MEXICAN AMPHIBIANS—TAYLOR AND SMITH 589 
HYLA ROBERTSORUM Taylor 
Hyla robertsorum Tartor, Univ. Kansas Sci. Bull., vol. 26, 1939 (Nov. 27, 1940e), 
pp. 393-396, figs. 5-6 (El Chico National Park, Hidalgo). 
A fine series of 59 topotypic specimens was secured by the two of us 
on September 17, 19389 (U.S.N.M. Nos. 114762-114786). These, 
like the original type series, were found on plants at the edge of a 
stream. ‘There were many young specimens, some bright green in life. 
Frequently the young were found basking in the sun on leaves over- 
hanging the stream. 
HYLA BISTINCTA Cope 
Hyla bistincta Cops, Proc. Amer. Philos. Soc., vol. 17, 1877, p. 87 (probably 
Veracruz). 
Fifteen specimens were secured at the following localities: Mpx- 
Ico: 20 km. west of Villa Victoria, March 6, 1939, U.S.N.M. No. 
114518. Micuoackn: Uruapan, March 11-12, 1939, U.S.N.M. Nos. 
114514-114524. Veracruz: Mountain southwest of Acultzingo, 
March 17, 1940, U.S.N.M. No. 114525. The first specimen listed 
(a juvenile) was found under a stone in a grassy flood plain of a small 
stream. At Uruapan they were found in banana plants, protected by 
the thick outer sheaths of the trunk. Above Acultzingo, Veracruz, a 
single specimen was found in a bromelia. The latter is much more 
distinctly marked than the others. In life the colors were described 
as follows (Smith, field notes): ‘‘General dorsal ground color a rich, 
creamy-slate; marking on side of head dark purplish brown; light 
areas on sides of abdomen creamy white, except a pale green tint in 
axilla and groin; latter color dimly visible along lower portion of sides 
of body; anterior surfaces of entire hind leg somewhat greenish, less so 
on anterior surface of arms; light areas of concealed surfaces of thigh, 
ereenish.”’ 
The tarsal fold is more distinct in the eastern specimens than in the 
western; and the elongated anal flap, although having the median ver- 
tical groove, 1s somewhat less crenelated on the posterior border. 
HYLA PHAEOTA Cope 
PLATE 26 
Hyla phaeota Cort, Proc. Acad. Nat. Sci. Philadelphia, vol. 6, 1862, pp. 8358-359 
(Turbo, Colombia).—Taytor, Univ. Kansas Sci. Bull., vol. 28, pt. 1, No. 5, 
May 15, 1942c, pp. 80-81, pl. 8, figs. 1, la, 1b, 1c. 
A series of 11 specimens of this species was collected at Piedras Ne- 
eras, Petén, Guatemala, May 28-29, 1939. The cataloged specimens 
are U.S.N.M. Nos. 111139-111147. These were reported by Taylor 
(loc. cit.). 
Specimens were captured at night on the ground at the edge of 
small, temporary pools. As the locality is very close to the Mexican 
border this species must be reckoned as a member of the fauna of 
México.
