MEXICAN AMPHIBIANS—TAYLOR AND SMITH 599 
Genus DIAGLENA Cope, 1887 
DIAGLENA RETICULATA Taylor 
Diaglena reticulata Taytor, Univ. Kansas Sci. Bull., vol. 28, pt. 1, No. 4, May 15, 
1942b, pp. 60-61, pl. 4, figs. 1, la, 1b, 1c, pl. 5, fig. 1 (Cerro Arenal, Oaxaca), 
The type, U.S.N.M. No. 115500, was discovered on January 2, 
1938, by Thomas MacDougall at Cerro Arenal, 30 km. northwest 
of Tehuantepec, Oaxaca. 
Both forms of this genus appear to be terrestrial. The type of 
reticulata was captured in a terrestrial bromelia, while Diaglena spa- 
tulata has usually been found on the ground. 
Genus AGALYCHNIS Cope, 1864 
AGALYCHNIS CALLIDRYAS (Cope) 
Hyla callidryas Corr, Proc. Acad. Nat. Sci. Philadelphia, vol. 14, 1862, p. 359 
(Panamé4). 
Agalychnis callidryas Corr, Nat. Hist. Rev., 1865b, p. 110. 
A single specimen, U.S.N.M. No. 116042, taken at Santo Tomas, 
Tabasco, June 24, 1939, is referred to this species. The presumed 
distinctions between this species and Agalychnis helenae Cope are not 
great. This latter species has a purplish lateral stripe that is crossed 
by five diagonal cream lines, which touch a longitudinal cream line 
bordering the purple stripe above. A. callidryas lacks the longitu- 
-dinal cream line but does have the diagonal lines. There is a green 
stripe of varying width on the dorsal surface of the femur in callidryas 
and it is also present in the type of helenae. Whether these forms are 
actually specifically distinct may be questioned. This specimen was 
taken from a bunch of orchids high in a large tree. 
AGALYCHNIS DACNICOLOR (Cope)

Agalychnis dacnicolor Corr, Journ. Acad. Nat. Sci. Philadelphia, ser. 2, vol. 6, 
1866a, p. 86. 
A typical specimen, U.S.N.M. No. 116040, was taken on August 
31, 1939, at night, at Tierra Colorada, Guerrero, by following its 
call. U.S.N.M. No. 116041 is from Tehuantepec, Oaxaca, taken in 
March 1940, and is the first record for that state. The latter speci- 
men has the tips of the digits narrowed, as in all other juveniles. 
AGALYCHNIS MORELETIL (Duméril)

Hyla moreletit DuméniL, Ann. Sci. Nat., Paris, ser. 3, Zool., vol. 19, 1853, p. 169 |
