ation are almost quite identical in equally large specimens of the two species,but 

 the hea.d is a little higher, the groups of vomerine teeth larger, the lips and 

 sides of the body and of the limbs more distinctly spotted or variegated with 

 black in Sikhimensis, than in Liehigii, and the skin is in the former quite 

 smooth with only a few scattered enlarged tubercles, while in B. Lieligii it is 

 rough, and has besides numerous enlarged tubercles. All these characters are, 

 however, not easily observed, and they are less marked in some specimens 

 than in others, while the fuller webbing of the present species, as compared 

 with JR. Liehigiij is constant.

Eept. Brit. Ind. p. 414, and Anderson, P. Z. S., 1871, p. 200. 

 I picked up some not fully developed and very young specimens in 

 September, between grass at the edge of a tank below Darjeeling. All 

 have the tips of fingers and toes markedly enlarged as in ordinary tree-frogs, 

 and the toes also distinctly webbed at the base ; none of them shew a trace of 

 vomerine teeth, which become developed in the more adult. 



9. Htlaeana maceodacttla, Giinther. 



This Chinese species* extends into Barma. I have received numerous 

 specimens through Mr. Kurz from Pegu, but they are all of small size, the 

 body measuring about one inch in length. The total length of the hind 

 limb varies ; sometimes it is double that of the body, but generally some 

 what less. In several specimens the fom-th toe is only half the length of 

 the body, which seems to be a peculiarity of the yomig frog. All other 

 characters perfectly agree with Giinther's description and figure. 



10. Hylaeais-a eetthe^a, (Schlegel). 



This species also extends from the Philippine islands through Siam into 

 Lower Bengal. I lately obtained two specimens near Calcutta (April 1871). 



Body above bright olive green, (turning to brownish green in spirit), 

 glandular folds silvery white, the upper one at each side margined with black. 

 The lower fold is indistinct in the young, but in the adult it continues to 

 the hind limb, and the sides of the vent below it are tubercular. Limbs 

 above brownish green, very minutely mottled with dark, and on the outer edges 

 tinged with silvery ; the outer sides of the tibise are besides longitudinally 

 striped. Hinder side of the femora green mth black spots, about the middle 

 densely tuberculated, while the rest of the skin above and below is smooth. 

 The larger of two specimens measures : body 1-75 inches, being equal to the 

 distance from the anus to half the tarsus ; fourth toe scarcely longer than 

 half the body. Two oblique groups of vomerine teeth. Two metatarsal 

 tubercles, the one at the base of the 1st toe small, compressed, the other at 

 * Giinther's types were from Hongkong.
