Hylodes podiciferus, Brocchi, Miss. Sc. Mex., Batr. p. 56. 
Tongue oval, slightly nicked behind. Yomerine teeth in two 
small oblique series behind the choanz. Snout subacuminate, as 
long as the orbital diameter; nostril much nearer the tip of the 
snout than the eye; interorbital space broader than the upper eye- 
lid; tympanum distinct, two thirds the diameter of the eye. Tips 
of fingers and toes scarcely dilated. The hind limb being carried 
forwards along the body, the tibio-tarsal articulation reaches beyond 
the tip of the snout. Skin smooth. Four varieties of colour are 
distinguished by Cope. The present specimen is greyish, marbled 
with brown; sides of head and of front part of body, and a cross bar 
between the eyes, dark brown; a light vertebral line; hind limbs 
cross-barred.

The shorter hind limbs (the tibio-tarsal articulation reaching the

vomerine teeth, distinguish this form from 1. podiciferus.
