Vomerine teeth in oblique groups or short series between the 

 choanae, or extending a little beyond the level of their posterior 

 borders, equally distant from each other or a little nearer the 

 latter. 



Head longer than broad, much depressed ; snout more or less 

 pointed, more or less projecting beyond the mouth, longer than 

 the eye; canthus rostralis strong; loreal region nearly vertical, 

 deepl}' concave ; nostril nearer the tip of the snout than the eye ; 

 distance between the nostrils equal to the interorbital width, which 

 equals or a little exceeds that of the upper eyelid ; tympanum 

 very distinct, a to i the diameter of the eye, 3 to 5 times its dis- 

 tance from the latter. 



Fingers long and slender, with a feeble dermal border, termin- 

 ating in rather small discs which are as long as broad, 3 to f the 

 diameter of tympanum, with the upper surface separated from the 

 lower by a horseshoe-shaped groove ; first finger longer than the 

 second, third longer than the snout ; subarticular tubercles moder- 

 ately large, very prominent. 



Hind limb rather long and slender, the tibio-tarsal articulation 

 reaching the nostril or the tip of the snout, the heels strongly over- 

 lapping when the limbs are folded at right angles to the body ; 

 tibia 5 to 5^ times as long as broad, if to 2 times in length from 

 snout to vent, a little shorter than the fore limb, as long as or a 

 little longer than the foot. Toes ending in rather small discs, 

 same as those of the fingers, i to i webbed, 2 or 3 phalanges 

 of fourth free; the web rarely reaching the discs of the third and 

 fifth toes ; outer metatarsals separated nearly to the base ; sub- 

 articular tubercles rather small, prominent; no tarsal fold; inner 

 metatarsal tubercle oval, i to ^ the length of the inner toe ; a 

 round outer tubercle. 



Skin smooth or finely granulate above, with or without small 

 warts; a strong, narrow or moderately broad glaiidular dorso-
