The subject of the mosquitoes of Ceylon in their relation to 

 malaria is covered in a publication by Mr. Green, issued by the 

 Royal Botanic Gardens, Ceylon, Series i, No. 25, December, 

 1901. One item only may be noted from this communication, 

 namely, that Mr. Green estimates at least 2^,000 deaths to have 

 been due to malaria in the year 1899. From this some idea may 

 be formed of the number of cases of malaria, comparatively few 

 of the cases resulting fatally. In one instance out of 600 coolies 

 employed in railway construction half of them contracted 

 malarial fever within a month and were compelled to give up 

 work. The Anopheles that seems to be responsible for malaria 

 in Ceylon is A. rossii, the species which was the subject of the 

 early studies in India leading to the discovery of the true cycle of 

 the malarial parasite. 



The mosquitoes collected in Egypt and France in February and 

 March on the homeward trip all proved to be Czdex pipiens 

 Linne. They were not specially abundant in Luxor, Cairo or 

 Port Said where they were collected, nor in Mentone, France, 

 where additional specimens were secured. 



Reviewing the above, it will be noted, as indicated at the out 

 set, that Culex pipiens Linne is the common house species in 

 nearly every part of the world visited. It was* collected from 

 below the equator, northward to a latitude of Newfoundland ,
