Several specimens were brought by Mr. Jerdon from Darjeeling. 
This is the frog mentioned by Mr. Jerdon (Proc. As. Soc. 1870, 
p- 83) and described by Dr. Anderson (Proc. Zool. Soc. 1871, p. 208) 
as Polypedates smaragdinus of Blyth; but there is no evidence what- 
ever that Blyth had this species before him; he merely says (Journ.As. 
Soc. Beng. xxi. p. 355):—“ A tree-frog from the Naga hills, Assam 
(P. smaragdinus, nobis). Length of the body 33 inches, hind limb 
53 inches. Wholly green above, changing in spirit to livid blue, 
underparts white.” This vague diagnosis may apply to very different 
species, and certainly better to some than to the present frog from 
Darjeeling. 
PoLYPEDATES FORMOSUS, sp. n. (Plate LXV. fig. B.) 
Habit similar to that of P. afyhana. 
Snout flat, short, rounded, with distinct canthus rostralis. Loreal 
region subvertical, with a very slight impression. Eye of moderate 
size ; tympanum very small, only as large as the disk of the third 
finger. Limbs slender; fingers exceedingly long: the second 
longer than the first, but shorter than the fourth, the third exceed- 
ing the others in length; fingers not webbed, with large disks, 
larger than those of the toes. ‘Toes fully webbed; metatarsal tuber- 
cle indistinct. Skin guite smooth. Choanz and Eustachian tubes 
narrow ; vomerine teeth in two very short groups between the 
choane. Tongue without free papilla. Upper parts green, mar-
