A comprehensive system of malaria prophylaxis seems impossible 

 under present conditions, nor does it appear necessar}-. Anti- 

 mosquito work on a small scale should be supplemented by the cure 

 or segregation of freshly-infected cases and of plasmodia-carriers.

The danger incurred by the transportation of cattle from infected 

 to non-infected areas is discussed with special reference to the occurrence 

 of piroplasmosis, anaplasmosis and trypanosomiasis. The move- 

 ment of cattle from one hot climate to another is particularly dangerous, 

 and special care should be taken to prevent the introduction of African 

 coast fever into Madagascar, as one of the ticks transmitting it, 

 Rhipicephalus simus, is already present there. There is no danger of 

 introducing fresh diseases into hot climates from regions to the north 

 of 44*^ latitude ; but all cattle intended for export from such regions 

 should be immunised before embarkation.

This paper is complementary to the list of Anophelines alreadv 

 noticed [R.A.E., B, viii, 162] and deals with such male genitaha as 

 have not been described by Christophers [R.A.E., B, iv, 24] or of 

 which the author's observations differ from those of Christophers. 

 The latter's findings relating to Anopheles subpictus [rossi), A. vagus 

 and A . ludlowi are compared with those of the author. The other species 

 dealt with are A. hyrcaniis, Pall, {sinensis, Wied.), A. barbirostris, 

 Wulp, A. albotaeniafus, Theo., -4. umbrosus, Theo., ,4. aitkeni, 

 James, A. immactdatus, Theo. (previoush^ recorded as flavus, vSw.), 

 and A. annulipes, Wlk., var. mohiccensis , vSw. A ke}^ is given to the 

 known male genital characters of Dutch East Indian Anophelines, 

 Christophers' description being used for A^ gigas, A. janiesi, and 

 A. fidiginosus var. nivipes.

This is the first portion of a review of the means adopted in tropical 

 West Africa against various pests and diseases of stock, written with 

 the object of deducing the principles to be observed by breeders in 

 Italian Africa.
