NOTES ON A COLLECTION OF BATRACHIANS AND REP¬ 
TILES FROM CENTRAL AMERICA. 
Dr. D. A. Atkinson. 
It has been the privilege of the writer to look over a small 
collection of Batrachians and Reptiles made in Central America 
during January and February of 1905 by E. B. Williamson, 
Jas. S. Hine and Chas. Deam. There are seventy-two specimens 
in the collection, sixty-eight of which were collected in Guate¬ 
mala, two in British Honduras, and two in Honduras. 
Seven frog larvae and one young snake could not be deter¬ 
mined specifically on account of their immaturity and the lack 
of descriptions of the young of the Central American species. 
The eighteen specimens of Batrachians represent four genera 
and seven species (including the undetermined Rana sp.); the 
fiftv-four specimens of Reptiles represent twelve genera and 
seventeen species. While none of the specimens present any 
great variations from the descriptions published, still there were 
a number of minor variations noted and recorded in the following 
notes. The known geographical range of several species is con- 
siderably extended by this collection. The measurements and 
some of the scale formulae are given with most species of reptiles, 
as there is a lack of information along these lines. 
BATRACHIA. 
BUFO. 
This genus is represented by six specimens, belonging to two 
species; all the specimens being adults except one. 
(а) Bufo marinus (specimens No. 3 and 36). This is the large 
brackish waterspecies, being one of the largest species of thegenus, 
with very large and prominent parotid glands. No. 3 was collected 
at Gualan, Guatemala, Jan. 13, 1905; No. 36 was collected at 
Los Amates, Guatemala, Feb. 25, 1905. Both specimens are 
full grown and show the characteristic parotid development, but 
have much smoother skin than the specimens of the same 
species from the South American coast. 
(б) Bufo valliceps. (Specimens No. 29, 51, 55, and 63.) 
No. 29, collected at Gualan, Guatemala, Jan. 16, 1905, 
is an adult specimen, typical coloration, and with very prom¬ 
inent tubercles for this species; No. 51 was collected at Los 
Amates, Guatemala, Feb. 25, 1905, adult specimen with very 
dark coloration; No. 55 was collected at Gualan, Guatemala, 
Jan. 13, 1905, adult, coloration and tubercles typical; No. 63, 
was collected at Gualan, Guatemala, January 13, 1905, and is a 
very young specimen, in. in length. The bony ridges on the 
head of No. 63 are very slightly developed, but the coloration 
and the tubercles are very similar to those of the adult.
