MEXICAN AMPHIBIANS—TAYLOR AND SMITH 569 
Skin more or less rough above when examined under a lens; sides 
distinctly granular; venter completely smooth; inguinolumbar gland 
absent or concealed; no discernible axillary gland; the greater part of 
the under surface of femur, and part of the posterior face, granular; 
loréal region with small pustules, and the snout likewise; a faint median 
ridge the length of the body. 
Color.—Ground color cream with numerous small brown spots or 
irregular flecks, more or less equally distributed on head, body, and 
sides; spots sometimes confluent; venter light but lightly pigmented 
except for a narrow medial area on abdomen; arms and legs barred, 
but the bars broken up into smali spots; the upper lips barred. 
Measurements in mm.—U.S.N.M. No. 116509 (type), E.H.T.- 
H.M.S. No. 29807, U.S.N.M. No. 116511. Sex, 9, 2, o&; snout to 
vent, 42.5, 40, 33; width of head 16.5, 15, 12.5; length of head, 18, 
16.8, 138; arm, 29, 26.2, 24; leg, 68, 61, 53.5; tibia, 23.5, 21.8, 19.5; 
foot, 28.2; 26.5, 23.6. 
Variation.—The tympanum (2.38 mm.) in the largest male is a little 
more than the half of the eye diameter (4.2 mm). There is a little 
difference in the relative size of the vomerine tooth groups and the 
choanae, or their position with relation to each other. One or two 
of the specimens have the series a little closer together than in the 
type. 
The toes show practically no trace of web at their bases and the 
lateral edges have only a very faint trace of a lateral ridge. (In 
alfred. there is a small remnant of a web between the bases of the toes, 
and the edges of the digits have strong lateral ridges or narrow fringes 
to the disk.) The males are very much smaller than the females. 
The recently described Hleutherodactylus cucanebi Stuart, from Alta 
Verapaz, Guatemala, is related. The species have totally different 
color patterns, and the present one is considerably larger since the 
type of zucanebi is a fully adult female and is only of the size of the 
male in this species. HH. xucanebi is a mountain form, coming from 
an elevation above 4,000 feet, while the present species is a foot- 
hills form (500 feet). 
Remarks.—-Specimens of the isips: series were found at night sitting 
on vegetation a few feet above the ground.

No. 14, Nov. 15, 1942d, pp. 299-301, pl. 25, figs. 5-8, pl. 27, fig. 10 (4 miles 
north of Tianguistengo, Hidalgo). 
A single specimen is in the collection from Tequeyutepec, Veracruz 
(U.S.N.M. No. 116490), collected March 23, 1940. It is a male with 
greatly elongated vocal slits. | 
The specimen measures 29 mm. from snout to vent, which is ap- 
proximately the size of the type. On the occiput are two small black
