Mr. J. Wood-Mason on the Genus Deidamia. Tat 
in the Museum is a very poor one; and the Ranide from all 
parts of India must be assiduously collected before sound 
results can be obtained. Let us hope that an urgent appeal 
for frogs from all parts of India [and Ceylon, W. F.] will be 
liberally responded to by local naturalists and collectors, with- 
out which aid the subject must long remain in its present un- 
satisfactory state. Mach contributor should not send merely 
the most conspicuous frogs from his neighbourhood, but all 
the species and varieties he can procure.”’ 
As an illustration of the liability to add to and perpetuate 
the confusion connected with some of the frogs and other 
reptiles, | may refer to a rare Ceylon frog found first on 
Adam’s Peak several years ago by Dr. Schmarda, Professor 
of Zoology in the University of Prague. On a fly-sheet after 
page 21 of the second part of Dr. Kelaart’s ‘ Prodromus of the 
Faunze of Ceylon,’ published in 1853, this frog is very briefly 
described by the late Dr. Kelaart under the following name, 
“ Polypedates (?) Schmarda,n.s. nobis” —the “Schmarda” being 
no doubt a slp of the pen for ‘‘Schmardana,” under which 
latter name, and under the genus Zzalus, Giinther refers to this 
then doubtful frog in his ‘ Indian Reptiles,’ p. 433. Theobald, 
in his Catalogue referred to, p. 85, gives this frog as follows:— 
“ Polypedates smaragdinus, Kelaart; Ceylon. Eyebrows armed 
with spines. Limbs studded with tubercular sharp-pointed 
spmes. A very peculiar species, and probably a distinct 
generic form.” Jerdon, in the paper referred to, pp. 88, 84, 
and Anderson, in his list of accessions to the collection of 
reptiles in the Indian Museum since 1865, refer distinctly to 
an Indian frog described by Blyth in footnote to p. 48 of 
Appendix to Kelaart’s ‘ Prod. Faun. Zeyl.’ as the Polypedates 
smaragdinus, found on the Khasi hills. The specitic name 
here means emerald-green ; and Mr. 'Theobald’s P. smaragdinus 
ought to have been P. Schmardana. On page 85 of the 
‘Annals and Magazine of Natural History’ for January 1872, 
containing ‘ Descriptions of some Ceylonese Reptiles and 
Batrachians”’ by Dr. Giinther, this frog is finally, and I suppose 
properly, named, though not yet described, as [xalus Schmar- 
danus (Kelaart).
