orbit ; canthus rostralis very obtuse ; loreal region very oblique, 

 slightly concave ; nostril nearer the eye than the end of the snout ; 

 interorbital space a little nari-ower than the upper eyelid ; tym- 

 panum hidden. Fingers rather short, feebly swollen at the tips, 

 first extending considerably beyond second ; subarticular tubercles 

 moderately developed. Toes rather short, broadly webbed to the 

 tips, which are dilated into small but very distinct disks ; sub- 

 articular tubercles moderate, oval ; inner metatarsal tubercle feebly 

 prominent, elongate, measuring two thirds its distance from the 

 tip of the inner toe ; no outer metatarsal tubercle ; a feeble 

 dermal fold along the inner edge of the tarsus. The tibio-tarsal 

 articulation reaches the eye ; tibia about half length of head and 

 body. Skin of upper parts granular or shagreened, with numerous 

 warts, which may be small and subcorneal or large and elongate on 

 the back ; these warts may bear black horny spinules ; a strong 

 fold across the head, connecting the posterior borders of 

 the upper eyelids ; a very strong ridge from the eye to the 

 shoulder; no glandular dorso-lateral fold; lower parts smooth. 

 Dark olive or blackish brown above ; lips with darker vertical 

 bars ; limbs with more or less distinct black cross-bars ; hinder 

 side of thighs black, with more or less distinct Hghter marblings ; 

 lower parts whitish, throat and lower surface of limbs spotted or 

 marbled with blackish. Male with small internal vocal sacs ; 

 during the breeding-season the fore limbs are more or less strongly 

 thickened, and the breast and inner side of the three inner fingers 

 armed with small black horny spines.

This species is exactly intermediate between M. Tcuhlii and 

 R. liebigii.

Vomerine teeth in two oblique oval groups in the middle 

 between the choanse. Head as long as broad ; snout as long as the 

 diameter of the orbit, obtusely pointed, projecting beyond the 

 mouth, with distinct canthus and feebly oblique, slightly concave 

 lores ; nostril nearer the end of the snout than the eye ; inter- 

 orbital space as broad as the upper eyelid ; tympanum very distinct, 

 three fifths or two thirds the diameter of the eye. Fingers 

 slender, feebly swollen at the end, first extending beyond second ; 

 subarticular tubercles very strong. Toes slender, two-thirds 

 webbed, with swollen tips and strong subarticular tubercles ; inner 

 metatarsal tubercle small, oval ; a very prominent, round, outer 

 metatarsal tubercle. Tibio-tarsal articulation reaches the anterior 

 border of the eye ; tibia half as long as head and body. Upper 

 parts finely granular ; a very prominent, very broad dorso-lateral 

 glandular fold, almost deserving to be termed a parotoid, its width 

 above the shoulder at least as gi-eat as that of the upper eyelid ;
