INTRODUCTION. 15 



Spobozoa from Indian Millipedes, and Ray (1933), Ray and 

 Chakravarti (1933), and Chakravarti (1933, 1935, 1936) have 

 described Stenophora khagendree, Stenophora ellipsoidi, Mono- 

 ductus lunatus, Hyalosporina cambolopsisse, and Hyalosporina 

 rayi. Three of these forms are placed in new families by their 

 authors. 



CocciDiA. — Simond in 1901 was the first to pubKsh a series 

 of papers on Hsemogregarines from Indian tortoises and the 

 gavial, and Laveran and Mesnil (1902) and Laveran and 

 Nattan-Larrier (1912) observed Hsemogregarines in certain 

 other tortoises. The pioneer work on the HiEMATOZOA in 

 Ceylon Avas carried out by Castellani and Willey (1904, 1905), 

 Robertson (1908, 1910), and Dobell (1910). James (1905), 

 Bentley (1905), Christophers (1905, 1906), and Patton (1908, 

 1909) described species of Hsemogregarina and Hepatozoon 

 from various mammals, and the sexual cycle of Hepatozoon 

 canis was fully worked out by Christophers (1907, 1912). 



Froilano de Mello and his colleagues, working in Portuguese 

 India, have pubhshed a number of papers (1915-1937) dealing 

 with the Haimogregarines of hzards and Toxoplasmids of 

 various birds. De Mello also described (1921) Adelea pache- 

 lebrse in a mollusc. 



In the family Eimeriidse many species are now known 

 from hosts belonging to all classes of Vertebrates. Cooper 

 and Gulati (1926), Cooper (1926, 1927), Sen (1932), and Ware 

 (1936) recorded cases of bovine Coccidiosis. Eaiowles and 

 Das-Gupta (1931, 1934) studied the Coccidia of the mon- 

 goose, cat, and lizard, and Das-Gupta (1934) recorded a case 

 of coccidial infection in man. Ray (1935 a, h) described 

 Wenyonella hoarei from the squirrel and Eimeria laminata 

 from the common toad ; and Ray and M. Das-Gupta (1935) 

 described Isospora wenyoni from the toad, and also (1937 a, b) 

 described Coccidia from a Hzard and the cobra. Setna and 

 Bana (1935 a, b), working in Bombay, described Eimeria 

 harpodoni from a fish and Eimeria fiaviviridis from a lizard. 

 They have also recorded the occurrence of Coccidia in a 

 number of species of marine fish. 



H^MOSPORiDiA. — Ab mentioned already, Vandyke Carter 

 (1888), Evans (1888), Hehir (1893), and Crombie (1894) were 

 the earhest to observe the malarial parasites in India. But it 

 was the memorable work of Ronald Ross (1895, 1897, 1898) 

 that laid the foundation of the correct understanding of the 

 life-cycle of the malarial parasites in man and birds. He 

 succeeded in estabhshing the fact that further development 

 of the human malarial parasites takes place in the body of the 

 dapple-winged mosquitoes that have fed on the blood of malarial 

 patients ; and he elucidated the complete life -cycle of the malarial
