3. BATRACHIANS. 
Rana Boulengeri. 
This species belongs to that division of the genus of which 
Rana Kuhlii and Rana Liebigii are characteristic forms. 
Vomerine teeth in two short oblique series, each starting 
from the inner edge of the choana, Head large, broad, much 
depressed ; snout very short and rounded; canthus rostralis 
short but distinct ; upper eyelid a little broader than the inter- 
orbital space; tympanum hidden. First finger longer than 
the second; toes with swollen extremity, entirely webbed ; 
subarticular tubercles well developed; inner metatarsal 
tubercle elongate ; no outer tubercle. The tibio-tarsal joint 
does not reach the end of the snout when the limb is carried 
forward. Skin of the upper parts covered with large elon- 
gate warts and small rounded tubercles ; a strong fold of the 
skin above the tympanum ; no glandular fold on the side of 
the back. Uniform blackish brown above. Male with two 
internal vocal sacs. 
As in Rana Liebigit, the breeding male has extremely 
thick forearms, but without any special armature. The rudi- 
mentary thumb and a large rounded tubercle on the upper 
side of the first finger are thickly studded with horny spines, 
the second and third fingers having similar spines, but less 
numerous. ‘The whole of the chest is covered with smaller 
and larger rounded tubercles, each armed with a black conical 
horny spine, and similar but smaller dermal structures are 
scattered over the abdomen and also over the throat. 
Two specimens of this large species were sent by Mr. Pratt 
from Ichang. The length from the snout to the vent is 4 
inches. 
Hynobius chinensis. 
Allied to the Japanese Hynobius nebulosus, but with the 
series of vomerine teeth much shorter, extending backwards 
only to the middle of the eyeball. General habit short 
and stout; head large, nearly as broad as long, its length 
being rather more than one fourth of the length of the trunk. 
Tail compressed in its whole length, but without crest; body 
with eleven lateral folds. The limbs mect when adpressed ; 
fifth toe well developed; no carpal or tarsal tubercles. Skin
