 colours may be subject to a slight uniform discoloration.

During observations made during 1916-1917 with the German 

 section in the Dardanelles, PJilebofomus papatasii was found to be 

 the carrier of the disease. It chiefly occurs between mid-May and 

 mid- October and the fever was prevalent during those months. 

 P. papatasii appears to be most active at sunrise and during the 

 hottest hours of the day. It is extremely sensitive to air currents 

 and such disturbances as are caused by waving the hand are sufficient 

 to affect it at a distance of about 5 feet.

The sheep trypanosome has hitherto been found by only two 

 observers. Woodcock in 1910 saw a living trypanosome in sheep 

 blood and Behn found it in 1911 and 1912 in thick cover glass prepara- 

 tions from some sheep in Thuringia. Cultivation from sheep blood 

 has not yet been successful. 



It is known that in Germany nearly all examples of the Hippoboscid 

 fly, Melophac/us ovinus, L., are infected with a trypaniform flageUate 

 named Crithidia melophagi by Flu in 1908. These flagellates are so 

 remarkably like the developmental stages of the trypanosomes from 

 Glossina that some observers held them to be only developmental 

 forms of the sheep trypanosome, which latter may be as rare in the 

 blood of sheep as Trypanosoma theileri in that of cattle. 



Experiments made by the author show that the sheep trypanosome 

 is a distinct species, transmitted by M. ovinus, that must be called 

 Trypanosoma melophagi, Crithidia melophagi being a developmental 

 form of it. Further experiments are being made with a view to 

 confirming the above result and to elucidate the entire developmental 

 cycle,

The experiments here described are considered to afford decisive 

 evidence that the causal agents of equine piroplasmosis, Nuttallia 

 equi and Piroplasma caballi, are distinct.
