From the introduction:
"The following is the index-catalogue of parasites and hosts records from India covering the year 1980. The results that stem from birds of the Zoological Gardens (Plimmer, 1912-1916; Scott, 1926, 1927; Knowles, 1928) are not incorporated as one may not be certain about the origin of the birds and the source of infection. Furthermore, in many cases the recorded host name does not appear to be the correct one, and in such cases it is placed in parentheses, the correct name being given without parentheses. For reference to hosts, Austin (1961), Ripley (1961) and Ali and Ripley (1968-1974) have been consulted, and for the parasites Wenyon (1926), Bhatia (1938), as well as original references were seen. The question of the parasites of migrant birds is glossed over here. If the parasite has been found in this area, it is listed here though in all probability the infection might have been acquired elsewhere.
Besides unnames species and microfillaria there are about 96 species and subspecies of avian haematozoa known to occur in India. Many of these species require revision in light of modern approaches to taxonomy. To facilitate such study, and to promote further research on the subject, an appendix (Appendix 1) is incorporated herein to cover references on other aspects of the parasite – those carried out in India, as well as some important checklists and revisionary papers of interest to research of this field of science."
