Tympanum one third the size of the eye in females, but larger in males. Limbs strong; disks well developed, those of the fingers rather larger than those of the toes. Fingers not webbed, the first rather longer than the second, and equal in length to the fourth, the third being the longest. Toes completely webbed; a single elongate metatarsal tubercle. Skin quite smooth, not adherent to the surface of the head ; no indication of a curved osseous crest. Choanae and Eustachian tubes of moderate width ; vomerine teeth in two oblique series between the choanae. Tongue without free papilla. Male with an external vocal sac behind each angle of the mouth. Upper surface of the head and back green (sometimes with some irregular black spots) ; sides of the head and body and the limbs dark brown, this colour being sharply defined towards the green of the back ; lower parts whitish, with the throat and chest brownish. A white line along the upper lip towards the axil. Loins and hind part of the thighs marbled with whitish. Legs with dark cross bars above. Male. Female. millim. millim. Length of bodv 51 93 hind limb 93 175 ,, tarsus 15 28 ,, fourth toe 27 50 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 oi Blyth ; but there is no evidence whatever that Blyth had this species before him; he merely says (Journ.As. Soc. Beng. xxi. p. 3 5 5 ) : - " A tree-frog from the Naga hills, Assam (P. smaragdinus, nobis). Length of the body 3\ inches, hind limb 5\ 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. afghana. 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 exceeding the others in length ; fingers not webbed, with large disks, larger than those of the toes. Toes fully webbed ; metatarsal tubercle indistinct. Skin quite smooth. Choanae and Eustachian tubes narrow ; vomerine teeth in two very short groups between the choanae. Tongue without free papilla.
