Tibia 2.0 cm. 
Leg and foot 6.7 cm. 
Form.— Head . Width greater than the distance from snout to 
es invisible from ventral view. Nares half way between 
anterior corner of eye and end of snout. Distance between nares 
much greater than interorbital width. Tongue as in R. cantabri¬ 
gensis. Group of vomerine teeth small and oblong. Tympanum 
smaller than eye. A distinct notch on each side of symphysis of 
the lower jaw. 
Body. Stout; dorso- lateral fold-lines eery distinct. Back, Hanks, 
and lower belly smooth. 
Fore legs. One tubercle on the palm. One tubercle each on the 
first, second, and fourth digits. Two tubercles on the third digit. 
First, second, and fourth fingers equal. Hind finger about half as 
long again as others. 
Hind legs. Posterior ventral sides of femora only granulated. 
Web much broader than in R. cantabrigensis , in the majority of 
specimens examined, not curved. 
The broader web, perhaps in part a secondary sexual character, 
is more prominent during the breeding season. A large tubercle on 
the inner side of the foot, and a small one on the outer side and on 
the under side of digital joints. Legs thick and short, much more 
so than in R. cantabrigensis cantabrigensis. Tibia slightly over 
one third the length of the body. Distal joint of tibia reaching 
orbit. First toe equal to first joint of the second toe. Second toe 
reaching one half the way up the second joint of the third toe. 
Third toe reaching to the third joint of the fourth toe. Fourth 
longest. Fifth nearly equal to the third toe. 
Color. — Dorsal surfaces. Dark brown to pale yellowish gray. 
Head with a vitta through the eye and on each side behind the eye, 
including the tympanum and extending forward as a broad line 
from the corner of the eye through the nares to the snout. A light 
line extends from the end of the snout to a point above the axilla; 
other parts of the head faintly marked with darker. A light 
median dorsal line from snout to anus present in many specimens.
