On Atlantic slopes 215 specimens of this species were collected, of 
which the following specimens are cataloged in the collection: 
GuaTEMALA: U.S.N.M. Nos. 116899-116900, Piedras Negras, May 21 
to June 21, 1939. Curtapas: U.S.N.M. No. 116901, San Juanito, near 
Palenque, July 16, 1989. Oaxaca: U.S.N.M. No. 116902, Matias 
Romero, January 25, 1940. Veracruz: U.S.N.M. No. 116903, 
116906, Potrero Viejo, December 13, 1938 to January 9, 1939; U.S. 
N. M. No. 116907, Cuautlapan, January 16, 1939. 
In specimens from Potrero Viejo, Veracruz, not far from the type 
locality, the ground color is light clay, fawn, brownish, or pinkish. <A 
black stripe begins on the tip of the snout and runs on the upper part 
of the lores to the eye; behind the eye the stripe is continued as an 
elongate black spot bending about the tympanum The tip of the 
snout is whitish. The lips are not barred with black but there is some 
suggestion of mottling and indistinct lighter dots in some specimens. 
Black spots in front of knee; in two specimens there is a hair-fine 
light median line. There is a black triangular anal spot, and paired 
black spots on the shoulder. The supratympanic fold is moderate, 
not closely approximated to the tympanum posteriorly; and the snout 
in front of nostrils is relatively short. They differ very little in 
structural characters from the Guatemala specimens. 
None of the specimens from central Veracruz are from elevations 
above 2,500 feet. 
The Guatemala specimens from Piedras Negras form a series that is 
more definitely marked and colored, containing many pinkish or 
reddish individuals. However, some of these are grayish, clay- 
colored, or brownish. Of 25 females all except one appear to contain 
large ovarian eggs. Ten of these have a hair-fine, more or less distinct, 
median cream or white line, and white lines running lengthwise on the 
posterior face of the femur, in one case extending the length of the 
tibia to the heel. Two black shoulder spots, rather closely ap- 
proximated, are distinct in all save two specimens. ‘Three are more or 
less brown mottled on the dorsal surfaces. The distinctness of the 
brown transverse bars on the femora varies greatly. 
The side of the head has a black stripe bending down behind the 
tympanum and widening; in front of the eye it reaches almost to the 
edge of the lip anteriorly; the lower part of the loreal region is blackish,
