Hab. Easrern Costa Rica (Cope: Bull. U.S. Nat. Mus. no. 32, p. 18), Las Delicias, 
Santa Clara (alt. 400 met.).—Tropicat SourH AMERICA. 
Vomerine teeth in two arched series behind the choane. Snout rounded, with the 
canthus rostralis rather obtuse. Tympanum two-thirds or more the size of the eye. 
Toes not fringed. Two small metatarsal tubercles, the outer one being often absent in 
young specimens. Skin smooth, generally with large glandular patches on the sides; 
a glandular fold on each side of the back; abdominal disk more or less indistinct. 
Coloration subject to great variation: generally greenish-brown above, with transverse 
rows of black spots; lips without white stripe. Hind limbs cross-banded; thigh 
marbled with blackish and yellow behind. Male with a strong conical spine on the 
inner side of the first digit, and with another bi- or tricuspid one on each side of 
the breast. 
Common and widely distributed as this species is in Tropical South America, it does 
not seem to extend northwards beyond Costa Rica, where it is perhaps scarce or local. 
I have seen only one very young specimen (body 36 millim. long) from that country ; 
it is peculiarly coloured, very like an example of the same size from Ecuador in the 
Natural History Museum. The lower parts, sides of the body, and limbs are deep 
black ; lower parts of the body and limbs with small round milky-white spots. Upper 
parts of the body purplish-grey ; interorbital space and anterior part of the back each 
with one, the snout with two, black cross-bands. ‘Two black longitudinal bands start 
from the eye, the upper one running along the side of the back to the middle of the 
pelvis, the second obliquely descending above the tympanum towards the abdomen ; 
canthus rostralis with a black stripe; three black triangular spots on the upper lip. 
Upper parts of the limbs not banded.
