in birds, it is stated that, at a temperature of 77° to 85° F., there is a 

 period of incubation lasting from 12 to 15 days during which the parasite 

 is present in the form of zygotes encysted in the wall of the stomach 

 of the mosquito {Culex pipiens), before the sporozoits appear.

A search has been carried on for some years for Lafont's flagellate 



in the latex of several hundreds of Euphorbiaceae in Algeria, especially 



Euphorbia peplus, E. peploides and E. helioscopia. The investigations 



were generally made in the spring, when Euphorbia was abundant, 



and only on one occasion were protozoa found in May, in the latex 



of E. peploides. This is the first time that Leptomonas davidi has been 



recorded in northern Africa, and apparently its first record from the 



latex of this species [cf. R.A.E., B, ix, 154].

On 22nd November 1919, more than 100 individuals of Ctd ex pipiens 

 were fed on a Senegalese who was known to harbour embryos of 

 Acanthocheilonema {Filaria) per stuns, the insects being removed 

 immediately afterwards to an incubator heated to 75 to 77° F. After 

 two months they were fed on a monkey {Macacus sinicus) . The result 

 was negative in spite of the fact that examination was continued for 

 eight months. Microscopic examination of the thoracic and cephalic 

 content of 20 individuals of Culex fed on blood infected with 

 A . Persians revealed no filariae. 



Only one case of filariasis contracted in Algeria has as yet been 

 recorded (in 1908), but, particularly since the war, thousands of natives 

 harbouring embryonic filariae have travelled about Algeria.

A dwarf individual of P. papatasii, Scop., is recorded from a number
