VI AUTHORS PREFACE. 



from India. The 320 species described, in this volume are- 

 but a small fraction of the total kno^^^n from other parts of 

 the world. All the species that are as yet known from India, 

 Bm-ma, and Ceylon have been brought together, but a large 

 number still await discovery. The geographical distribution 

 of the parasites usually follows that of their hosts. Lists 

 of Parasites and their Hosts, and of Hosts and their Parasites 

 have been given in the Introduction and the Appendix, 

 and it is hoped that these ^vill be of use to those looking- 

 for the parasites in particular hosts. It may be pointed out, 

 however, that the discovery of a parasite in a host not recorded 

 in the list does not mean that the organism is new to science. 

 It may aheady have been recorded from the same host or in 

 some other host in other parts of the world. Keeping this 

 in view, the discoverer should not rely too much on this volume, 

 but should carefully explore the monographs and original 

 papers to which the Bibliography, given at the end of the volume , 

 will furnish a guide. The literature on the subject of Sporozoa 

 is very vast, and it has been possible to give a selection onty. 

 For the convenience of the reader the Bibliography has been 

 divided into a number of sections corresponding to the sub- 

 classes or orders, and if a reference is not found under " Text- 

 books and Sporozoa in General " it should be looked for in 

 the section of the Bibliography relating to the particular 

 order. 



The species of each genus have been arranged in alphabetical 

 order, except in a few cases where the species occurrmg in 

 man or some other group of hosts have been brought together. 

 In the synonymies, given under each species, references to 

 all the records from India, Burma, and Ceylon have been 

 included, and a j mark prefixed to all such references. A selec- 

 tion of other references which are considered important or 

 useful is also given. 



In the Introduction I have given a short account of the 

 general organization and structure, and discussed the phylo- 

 geny and classification of the group. It seems obvious that 

 Sporozoa should preferably be divided into two classes, 

 viz., Sporozoa s. str. and Amoebosporidia, but the two classes-
