The last parasite I have to mention is the Leucocytozoon, which 

 is rare, and at present undetermined. It occurs in the blood of 

 birds in the form of a long, spindle-shaped, unpigmented body, 

 roughly about three or four times the length of a normal erythrocyte, 

 and about one-third of the breadth. It is colourless, and always 

 free from pigment. Very little is known about this parasite, 

 and it is found in the blood only in its sexual forms. Schaudin 

 thought that its asexual m.ultiplication took place in the Mal- 

 pighian vessels of a mosquito, with the formation of spirochete
