MEXICAN AMPHIBIANS—TAYLOR AND SMITH 587 
HYLA EBRACCATA Cope 
Fieure 60, H 
Hyla ebraccata Corr, Proc. Acad. Nat. Sci. Philadelphia, vol. 26, 1874, p. 69 
(Nicaragua). 
Hyla leucophyllata Taytor, Univ. Kansas Sci. Bull., vol. 28, pt. 1, No. 5, May 
15, 1942c, p. 80. 
A series of five specimens was collected at Piedras Negras, Petén, 
Guatemala, June 3-10, 1939 (U.S.N.M. Nos. 111148-111152). 
These were reported by Taylor (loc. cit.) as belonging to Hyla leuco- 
phyllata. We believe they are more correctly referable to Hyla 
ebraccata Cope, originally described merely as a ‘“‘color variety’ of 
Hyla leucophyllata, but apparently meriting a specific designation. 
HYLA RICKARDSI Taylor 
Hyla rickardsi Taytor, Univ. Kansas Sci. Bull., vol. 25, No. 17, 1988 (July 10, 
1939b), pp. 385-888, pl. 41, figs. 1-8 (Potrero Viejo, Veracruz). 
Of 40 specimens, a series of topotypes, U.S.N.M. Nos. 108675, 
114731-114736, is from Potrero Viejo, September 26, 1939, and 
U.S.N.M. Nos. 114711-114730 are from Palma Sola, Veracruz, 
January 8, 1939. The two series agree and are in every way typical. 
HYLA LOQUAX Gaige and Stuart 
Hyla loquazx GaigE and Stuart, Occ. Papers Mus. Zool. Univ. Michigan, No. 281, 
1934, pp. 1-3 (Ixpuc Aguada, north of La Libertad, El Petén, Guatemala). 
A series of 33 specimens is from the vicinity of Piedras Negras, 
Guatemala, June 3-10, 1989 (U.S.N.M. Nos. 114609-114641). 
Most of the specimens were found at the edge of a small lake, locally 
known as Pozo de la Jicotea. The bright reddish coloration of the 
post femoral region is typical. 
HYLA ROZELLAE Taylor 
Hyla rozellae TayuLor, Univ. Kansas Sci. Bull., vol. 28, pt. 1, No. 5, May 15, 1942c, 
pp. 78-79 (Salto de Agua, Chiapas). 
The type and paratype series, U.S.N.M. Nos. 115039 (type), 
115030-—115038, 115040-115055, are the only known _ specimens. 
This form, a species perhaps related to Hyla loquaz and rickardsi, has 
a reduced axillary web and the vocal sac is absent. 
Specimens were taken at Finca Judrez, May 8-10, 1940 (U.S.N.M. 
Nos. 115052-115055), at Salto de Agua, 1,200 feet, April 18, 1940 
(U.S.N.M. Nos. 115038-115051), and Las Nubes, 2,900 feet, April 18, 
1940 (U.S.N.M. Nos. 115038-115051), on Mount Ovando near Escu- 
intla, Chiapas. All were found sitting on vegetation at the edge of 
small, steeply inclined streams. None was heard calling and, in fact, 
only a single adult, the type, was found. All the other specimens 
are recently transformed or half grown.
