34. Phyllodactyltjs microphyllus, sp. nov. 



Small scales of the back and sides with larger ones scattered irregularly among 

 them ; these are not very much larger, not keeled, but smoothly convex, and a 

 little smaller than the smooth, flat belly scales. Gular scales granular ; labials to 

 pupil \. Mental large, convex behind, bounded by four round scales of small 

 size. Scales of top of muzzle twice as large as those of vertex. Tail scales uni- 

 form. Transverse scales of inferior side of the digits rather short; large plates of 

 the end of the toes remarkably small, permitting the ungual phalange to project 

 very freely. A row of prominent scales behind the thighs on each side of the 

 base of the tail. Color very pale, with a few very indistinct transverse shades ; in 

 the young these shades are cross-bars.

From the valley of Jequetepeque, Peru. 



This species is intermediate between the last described, P. incequalis, and such 

 species as the P. reissii in the character of the squamation. In the small size of 

 its distal lamina? of the digits, it differs from all the other species, and approaches 

 the Australian genus Stenodactylopsis of Steindachner.
