erythrocyte of the bird and then grows in the long axis of the 

 cell, and turns round the end of the nucleus, aiid it contains 

 pigment. It has been shown by the Sergents and by Aragao 



that a species of fly — Lynchia viaura — is the principal host. 

 The process of fertilization in these parasites has been described 

 by MacOallum, and it is believed that other stages are found in 

 the lungs. 



I have found these parasites in 69 birds of 48 different species, 

 in 46 of the latter for the first time. 



The following list shows that the parasite is very widely 

 distributed. 76 of the hosts came from Africa and 42 from the 

 Americas.
