MEXICAN AMPHIBIANS—TAYLOR AND SMITH 547 
A single specimen shows a pattern similar to that of the figure given 
by Duméril and Bibron (1854, pl. 104, fig. 1). On the lines of contact 
of dark and light color on the back, there is a fine white (or lighter) 
edge. 
The dorsal surface of the tail may be nearly uniform light, with few 
dark spots, or strongly cross-barred, or heavily reticulated or even 
stippled with black, but is seldom lined. 
BOLITOGLOSSA FLAVIVENTRIS (Schmidt) 
Oedipus flaviventris Scumipt, Publ. Field Mus. Nat. Hist., zool. ser., vol. 20, 1936, 
pp. 148-150, fig. 17 (Chicharras, Chiapas). 
Seventy-two specimens were collected from April 5 to June 3, 1940, 
at La Esperanza, Chiapas, of which U.S.N.M. Nos. 116367-116381 
are cataloged. 
All but two of this series were caught at night. One of the excep- 
tions was a large female found deep in a rotten log. The specimen 
seemed to have been there some time, although it was in good condi- 
tion, for it was somewhat stiff and moreover well caked with particles 
of rotten wood. Since the season was extremely dry (May), seven 
months having passed without rain, this example may have been 
estivating. 
The other specimens had obviously been forced to the moist places 
during the dry season. They were found crawling about at night on 
the vegetation at the very edges of a small stream. ‘They preferred 
the large-leafed plants of the genus Calladium, since they apparently 
hid in the axils of the leaves during the day, as evidenced by one speci- 
men found in such a place. They were not disturbed by lantera light, 
and were easily picked up. 
Of two females examined, one had 39 ovarian eggs, 17 on one side, 
22 on the other; the second female, somewhat larger, had 58 eggs, 26 
on one side, 32 on the other.
