Ac.” with its Supplement of 1892 ; and I have quoted the name given 
to each of my species in each of those works ; though in somo 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 ] <4 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 Synopsis 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 Synopsis Filicum . Specific names used 
in the Synopsis , 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 dropped 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
