Head as long as broad ; snout rather pointed, shorter than 

 the orbit ; canthus rostralis distinct ; loreal region feebly oblique, 

 concave ; nostril equidistant from the eye and the tip of the snout ; 

 interorbital space as broad as or a little narrower than the upper 

 eyelid; tympanum distinct, -^ the size of the eye. 



Fingers rather swollen at the end, first as long as or a little 

 shorter than the second. 



Tibio-tarsal articulation reaching between the eye and the tip 

 of the snout. Toes ending in small but distinct discs, entirely 

 webbed ; subarticular tubercles moderate ; a tarsal fold ; inner 

 metatarsal tubercle narrow, i or rather more than ^ the length 

 of the inner toe ; no outer tubercle. 



Back wart}'; a rather strong fold above the tympanum ; pos- 

 terior part of upper eyelid with small warts ; a transverse fold 

 across the head, behind the upper eyelids. Lower parts smooth. 



Brown above, with ill-defined darker spots; a dark cross-bar, 

 light-edged in front, between the eyes; limbs with dark cross- 

 bands. Yellowish beneath, with or without brown marljling on 

 the throat. 



Tadpole with the tail less than twice the length of the body 

 and with obtuse point. , Beak narrowly edged with black ; labial 

 teeth in 2 upper and 2 lower series, the inner series interrupted. 



Habitat. Celebes. 



This species is founded on apparently young specimens, 32 

 milhm. from snout to vent. The shorter first finger appears to 

 distinguish the species from its allies. 



Roux {Rev. Suisse Zool. XXVI, 1918, p. 412) may be right in 

 regarding R. microtympanum as a synonym of R. modesta. How- 

 ever, I have examined a young R. modesta from Buol, Celebes, 

 measuring 30 mm., and which has the first finger a little longer 

 than the second.

Vomerine teeth in oblique oval groups behind the level of 

 the choanae. Lower jaw without bonj- prominences in front 



Head moderate, moderately depressed, a little broader than 

 long; snout rounded, scarcely projecting beyond the mouth, as 

 long as or a little longer than the eye ; canthus rostralis obtuse ; 

 loreal region moderately oblique, slightly concave ; nostril nearly 

 equidistant from the eye and the end of the snout ; the distance 

 between the nostrils equal to or a Httle greater than the inter- 

 orbital width, which is nearly equal to that of the upper eyelid ; 

 tympanum very distinct, ^ to f the diameter of the eye, 1^ to 2 

 times its distance from the latter.
