rulDer, Cope, I. c. 



Tongue siibcirciilar, slightly nicked and free behind. Vomerine 

 teeth in two small groups between the choanse. Head rather 

 depressed, as long as broad ; snout rounded, once and a half or once 

 and two thirds as long as the diameter of the eye; canthus rostralis 

 very indistinct ; loreal region not concave ; interorbital space gene- 

 rally broader than the upper eyelid ; tympanum very distinct, about 

 half the diameter of the eye. Fingers free ; no projecting rudiment 

 of pollex : toes three-fourths webbed ; disks smaller than the tym- 

 panum ; subarticular tubercles moderate. The hind limb being- 

 carried forwards along the body, the tibio-tarsal articulation marks 

 the eye, or between the latter and the tip of the snout. Upper 

 surfaces smooth, or covered with small tubercles ; lower surfaces 

 granulate ; a strong fold across the chest. Coloration very variable. 

 Brownish above, immaculate, or dotted, variegated, or longitudinally 

 striped with darker ; frequently a light streak along each side of the 

 back, beginning from the eye, or two curved dark markings on the 

 front of the back, forming an X the branches of which are separated ; 

 the sides of the thighs may be immaculate, or black- and white- 

 marbled. The uniform thighs correspond generally with the streaks 

 on the back (Bi/Ia rubra), and the marbled thighs with the 

 X-mark (H. x-signata), but this coincidence is not constant. Beneath 

 whitish, immaculate. Male with an external subgular vocal vesicle. 

 From snout to vent 40 millim.
