 Hylodes podiciferus, BroccM, Miss. So. Mex., Batr. p. 56. 



Tongue oval, slightly nicked behind. Vomerine teeth in two 

 small oblique series behind the choanae. 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 aro 

 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.

p. 108. 

 Hylodes murioinus, Brocehi, Miss. Sc. Mex., Batr. p. 56. 



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

 tip of the snout_) and larger tympanum (the size of which equals 

 that of the eye), with the more transverse and widely separated 

 vomerine teeth, distinguish this form from H. podiciferus.
