INTRODUCTION. 17 



Piroplasmids from hounds, Cooper (1926) from cattle, 

 Krishna Iyer (1933) from goats, and Achar and Shrikantiah 

 from sheep. Sarwar (1935) described Piroplasma taylori 

 from a goat, but I (1936) have shown that this form 

 appears to be identical with Theileria hirci. Shortt (1936) 

 has re-studied the Hfe-history of Babesia canis in the dog- 

 tick. 



Cnidosporidia. — Very Httle work has been done on the 

 Cnidosporidia. The Myxosporidia have been studied by 

 Bosanquet (1910), Southwell (1915), Southwell and Prashad 

 (1918), and Ray (1933). As regards the Microsporidia, 

 Korke (1916) described a species of Nosema parasitic in the 

 dog-flea. Mrs. H. A. Adie (1922) observed certain bodies in 

 Cimex rotundatus in a Kala-azar infected area in Assam, and 

 beheved them to be Leishman-Donovan bodies, but Christo- 

 phers (1922) and Short and Swaminath (1922) regarded the 

 organism as a species of Nosema, and described it as N. adiei. 

 Iyengar (1929) and Kudo (1929) have studied the micro- 

 sporidian parasites of Anopheline larvae. 



Sarcospobidia. — Shipley (1904) and Willey, Chalmers, and 

 Phillip (1904) described sarcosporidian infection in buffaloes 

 in Ceylon ; Chatter jee (1907) described what was probably 

 the same species from the heart-muscle of a cow in Calcutta. 

 Vasudevan (1927) described a case of sarcosporidian infection 

 of man in Madras. Hassan (1935) has described a new species 

 of Globidium from a cow. 



Haplosporidia. — Minchin and Fantham (1905) described 

 an organism, which they named Rhinosporidium kinealyi, 

 from a nasal polyp, and regarded it as belonging to the Haplo- 

 SPORiDiA, but Ash worth (1923) has shown that the organism 

 is a fungus. Vasudevan (1932) described a case of rhino- 

 sporial infection of the fore-arm of a man in Ceylon ; but 

 no true Haplosporidia have so far been described from 

 India. 



Distribution. 



The geographical distribution of parasites usually follows 

 that of their hosts. The names of the hosts, and the localities 

 in which any parasite has been found, are noted after the 

 description of the species, and, generally speaking, the same 

 parasite may be expected to occur in the same species of hosts 

 in other locahties also. The following Usts of (i) parasites 

 and their hosts, and (ii) the hosts and their parasites, will, 

 it is hoped, be found useful, and indicate at a glance which 

 of our commoner animals still remain to be examined for their 

 parasites.
