Vomerine teeth in short oblique series between the choanse or 

 extending a Httle beyond the level of their posterior 1:)orders, 

 equally distant from each other and from the latter. 



Head longer than broad , much depressed ; snout a little longer 

 than the Qy^, niore or less obtuseh^ pointed, moderately or feebly 

 projecting be^^ond the mouth ; canthus rostralis strong ; loreal 

 region feebly oblique, concave ; nostril nearer the end of the snout 

 than the eye ; distance between the nostrils equal to or a little 

 less than the interorbital region, which equals or exceeds that of 

 the upper e^^elid ; tympanum ver}^ distinct . i to nearh' once the 

 diameter of the eye, 2 to 5 times as long as its distance from the 

 latter. 



Fore limb slender ; lingers long and slender, with small discs 

 which are longer than broad and bear a groove separating the 

 upper from the lower surface ; first finger a little longer than the 

 second, third longer than the snout ; subarticular tubercles large, 

 very prominent. 



Hind limb long and slender ; tibio-tarsal articulation reaching 

 the tip of the snout or beyond ; heels strongly overlapping when 

 the limbs are folded at right angles to the bod}^ ; tibia 5 to 6 

 times as long as broad, i| to I'f times in length from snout to vent, 

 as long as or a little shorter than the fore limb, considerably longer 

 than the foot. Toes slender, with discs same as those of the 

 fingers but a little broader, webbed to the discs of the third and 

 fifth, two phalanges (rarely one only) of fourth free ; outer meta- 

 tarsals separated nearly to the base ; subarticular tubercles large 

 and prominent ; no tarsal fold ; inner metatarsal tubercle oval, 

 about \ the length of the inner toe ; a more or less distinct outer 

 tubercle. 



Skin smooth ; a feebly prominent, narrow glandular dorso- 

 lateral fold from above the tympanum to the hip, its distance 

 from its fellow, on the back, 6 to 6| times in length from snout 

 to vent ; another, sometimes indistinct, from behind the tympanum 

 to the shoulder. 



I/ight brown above, scarcely or not spotted, sides dark brown ' ; 

 a light vertebral streak may be present above the cocc^^'x ; dorso- 

 lateral fold whitish, black-edged on the outer side ; upper lip 

 whitish with a dark margin ; limbs with or without narrow dark 

 cross-bands. Lower parts white, the throat brown or with crowded 

 brown spots, usually witli a light median line. 



Males with internal vocal sacs ; no other secondar}^ sexual 

 characters. 



' The light bar ascending from the upper lip between the eye and the tympa- 

 num, regarded by .Annandale as a specific character of R. lepfoglossa, is pre- 

 sent m one of the specimens from Klong Bang Lai.
