu, are heavily infected with T. caprae, the development of 

 which is restricted to the proboscis. T. caprae is not of patho- 

 logical importance in oxen, but is fatal to goats and sheep. About 

 10 per cent, of wild game (reedbuck, waterbuck, bushbuck and 

 eland) in the Nyasaland Sleeping Sickness area are infected, the 

 carrier being invariably G. moraitans. Monkeys, dogs and the 

 smaller laboratory animals are immune to T. caprae.

This paper deals only with the Pangoniinae, and is almost 

 entirely syvstematic. Fifteen species were obtained, all from the 

 Katanga district, Pangonia Inikamensis and Rhinomyza rodJiaini 

 being described as new. Several alterations of names are 

 suggested in connection with species previously described by 

 Mr. E. E. Austen. 



[Mr. Austen is of opinion that not one of these proposed changes 

 is justified, a view in which the present writer concurs. — Ed.].
