1869. | THE MYOLOGY OF MENOPOMA, 255 
Two large cutaneous folds (each much convoluted and like a frill) 
extend backwards, one along each side of the body, from the arm-pit 
to a little behind and above the root of the pelvic limb. 
A marked fold on each side of the neck projects round the bran- 
chial orifice, and is continued backwards from its upper border 
towards or over the root of the pectoral limb. 
The antero-posteriorly elongated cloacal aperture is placed just 
behind, and not between, the pelvic limbs. Its circumference 
(which is of a lighter colour than the rest of the skin) is thrown into 
numerous small, sbarp folds. 
The proximal and distal divisions of each arm and leg (i. e. the arm 
and forearm and the thigh and leg respectively) are subequal in length. 
The posterior digits are very broad, through cutaneous expansions. 
The pectoral limb when turned forwards does not attain the angle 
of the mouth, nor when turned backwards does it even nearly meet 
the pelvic limb turned forwards. 
A cutaneous fold extending along the margin of each jaw serves 
as a lip. 
ihe cxtéraal nostrils are very small and simple apertures close to 
the end of the muzzle. 
The eyes, as is well known, are very small and quite destitute of 
eyelids. 
The gape of the mouth extends backwards beyond the eye. 
The head is very flat, without ridges or any marked concavities or 
convexities. A shallow, rather ill-defined, longitudinal depression 
runs along the middle of the back. The size and proportions of the 
specimen are as follows :—
