Ichanp^ by Mr. Pratt, one of the largest being 31 inches long, 

 the tail measuring 5 inches. 



3. Batrachians. 

 Rana Boulengeri. 



This species belongs to that division of the genus of which 

 Rana Kuhlii and Rana Liehigii 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 tlie snout when the limb is can-ied 

 forward. Skin of tlie 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. 



Ab in Rana Liehigii, the breeding male has extremely 

 thick forearms, but witliout 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 cliest 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. 



Hynohius chinensis. 



Allied to the Japanese Hynobius nehulosus, 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 meet when adpressed ; 

 fifth toe well developed ; no carpal or tarsal tubercles. Skin
