velopcd, a round outer and a very elongate inner metatarsal tubercle, both 

 verj'^ distinct. Tibiotarsal articulation reaching only to the tympanum. 

 Skin smooth on the snout, slightly granular on the eyelids and back, the 

 granules on the back tending to form a series of indistinct longitudinal rows; 

 sides of the body warty; ventral surface strongly granular. 



Coloration in alcohol nearlj' uniform j'ellowish grey; a dark canthal stripe 

 fading out behind the tympanum; a number of indistinct brownish bands 

 extending along the back; three oblique bands across the legs, these tending 

 to form continuous lines when the leg is half extended; ventral surface uni- 

 form yellowish grey, much yellower than the dorsal surface. In life the 

 ground-tone w^as yellowish pink and the dark pattern was fairlj^ distinct.
