318 SPOKOZOA. 



Remarks. — The piroplasms of sheep and goats continue to 

 be referred to Piroplasma ovis Laveran & Nicolle (1909), but 

 Wenyon (1926) has restricted that name to the organisms of 

 intermediate size, and named the larger form as B. motasi 

 and the smaller form as B. sergenti. Thus B. motasi, B. ovis,

 (From Wenyon, after Lestoquard.) 



and B. sergenti of sheep and goats correspond to B. bigemina, 

 B. bovis, and B. mutans of cattle. B. sergenti produces no 

 recognizable symptoms. 



Habitat. — Blood of goat, Capra hircus Linn. : United 

 Provinces, Muktesar. 



263. Babesia soricis (Christophers). 



^Piroplasma soricis, Nuttall, 1908. 

 Babesia soricis, Hoare, 1930, p. 246. 



Parasites of moderate size, occupying one-third of the cor- 

 puscle in the larger forms. Did not show typical binary forms. 



Remarks. — ^NuttaU (1908) stated that " Christophers has 

 found a parasite in musk rats in India which he names 

 P[iroplasmM] soricis." Hoare (1930), faihng to trace the 

 original pubhcation, referred to Christophers, who gave 

 him the meagre information quoted above and remarked 

 that he had found the parasite, but never described it or referred 

 to it in print. 



Habitat. — Red blood-corpuscles of the musk rat, Crocidura 

 cserulea (Kerr) : Madras, Guindy. 



264. Babesia tropicus (Lingard & Jennings). (Fig. 158.) 



"fPiroplasma tropicus (part), Lingard & Jennings, 1904, pp. 161-5 ; 

 Baldrey, 1910, pp. 572-7, pi. xxxix. 



Small ring-forms, with central position of the chromatin in 

 many of the infected red corpuscles. Chromatin in the form 

 of two dots and a connecting bar between them. Pear-shaped 

 forms rare in corpuscles, but occasionally seen free in the 

 plasma. 



Remarks. — Lingard and Jennings (1904) found piroplasms 

 in bovines, buffaloes, equines, elephants, camels, goats, sheep,
