This specii^s has a superficial resemblance to the P. oregonensis, but 

 its manifold differences are easily perceived. 



The form is quite robust, and the head is large, its width going into 

 the length to the thighs only fi^ve times. The tail is very much com- 

 pressed from the base, and is also shallow ; its length equals the dis- 

 tance from its base to the gular fold. The legs are robust, but not very 

 long; when appressed to the side they fail to meet by the length of the 

 posterior foot. 



The tongue is large, filling the floor of the mouth. The vomeropala- 

 tine teeth are in two short series, which converge backwards, without 

 coming into contact, from behind the internal eye of thechoana3. The 

 parasphenoid teeth are in a single undivided patch, which commences 

 well behind the vomeroi)alatines. The maxillary and mandibular teeth 

 are minute.

The head viewed from above is oval; in profile the muzzle is thick 

 and truncate, and projects beyond the mouth. The edge of the lip is 

 slightly angulate below the nares. The eye is rather large, its length 

 equaling that of Ihe muzzle. The distance between the nostrils isequa 

 to that between the bases of the ejelids at their middles. The toes 

 are short and free, one phalange of the first digit on each foot project- 

 ing. The ends of the toes are obtuse and bulbiform. A gular fold. 

 Lateral folds fourteen.
