2. Herpetomonas culicis from Culex pipiens and H. jaculum 
from Nepa cinerea have infected birds when fed to them. The 
cycle of the flagellates in the avian hosts resembled morpho- 
logically that in the insects. 
3. The disease induced may run an acute or a chronic course. 
In the acute cases in our birds, the flagellate form of the parasite 
was the more obvious at death. In the chronic cases, the non- 
flagellate forms were the more numerous. 
4. Natural herpetomoniasis of a pigeon has been recorded by 
Drs Edm. and Et. Sergent in Algeria. This affords a parallel case 
with the natural and induced herpetomoniasis in mice previously 
recorded by us. 
5. Members of all classes of vertebrates may be capable of 
acting as reservoirs of herpetomoniasis, and the virus may exist in 
a very attenuated condition and so be difficult of detection.
