The Potential Danger of Anopheles Leucosphyrus in Assam

as harmless, may in certain localities prove an important carrier of malaria in Assam. Although the number of dissections are small, nevertheless the comparative statement of sporozoite indices of A. leucosphyrus and A. minimus published by these authors is sufficiently illuminating in regard to the susceptibility of the former to plasmodial parasites of man.

Our experience in a locality at the foot of the Naga Hills near Dimapur suggests that under certain circumstances, which are insufficiently known, A. leucosphyrus may prove potentially dangerous. This place was visited by us during the rainy season in connection with a severe epidemic of malaria (some
