Walker (E. M.). Wohlfahrtia vigil (Walker) as a Human Parasite 

 (Diptera, Sarcophagidae).— //. Parasitology, Urbana, III., vii, no. 1, 

 September 192U, pp. 1-7, 2 plates. 



Larvae of Wohlfahrtia vigil, Wlk., here described, have been extracted 

 from boil-hke sores on an infant in Toronto. A second case is recorded 

 in which the parasite is considered to be identical. The larvae were 

 subsequently fed on raw beef, ^nd under laboratory conditions they 

 disappeared into the soil for pupation by 29th June. The adult 

 flies emerged about 18th July. 



Fantham (H. B.) & Porter (A.). On the Natural Occurrence of 

 Herpetomonads (Leptomonads) in the Blood oi a Fish, Dentex 

 argvrozona, and its Significance. — //. Parasitologv, Urbana, III., vii, 

 no."l, September 1920, pp. 16-22, 1 plate. 



The flagellate, Herpetomonas denticis, sp. n., here described, was 

 found in the blood of a fish, Dentex argyrozona, near Cape Town. 

 This is an important discovery in view of the relation between 

 Herpetomonads and Leishmania. 



Leishmaniases of mammals are caused by the introduction of 

 Herpetomonads, which are parasites of invertebrates such as insects, 

 into vertebrate hosts. 



Report of Conference on Sleeping Sickness, held at Pretoria, 9th March 



1920.— [/w/ow of S. Africa Dept. Public Health. [MS. received 

 from Colonial Office, 23rd October 1920.] 



This Conference was called in connection with the recently reported 

 southward extension of sleeping sickness, and in particular to consider 

 the advisability of, and precautionary measures necessary in, the 

 introduction of native labour into Natal from the country between 

 the Limpopo and the Zambesi. 



The species of Glossina at present found in Zululand were stated 

 to be G. pallidipes, G. brevipalpis and G. austeni, the species of tr\'- 

 panosomes being Trypanosoma brucei and T. pecorum. It is possible 

 that more than one species is at present included under the name of 

 T. brucei.
