 Euphorbes et sur leur Culture. — Bull. Soc. Path. Exot., Paris, 

 XV, no. 5, 10th May 1922, pp. 299-303, 1 fig. 



The culture of trypanosomes from Euphorbia has been made success- 

 fully on plates of Noller medium. Examination of the cultures 

 showed a close relation between these trypanosomes and other large 

 parasites, round or ovular in shape and resembling Amoeba, found with 

 them. There is probably an endocellular stage in the development 

 of the trj^panosome.

Bidl. Soc. Path. Exot., Paris, xv, no. 5, 10th May 1922, 



pp. 305-310, 12 figs. 



Descriptions of both sexes and of the larva of Bironella gracilis, 



Theo., are given, from specimens taken in the north of New Guinea. 



The breeding-places were in the virgin forest and comprised pools of 



swamp water with a muddy bottom. The larvae were easily 



captured, as they are not active. Though the distance to the forest 



was small, no specimen of this Anopheline was taken in the huts 



forming the camp, where, on the other hand. Anopheles pnnctulatns 



var. moluccensis, Sw., was abundant. B. gracilis does not appear to 



have been a carrier of malaria in the camp.

Soudan. — Bull. Soc. Path. Exot., Paris, xv, no. 5, 10th May 



1922, pp. 320-331, 1 map. 



An outbreak of recurrent fever that began in May 1921 in the 



French Sudan is described. An examination of 3,735 of the 



inhabitants of 13 villages on the Niger failed to reveal the spirochaete,. 



nor was Ornithodorus moubata found. The disease was imported by 



native troops from Syria or Morocco, and its spread is easily accounted 



for by lice, Pediculus himianus [vestimenti), found in the clothing of 



nearly all the natives. The measures taken included the establishment 



of disinfection and isolation stations.

 Technique.] — Centralbl. Bakt., Paras., Infektionskr., Jena,

In November 1921 very few flagellates were found in examples of 

 the bug, Pyrrhocoris apterus, which were infected with Herpetomonas 

 Pyrrhocoris. The gut contained spherical cysts with either granular 

 protoplasm or spindle-shaped sporozoites. Some of the latter were 

 free and were noticed, in one case, in the oesophagus. The author 

 suggests that H. pyrrhocoris derives from forms found by him in 

 Colchicuni atitnmnale, and that these cysts are the agents diffusing the 

 parasite in plants. 



Attempts were made to infect vertebrates, such as fish, frogs, mice and 

 rats, with H. Pyrrhocoris, but no flagellates resulted ; in a few cases 

 leishmaniform bodies occurred at the inoculation point. Inoculations 

 with H. melophagi gave similar results. The matter is of great interest 

 in connection with the hypothesis that these parasites are derived 

 from Cnidosporidia of insects. 



The author states that Calliphora erythrocephala can not only 

 hibernate but can oviposit in winter.
