‘Salto de Agua: U.S.N.M. No. 115479. This specimen is very close 
to the Potrero Viejo specimens. The head is darker, but under water 
the variation between the black lines and the somewhat lighter color 
of the interorbital region is evident. ‘The venter is cream and the 
white labial line continues back on the arm. The labial light line is 
bordered below by a black line. Collected at night. 
La Esperanza: U.S.N.M. No. 115477. Similar to the above. The 
pigment under the tibia is a little thicker, and encroaches more on 
underside of the femora. The skin is rather smooth as in the previous 
specimen, probably due to manner of preservation. There is scarcely 
a trace of a dark line below the labial light line. 
Colonia Hidalgo: U.S.N.M. No. 115478. This specimen seems to 
differ from the typical more than any of the others. There is a dark 
interorbital bar, and there is more pigment everywhere save on the 
median dorsal line, which normally is darker than thesides. Thespec- 
imen was dead when preserved, and the toes are somewhat shriveled. 
The dorsal folds are typical. The cream labial line is bordered be- 
low by a black line. 
MICROBATRACHYLUS MONTANUS Taylor 
Microbatrachylus montanus TAytor, Univ. Kansas Sci. Bull., vol. 28, pt. 1, No. 5, 
May 15, 1942c, pp. 67-69, pl. 6,? figs. 2, 2a, 2b, 2c (Mount Ovando, Chiapas). 
The type, U.S.N.M. No. 115507, a large female, was obtained at 
about 6,000 feet elevation on Mount Ovando, April 15, 1940. Four 
paratypes, U.S.N.M. Nos. 115701 and 115480, La Esperanza, April 
11, 1940; U.S.N.M. No. 115702, Las Nubes, April 15, 1940; and 
K.H.T.-H.M.S. No. 27846, Salto de Agua, April 18, 1940, were also 
collected in Chiapas. 
This species is the largest one known of the genus, the female type 
measuring 27 mm. from snout to vent. 
MICROBATRACHYLUS OAXACAE Taylor 
Microbatrachylus oaxacae TAytor, Univ. Kansas Sci. Bull., vol. 26, No. 15, 1939 
(Nov. 27, 1940g, mailing date), pp. 504-507 (Cerro San Felipe, Oaxaca, 
Oaxaca). 
Two topotypic specimens from Cerro San Felipe, Oaxaca, July 10- 
20, 1940, U.S.N.M. Nos. 115444 and 115445, and a third specimen, 
U.S.N.M. No. 115443, from Lachiguiri, Oaxaca, January 20, 1940, 
are in the collection. 
The feature by which this form may be most readily distinguished 
is the presence of an outer palmar tubercle. The limb is longer, and 
the tibiotarsal joint reaches beyond the snout. |
