 He did not find any evidence of a blepharoplast. 



Habitat. — Blood of ox, Bos indicus Linn. (?) : Punjab,

Smaller than B. bigemiTia. Amoeboid forms chiefly rounded, 

 often ovoid, pear-shaped, or rod-shaped forms also occur. 



Fig. 148. — Babesia bovis (Babes). (After Nuttall.) 



In films stained with Romanowsky's stain the nucleus is 

 seen as a red dot, with a string of fine granules extending from 

 it. Two pear-shaped individuals often lie with their pointed 

 ends together and forming an obtuse angle, or even in a line. 

 The forms are smaller than the radius of the corpuscle, usually 

 He near the margin of the corpuscle, and trypan blue is usually 

 effective. 



Dimensions. — Round forms 1-1-5 jn in diameter ; pyriform 

 individuals 1*5-2 ju, in length. 



Remarks. — The organisms were marginal in position and the 

 pointed ends of a pair of individuals included an obtuse 

 angle, or the individuals were in a straight line. The host 

 had shown acute piroplasmosis associated with hsemoglobi- 

 nuria, and trypan blue had been administered, but without 

 producing any effect. 



Habitat. — Blood of an Indian buffalo, Bos bubalus Linn. : 

 Madras, Belgaum.
