corpuscle, and contained chromatin granules of varying size 

 and shape. Internal organs of host contain the schizonts. 



Remarks. — Sarwar (1935) described a form from a goat in 

 the Punjab in which the parasites were mostly ovoid or round, 

 pear-shaped forms being rare. Single parasites found in 

 a corpuscle measured 2^ by 1-5/^. Although single parasites 

 were frequently seen, it was not uncommon to find two, 

 four, eight or sixteen individuals in one red cell. He also

found extracellular forms showing multiple division, but did 

 not regard them as Koch's " blue bodies," nor did he find 

 them in the internal organs of the host. He named the form 

 Piroplasma taylori. I (1936) thought that the form described 

 by Sarwar was identical with T. hirci Dsch. & Urod., 1924*.

 Provinces, Muktesar ; Punjab, Malwale (Sheikhupura). 



4. Family BABESIID^ Poche, 1913. 



Non-pigmented parasites of the red blood- corpuscles of 

 Mammals, which multiply in the corpuscle by division into 

 two or four. They are of varying size and shape, and usually 

 arrange themselves in pairs of pear-shaped individuals. The 

 forms in the corpuscles are individuals reproducing asexuaUy, 

 but probably some are gametocy-fces. 



Remarks. — Franca (1917, 1918) gave a detailed classification 

 of the family and recognized a number of genera. His classi- 

 fication was modified by du Toit (1918), who recognized six 

 genera, viz., Babesia Starcovici, Nicollia Nuttall, Nuttallia 

 Franca, Smithia Franca, Rossiella Nuttall, and Gonderia 

 du Toit. Wenyon (1926), Reichenow (1929), and many other 



* Through his courtesy I have now examined his preparations, and 

 the extra-corpuscular bodies (fig. 146, F, G) in the peripheral blood 

 which linterpreted as Koch's "blue bodies " cannot be regarded as such. 

 So his form, ought to be transferred to Babesia and linown as B. taylori 

 (Sarwar).
