above, and, likewise, slightly declivous upon the snout, at the tip of 

 which the nostrils are situated, and between which a slight groove 

 may be traced to the occiput, along the middle line of the cranium. 

 The membranous proboscis is almost dried up, and reduced to a knob 

 upon the truncated part of the snout, in which state it resembles 

 Dendrobate-s, except in being narrower. The inner nostrils are large, 

 situated close to the maxillary, hence far apart from each other. The 

 openings of the Eustacbian tubes are very minute. The tongue ap- 

 pears to be quite elongated and entire posteriorly. The eyes are pro- 

 portionally large, subelliptical, their longitudinal diameter being equal 

 to the distance between the orbits and the end of the snout. The 

 interocular space, on the other hand, is equal to their diameter. The 

 tympanum is entirely hidden under the skin, and parotid glands are 

 not extant. The body is slender and elongated, not in the least bufo- 

 nine in its aspect, but rather recalling to mind the most slender forms 

 of the ranine group. The legs are slender also, the anterior ones are 

 shorter than the trunk. The fingers are united at their base by a 

 rudimentary membrane ; they are slender, their tip slightly swollen 

 beneath, each articulation being protected by a small, rounded tubercle. 

 The third finger is considerably the longest ; the first a little longer 

 than the second, which is almost equal to the fourth. The palm of 

 the hand exhibits small tubercles or granules, and upon its base is 

 seen a metacarpal, rounded knob. The posterior legs appear to hold 

 the same relation towards the body and head, as in R. dancini, that 

 is to say, if brought forward alongside of the body they would extend 

 beyond the snout, by the whole length of the foot. The toes are 

 slender and elongated, but slightly webbed at their base. Their 

 structure is the same as the fingers ; they are provided with small 

 tubercles under their articulations, and their tip is swollen beneath. 

 There are two quite conspicuous, metatarsal tubercles, the outer one 

 being the largest, subcircular, and conical. 



The skin is perfectly smooth all over. There are two ovoid, lumbar, 

 proportionally large patches, one on each side, simulating the lumbar 

 glands in Pleurorlenia, the surface of which is apparently smooth. 



The ground color above is reddish, minutely dotted with white, the 

 dots very much crowded on the sides of the abdomen, so as to give a 

 rather milky appearance to that region. Just behind the occiput on 

 the middle of the back may be seen an elongated and very regular 

 whitish spot, twice as long as wide and rounded upon its extremities.
