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 ; afew small 
tubercles on the knee and onthe heel. Greyish brown above; head 
uniform above; a black, light-edged triangular spot below the eye, 
confluent with a streak of same colour extending from the eye to 
the eud 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.
