4.—Relationship to Malaria. 
It is now well known that it is not every species of the 
Anopheles which can carry the malarial parasite, and of those 
existing in Ceylon I think that it can be definitely stated that 
Myzomyia Rossii has nothing to do with the spread of malarial 
fever. 
I have also failed to find the parasite in Myzorhynchus bar » 
birostris , which is also to be considered as a non-carrier of 
malaria. 
Of the Anophelinse found in Ceylon which are recognized to 
be malaria-carriers, Myzomyia culicifacies is the best known. 
And this is the one found associated with epidemics in Ceylon, 
e.g. 9 at Mutwal, and with the bad malarial districts, e.g ., Meda* 
gama, in the Province of Uva.
