a point in the El Chico National Park probably less than 2 miles from 
the exact type locality, but at a somewhat higher elevation. They 
were found under piles of chips and under rotting leaves, usually in 
well-shaded places. 
BOLITOGLOSSA XOLOCALCAE Taylor 
Bolitoglossa xolocalcae Tayutor, Univ. Kansas Sci. Bull., vol. 27, pt. 1, No. 8, 
1941e (December), pp. 148-150, pls. 7, 9, figs. 7-8 (Cerro Ovando, Chiapas, 
México, 6,800 to 7,100 feet elevation). 
The type series, U.S.N.M. No. 111871 (type) and U.S.N.M. Nos. 
111372-111470 (paratypes), are in the collection, secured April 16-17, 
1940. 
A total of 345 specimens of Bolitoglossa xolocalcae was collected, all 
on Mount Ovando, Chiapas. Occurring on the same mountain is a 
second, larger salamander, Bolitoglossa nigroflavescens. Both forms 
were found exclusively in bromelias during the dry season (April 
15, 1940). The smaller form, B. zolocalcae, ranged from about 5,400 
feet to the summit (7,100 feet), the greatest concentration occurring at 
about 6,800 feet. Here they were exceedingly numerous, occurring 
in practically all bromelias. In one plant 34 were found. At 6,000 
feet the two species occurred with about equal frequency, but B. 
mgroflavescens was not taken above 6,800 feet or below 5,700 feet. 
Only a few B. xolocalcae were found below 5,700 feet; a single specimen 
was taken as low as at 5,400 feet. 
The distribution of these species is to some extent dependent upon 
the distribution of bromelias. Three general types of bromelias occur 
in the salamander area of Mount Ovando—a small, a medium-sized, 
and a large form. B. nigroflavescens was found almost exclusively in 
the largest bromelias, rarely in the medium-sized form, never in the 
small. B. xolocalcae occurred in the large and medium-sized bromel- 
ias, but only a single specimen came from the small species. Its pref- 
erence, however, was marked for the medium-sized plant. 
The distribution of the two larger plant species corresponds with 
that of the two salamanders. The small bromelia occurred from 3,500 
feet to the peak, but was a smooth, soft-leaved species. While offering 
ample room, it held very little water, and perhaps for this reason it 
was not frequented by the salamanders.

Bolitoglossa nigroflavescens TAYLOR, Univ. Kansas Sci. Bull., vol. 27, pt. 1, No. 8, 
1941e (December), pp. 150-152, pls. 8, 9, figs. 9-10 (Cerro Ovando, Chiapas). 
The following numbers are cataloged: U.S.N.M. Nos. 111169 
(type); 111153-111168, 111170-111192 (paratypes). 
A total of 58 specimens was collected on April 16-17, 1940, all on 
Mount Ovando, Chiapas, between 5,700 feet and 6,800 feet elevation, 
a zone that corresponds to the distributional zone of a large bromelia. 
The vertical distribution of this species is discussed under B. xolocalcae.
