REVIEW — TEOPICAL MEDICINE, ETC. 137 



Pinoy'* has succeeded in infecting the foot of a pigeon with a white mycetomatous Mycetoma 

 growth of human origin. Strange to say, the grains in the pigeon were black. The fungus —coiUimicd 

 was first cultivated in sweetened bouillon under anterobic conditions. 



Myiasis or, more correctly, Myiasis (Gould). This subject, as far as the human being 

 is concerned, is of special interest to medical officers in the Southern Sudan, and 

 especially in the Bahr-Bl-Ghazal Province. Some facts have alreiidy been collected 

 regarding myiasis in the Sudan {ride Second Report), but there is no doubt that a great 

 deal remains to be discovered, and Mr. King is paying special attention to this subject. 



Wellman- gives the following list of diptera known to cause human myiasis : — 



CEstridoi 

 Gastrophilus. Horses and man. 



Hypodcrma. U. bovis, man. H. dirtna, deer and man. 



Dcrnialohia. The larvfe of D. ci/anivcntris is the " Ver Maca(iue " o£ tropical America, and in man causes 

 painful boils, occasionally attacking the eyes ; also Hypodcrma bovis, reported by Scheubc. 



Sarcophagidm 



l^arcvphaija. S. carnaria, .S'. niagiiijica and .S'. rioficornis occasionally deposit their larvae in wounds of man 

 (India). A species of this genus {S. sp. near rcgidaris) is the fly used in the experiment detailed in this paper. 



iSnrcophihi. 5Ian and animals. 



Axiclnaeromyia. A. lutcola, in Angola, and another species (A. dcpressn), cause cutaneous myiasis in Natal 

 (but vide infra). 



Ochromyia. The larvae of 0. aiUhropophaga is the " Ver du Cayor," which in Senegal produces cutaneous 

 inflammation and swellings. 



Mtiscidce 



Masca. Larvae of Musca sps. occasionally arc passed in faeces or found in wounds. 



CalHphora. In intestines of man and animals. 



Compsomyia. The larvae of C. macellaria is the "Screw-worm" of tropical America. 



Liicilin. L. sericatn is the cause of " maggot " in sheep. The larvEB of several species of Lucilia have been 

 detected in wounds and ulcers in man and animals. 



AnlhoinyidcK 



Anthoniyia. The larvae of A. canicularis not seldom get into the stomach and intestines of man, through 

 eating raw vegetables. 



Hydrotwa. In the faeces of human beings. 



Homalomyia. In the intestines of man, being passed alive in the faeces. Osier gives a case of infection 

 by U. scalaris in Louisiana. 



Uylemyia. In human excreta. 



In a later paper' he supplements this, describing a case of intestinal infection by the larvae of Anthoniyia 

 desjardcnsii, the symptoms being abdominal tenderness, foul breath and nervous distress. In Angola he has 

 noticed myiasis produced by Sarcophaga africa, .S. albofasciata, S. sp. inccrt, Auchiiieromyia liiteola and an 

 unknown Muscid larva. 



Gedoelst^ has a contribution to our knowledge of the larvae of flies causing myiasis 

 in Africa. The principal, he says, are : — 



1. The Ver du Cayor, the larva of Ochromyia anthropophaga. 



2. The larva of Natal, which he says is probably that of Bengalia deprcssa (but vide infra). 



3. The larva of Cordylobia anthropophaga, Qriinberg. 



4. The larva of Lund found in the Congo Free State. The last is possibly the now well-known Congo 

 Floor maggot, the larva of Auchnicromyia luteola. 



Recent investigation goes to show that there is no definite evidence incriminating 

 Bengalia depressa. Its larvaehave been co nfounded with those of Cordylobia anthropophaga,, 

 apparently a much more important fiy. This is noted by Austen" in a paper on this fly, 

 which on the West Coast of Africa is called the Tumbu fly. It occurs in the Southern
