and young. Vomerine teeth in two oblique series converging behind 

 and commencing from between the inner nostrils. Inner nostrils 

 and Eustachian tubes rather narrow. Skin of adult examples smooth, 

 except the lower leg and the foot, which are more or less covered 

 with tuberosities ; in some young examples also the sides are tuber- 

 cular. Hind limbs thick and short, the distance between the vent 

 and heel being but little less than the length of the body. Tips of 

 the fingers and toes swollen, those of the latter more so than those 

 of the former; toes completely webbed, a cutaneous fringe along 

 the outside of the first and fifth toes ; a narrow fringe along the inner 

 metatarsal edge, including a single elongate tubercle. An oblique 

 black band descends from behind the eye towards the shoulder. 

 Upper parts blackish or blackish brown, sometimes marbled with 

 darker on the sides and legs ; adult females with a yellow vertebral 

 band from the snout to the vent. Lower parts whitish, throat finely 

 marbled with brown. There is no light band between the eyes. 



Of this species we have specimens of the different sexes and ages 

 from Matang. An adult male is 3 inches long, the length of the 

 hind leg being 4| inches. 



Like Rana kuhhi and the Javan R. macrodon, to which this 

 species is allied, it lacks a gular sac or sublingual openings. 



Leptobrachium gracile. 



Similar to Leptobrachium hasseltii, but with much more slender 

 limbs. 



Snout not depressed, as long as the eye, with distinct canthus 

 rostralis, and with the loreal region but slightly shelving. Eye 

 large, prominent ; tympanum distinct, with a curved linear fold 

 above ; inner nostrils much narrower than the Eustachian tubes ; 

 tongue very large, filling the entire cavity of the mouth, notched 

 behind. Skin perfectly smooth. Third finger considerably longer 

 than the others. The length of the body is but little more than the 

 distance between the vent and heel. Metatarsus without tubercle ; 

 toes connected by a very short basal membrane. Upper parts grey- 

 ish olive ; a whitish spot below the eye, upper arm and elbow 

 whitish ; hind limb with blackish cross bars, lower and lateral parts 

 of the body and hind limb with rather large irregular black spots.

BUFO LEPTOPUS. 



Allied to Bufo cruentatus {— Hylaplesia borlonica, Boie) and 

 Hylaplesia breoipes (Ptrs.), from which latter species it is distin- 

 guished principally by the presence of two metatarsal tubercles.
