T. simiae, takes place at first in the gut, afterwards passing forward 

 into the labial cavity and finally into the hypopharynx. The final 

 stage of development occurs only in the hypopharynx, where the 

 trypanosomes revert to the " blood form " and flies become infective.

(Captain D. P.) & Bruce (Lady). Trypanosomes found in Wild 



Glossina morsitans and Wild Game in the " Fly Belt " of the Upper 



Shir6 Valley.— /6MZe?H, pp. 38-41 . 



The trypanosomes found in wild Glossina morsitayis and wild game 



of the Upper Shire fly area are identical with those found 100 miles 



farther north in the Proclaimed Area. The trypanosome causing 



disease in man in Nyasalaiid {T . brucei vel rhodesiefise) is frequently 



met with, so that it is probable that cases of this form of sleeping 



sickness will be found among natives of this district. 



— — . The Food of Glossina morsitans. — Ibidem, pp. 41-42. 



The food of Glossina morsitans consists mainly of mammalian blood 

 (99 per cent.), chiefly from species of antelope, and what appeared 

 to be avian blood (1 per cent.) There is no difference in the feeding 

 habits of the sexes. The flies probably feed once in five or six days. 



. Infectivity of Glossina morsitans in Nyasaland during 1912 



and IQiZ.— Ibidem, pp. 43-48. 



This paper gives a rough standard of the proportion of infected to 

 non-infected tsetse-flies in an ordinary fly area where wild game 

 abounds. In 1912, 6" 53 per cent, of the G. morsitans found in the 

 " Proclaimed " or Sleeping-sickness area, Nyasaland, were infected 

 with pathogenic trypanosomes ; in 1913, 8-58 per cent.

 London, xciii, no. 2336, 6th August 1914, p. 584. 

 This letter gives some notes on the Haemaproteus of the Indian 

 pigeon. These birds have been found to be heavily infested both 

 with this blood parasite and with Lynchia, and it is stated that there 

 is strong evidence that the praeter-vertebrate hfe-history of the 

 Haema'proteus of the Indian pigeon agrees with that discovered by 

 Ross for the Proteosoma of the Indian sparrow and for the malaria 

 parasite, the intermediary in the case of the Haemaproteus being 

 a Hippoboscid fly of the genus Lynchia.

 verrucarum as indicating the Reservoir of Verruga. — Science, New 

 York, xl, no. 1023, 7th Aug. 1914, pp. 212-214. 



Further facts bearing on the relations between Phlebotomus and 

 hzards or other reptiles are recorded. Blood smears made from small 

 rock lizards of several species from various locahties in Peru showed 

 rod and granule bodies exhibiting the identical morphology of the 

 Bartonia bodies associated with verruga. The localities where the 

 lizards were taken w^ere well within the verruga zone with the exception 

 of one, Chosica Canyon, just outside it. Guineapigs injected with 

 the blood of lizards which were infected died with typical verruga
