digital expansions with other characters of the P. microphyllus* render 
comparisons with it unnecessary. From the nearer P. inequalis} it differs 
primarily in three features : (1) the greater relative size of the tubercles ; 
(2) the differently arranged infralabials, and (3) in the longer digits.

21. CHOROPHILUS CUZCANUS sp. nov. 
A species of medium size in a genus where the species are never large. 
Form rather robust, head wide, flat; canthus rostrales well marked but 
contracted. Nostrils near the end of the muzzle, which is obtusely rounded. 
Tympanum distinct, its diameter half that of the eye slit, which is nearly 
as long as the muzzle in front of it. The limbs are rather elongate, and 
the digital dilatations are quite small. The wrist of the extended fore 
limb reaches the end of the muzzle, and the elbow is slightly overlapped 
by the knee when both are appressed. When the hind limb is extended 
forwards, the heel reaches to the line of the front of the orbit. There are 
no tubercles on the sole, and the skin of the superior surfaces of the body 
is smooth, while that of the thorax and abdomen is closely areolate. 
The vomerine teeth are in two full and closely approximated fasicles 
between the internal nares, their posterior borders projecting a little 
behind the posterior margins of the latter. The nareal openings are small, 
and about equal to the ostiapharyngea ; the tongue is discoid, and is openly 
notched on the posterior freedorder, which constitutes about one-third the 
length of the organ. 
Color of the upper surfaces dark olive; of the limbs paler; the femur 
uniform light olive, posteriorly. Inferior surfaces dirty white, except 
those of the thighs, which are pale yellow. Sides of the head to the tym- 
panum dark, bordered above by a blackish line along the canthus rostralis, 
and below by a light labial border.
