 Tongue narrow, oval, nicked l)ehind; vomerine teeth in two short 

 oblique series some distance l)ehind the choame, not extending later- 

 ally beyond the latter and strongly converging backward, the interval 

 between them about equaling their distance from the choanie; nostrils 

 much nearer the tip of the snout than the eyes, their distanc<^ from 

 the eye nearly equalling the diameter of the latter; upper eyelids 

 nearly as wide as interorbital space; tympanum small, about one-third 

 the diameter of the eye, its distance from the eye equaling the diame- 

 ter; fingers with well-developed disks, first eciualing sc^'.ond; disks of 

 toes smaller than those of the fingers; tip of first toe i-eaching the 

 base of the disk of the second; two moderate metatarsal tubercles;

Coloration of llvhuj sj)t'clvien.s. — The variation of color presented 

 by this species is simply endless, there being scarcely ever two speci- 

 mens alike, and a detailed description of individuals is therefore use- 

 less. The description of the first adult specimen collected may serve 

 as an example, however, to which 1 may then append the notes writ- 

 ten down with large series of living specimens before mo.
