Tongue subcircular, a little longer than broad. Anterior vomerine 

 teeth not longer than the others. Snout twice the length of the 

 orbit ; nostrils close together, equally distant from the eye and the 

 tip of the snout ; interorbital space nearly four times broader than 

 the space between the nostrils ; hinder edge of the helmet strongly 

 curved ; the distance from one of the posterior extremities of the 

 helmet to the other equals about twice and one third the distance 

 from one orbit to the other ; profile of the upper lip curved ; tym- 

 panum much larger than the eye, a vertical oval obliquely directed 

 forwards and upwards. Fingers short, first much longer than 

 second ; toes short, webbed at the base ; subarticular tubercles 

 scarcely prominent ; a single, scarcely prominent, metatarsal tu- 

 bercle. The hind limb being carried forwards along the body, the 

 tibio-tarsal articulation reaches nearly the eye. Skin of back 

 smooth ; sides and belly with large tubercles ; a few scattered 

 tubercles on the throat and breast ; three rows of tubercles across 

 the calf; a small triangular dermal flap at the tip of the snout; 

 upper eyelid produced in a horn-like dermal appendage ; a few small 

 tubercles on the knee and on the heel. Greyish brown above ; head 

 uniform above ; a black, light-edged triangular spot below the eye, 

 confluent with a streak of same colour exteuding from the eye to 

 the end of the helmet ; back and sides and upper surface of thighs 

 marbled with dark brown ; arms, legs, and tarsi with narrow dark 

 cross bars ; hinder side of thighs and lower surface of tarsi blackish 

 brown ; round blackish-brown spots on the inner side of the legs ; 

 lower surfaces brown ; a line on the middle of the throat and the 

 tubercles on the belly white.

The frog figured by Espada and Brocchi is evidently different from 

 the true H. scutatus figured by Peters ; it appears to be the same as 

 that described by Cope under the name H. divaricatus. 



The helmet is broader, with more divergent outlines, and its hinder 

 edge is but slightly curved ; the distance between each posterior 

 extremity of the helmet is greater if compared to the width of the 

 interorbital space. Espada describes and figures the tongue as 

 reniform, broader than long.
