teriorly; these are bordered laterally by two lighter brown or reddish- 
brown stripes, which continue back two-thirds the length of the side 
and are occasionally connected by a light irregular stripe across the 
rump. The limbs are barred, the bars sometimes merely stippled 
lines or stripes. A well-defined, elongate, irregular, black spot from 
eye above tympanum to behind axilla. It is variable in color on the 
venter and under limbs, sometimes clouded, rarely nearly cream 
white, but oftener speckled or stippled black on a light or clouded 
surface. 
The maximum size in mm., as shown by this representative series, 
is 77 in females, while 10 measured from 70-74. The maximum in 
males is 71, while three others measured from 65 to 70. It is known 
to reach a length of 83 mm. 
The distribution from San Luis Potosi to southern Chiapas gives 
this form a rather large known range. In Chiapas it is largely re- 
placed by another species of the genus which is here described. A 
third, much larger form, being described elsewhere, occurs in Guerrero. 
During the dry season specimens were frequently encountered in 
bromelias and on banana plants; at Pujal the single specimen was 
ensconced in a rotten log. 
The specimens from Veracruz when captured secreted copiously 
a white viscous substance, which dried quickly and adhered to any 
object touching it. In contact with the mucous membranes of the 
nose the secretion caused violent sneezing, and other symptoms of 
a severe cold, lasting two to three hours. Occasionally such symp- 
toms appeared before there was any possible chance of direct trans- 
ference of the secretion to the nostril. The secretions that adhered 
to collecting sacks produced an effect as long as two or three days later 
as the sacks were used for other specimens.

Diagnosis.—A small member of the genus, the known maximum 
size (15 specimens) 70 mm. Related to mgropunctata but lacking 
distinctive markings, having larger terminal pads on tips of digits, 
narrower head, the eye larger, its diameter greater than its distance 
from the nostril, and with a widened, bifid, subarticular tubercle
