Snout rather obtuse, slightly projecting, not twice as long as the 
diameter of the eye. Fore limb considerably longer than its distance 
from the tip of the snout. The hind limb being carried forwards 
along the body, the tibio-tarsal articulation reaches the shoulder in 
the female, a little beyond in the male. Toes quite free, with blunt 
tips and distinct subarticular tubercles; a very small inner meta- 
tarsal tubercle; no outer tubercle. Skin smooth; a fold across the 
head, behind the eyes. Brown, dotted with lighter beneath. Male 
with a subgular vocal sac.

Snout pointed, projecting, twice as long as the diameter of the eye. 
Fore limb considerably longer than its distance from the tip of the 
snout. The hind limb being carried forwards along the body, the 
tibio-tarsal articulation reaches in front of the shoulder; toes quite 
free, with blunt tips and distinct subarticular tubercles; a very 
small, very indistinct, inner metatarsal tubercle ; no outer tubercle. 
Skin perfectly smooth; a fold across the head, behind the eyes. 
Light brown above; back with an irregular broad dark band; sides 
of head and body dark brown; hip with a round dark-brown spot ;_ 
thigh, leg, and tarsus each with a broad dark-edged cross band ; belly 
marbled with brown; throat brown, marbled with whitish. 
In coloration this species resembles L.ustwm, from which it differs . 
in having a single, hardly distinct, metatarsal tubercle. From 
E. ovale it differs in the longer hind limbs; and from £. carolinense 
in the latter character and in the longer, more pointed snout.
