lip. The nostril is a little beliiud the apex, aud as fiir iu fiout of tbe 

 orbit as tbe loug diauieter of the latter. Tympauic membrane roiiiub 

 its diameter about half that of eye. Choante lateral, equal iu size to the 

 ostia pharyngea. Tongue longer than wide, full, entire. Integuments 

 everywhere smooth; on the abdomen a faint discoidal fold. Digits 

 short, moderately expanded and truncate at the extremity. Prom- 

 inent tubercles at the proximal ends of the phalanges below. First and 

 second anterior toes equal and shorter than fourth. The heel of the 

 appressed hind limb reaches the middle of the tympanum, and the ex- 

 tremity of the tarsus a little anterior to the orbit. The fore limb is rela- 

 tively longer, the wrist extending beyond the extremity of the muzzle. 

 The tarsus is two fifths the entire length of the posterior foot. The in- 

 terorbital space is flat and wide, and is but a trifle narrower than the 

 expanse of the sacral diapophyses. 



The color of the upper surfaces is a light parplish-brown, closely 

 spotted with rather small closely placed and broadly defined dark 

 brown spots. The spots are less distinct on the head. Inferior sur- 

 faces light yellowish, immaculate, this tint commencing as small spots 

 on the pale ground of the sides. Limbs above brown, broadly cross- 

 banded with yellowish- femora behind, light brown with a few light 

 points.

Nothing is yet known of the life history of this species. It is prob- 

 able that, like other species of the genus, it inhabits rocky places. I 

 found the S. verrucipes in the bottom of a rocky ravine in the State of 

 Hidalgo^ Mexico^ uuder a stone on the borders of a small stream.
