Third part. Containing the Batrachians in the collection made by J. H. 
Clark, Esq., under Col. J. D. Graham, on the United States and Mexican 
Boundary. 
AMBLYSTOMA PROSERPINE, B. and G. Head eval, longer than broad. Limbs 
and toes well developed. Posterior legs a Jittle shorter than the anterior ones. 
Tail somewhat compressed, tapering ; shorter than the body and head together. 
Five inches in length fromthe end of the mouth to the tip of the tail; head one- 
eighth of this length. Body nearly cylindrical, more so in the male than in the 
female. 
This species is related to A. mavortiam, which it resembles in coloring, but it 
differs from the latter in having a proportionally longer head, and longer limbs 
and toes. The tail, however, is shorter. 
Six immature specimens were obtained at Salado, four miles from San Antonio, 
Texas. Specimens nearly full grown were collected by R. H. Kern, Esq., of 
Philadelphia, onthe route from Montgomery, Mexico. 
Rana areouata, B. and G. Head very large, sub-elliptical ; snout prominent, 
nostrils situated half way between its tips and the anterior rim of the eyes, which 
are proportionally large. ‘The tympanum is spherical, and of medium size; its 
central portion is yellowish-white, whilst its periphery is black. The body is 
rather short and stout; the limbs well developed; the fingers and toes very 
long without being slender. The ground color of the body and head is yellowish- 
green, marked with dark brown. Besides there are from thirty to fifty brown 
areolz, margined with a yellowish line. The upper part of the limbs isof the 
same color as the body, but. instead of areola, transverse bands of brown are 
seen on the hind ones. The lower part of the head and body is yellowish, with 
small dusky spots along the margin of the lower jaw, and under the neck. 
A specimen three inches and a half long was found at Indianola, anda small 
one on the Rio San Pedro of the Gila. 
Boro punctatus, B. and G. Head short, sub-triangular; upper surface even. 
Two inches in total length. Body and upper portion of the limbs covered with 
minute red tubercles. Color of a uniform yellowish-green or yellowish-brown, 
punctured with red on the head, on the upper part of the body and limbs. Be- 
neath yellowish, with occasional minute dots under the head and on the breast. 
Caught on the Rio San Pedro of the Rio Grande Del Norte. 
Buro GranuLosus, B. and G. This species is closely related to the preceding, 
from which it can be distinguished by a larger and more triangular head, whose 
upper surface presents a widely open groove, extending from the occiput to the 
snout, where it terminates in a very narrow channel. The upper periphery of 
the orbits is thus surrounded with a carina which extends from the eyes to the 
nostrils below. The body is covered with very conspicuous tubercles. The 
limbs are rather slender. The ground color is brown, maculated or marbled 
above with black patehes and dots. Unicolor beneath. 
One specimen was collected on the route between Indianola and San Antonio, 
Texas.
