Descriptions and figures are given of the male genitalia of the three 

 British Anophelines : — Anopheles maculipennis , Meig., A. bifurcatus,

YoRKE (W.). On Human Trypanosomiasis in Peru. — Ann. Trop. 

 Med. Parasit., Liverpool, xiii, no. 4. 15th March 1920, pp. 459-460. 



An account is given of the first recorded case of human trypanoso- 

 miasis in Peru [R.A.E., B, viii, 65]. The disease was contracted 

 in the region bordering on Brazil where the Reduviid bug, Triatoma 

 mefjista, and other vectors of trypanosomiasis exist. The trypanosome 

 in question proved to be new and is here named Trypanosoma escomeli. 



A notable feature of the case was the extreme somnolence of the 

 patient. This feature does not appear to occur in Chagas' disease 

 (due to Trypanosoma eruzi), though it is well known in African try- 

 panosomiasis in man.

 I'Evolution des Spirochetes de la Fievre recurrente chez le Pou.

The chief points relating to the evolution in Hce of the spirochaetes 

 of recurrent fever have been developed and confirmed [R.A.E., B 

 i, 70 ; ii, 132, 200], but some remained uninvestigated. In ])articular 

 it was not known where these changes take place, only the disappear- 

 ance of the spirochaetes from the digestive tract and the appearance 

 of new spirochaetes in the blood stream having been observed. It 

 was thought that the various evolutionary stages could be followed 

 to better advantage by making sections of lice fed at variable and 

 successive dates on man or monkeys suffering from recurrent fever. 



Examination of the sections confirmed the data previously obtained 

 and showed that the changes occur in the epithelial cells of the fore gut. 

 The pigmentation of these cells prevented the process of breaking-up 

 from being followed, nor was it possible to see how the new 

 spirochaetes passed from the digestive cells to the circulatory system. 



The feet of a louse are very fragile and the blood there swarms 

 with spirochaetes. It may therefore be said that an individual 

 inoculates himself with the disease by breaking the feet of the lice 

 he harbours. 



The hce used for sections were fixed with formol, treated with 

 alcohol, impregnated with silver nitrate according to the Cajal Levaditi 

 method, and then embedded in paraffin.

matique. — Arch. Inst. Pasteur, Tunis, xi, no. 3, February 1920, 



pp. 172-177, 1 plate. 



The first of the epidemics here recorded occurred among the Serbs 



brought to Bizerta in 1916 and was of little importance owing to the 



sanitary measures adopted.
