&c.," with its Supplement of 1892 ; a,nd I have quoted the name given 

 to each of my species in each of those works ; though in some cases 

 I have found it difficult to identify them. As a rule, no further attempt 

 has been made to give the synonymy of the species : that will be 

 found sufficiently given in the books I refer to ; and as this paper is 

 merely a supplement to these, and not a complete treatise, I see no 

 necessity for repeating what is already in print. Mr. Clarke said in 

 his ^' Review:" " No person is likely to undertake the study of Indian 

 ferns without this book " [the Synopsis Filicum] " at his elbow ; and 

 I have not wished to print more repetition than the large quantity 

 always absolutely necessary in work of this kind." So I would 

 say of Mr. Clarke's " Review" — though the price of the " Transactions 

 of the Linnean Society," in which it appeared, is somewhat prohibitory. 

 Beddome's " Handbook " also must be kept at hand and the Supplement 

 of 1892. A third edition of the Si/nopsis Filicum is much wanted, 

 though Mr. Baker, in 1891 and since, has contributed summaries of 

 new ferns discovered or described since 1874 to the "Annals of 

 Botany."' 



The system of classification and nomenclature followed in this paper 

 is that of Hooker and Baker's Synojysis Filicum. Specific names used 

 in the Synojysisj in Clarke's " Review," and in Beddome's *' Handbook," 

 with its Supplement, are adhered to so far as is possible. And in 

 reviving some species which, though originally proposed and named 

 by competent authorities, have been dro])ped by recent authors, and 

 in raising so-called varieties to the rank of species, I have 

 adopted the names originally given by the collectors or describers 

 of them. 



The present list admits 212 species : of these 16 are new, including 

 3 which have before been described by other authors as varieties of old 

 species; 45 are new to the regions dealt with, and 6 old species are 

 new to the Indian region. 20 are old species revived, or so-called 

 varieties erected into species. In his " Review " Mr. Clarke 

 admitted 363 species of ferns, besides many varieties, in Northern 

 India, of which 16 were new. 142 species were, he said, found in 

 the Himalaya west of Nepal, including Afghanistan apparently. 



No place is given in this list to so-called varieties, though in a few 

 instances " forms " are noted where there seems to be a divergence
