Show 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 branchial 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, sharp 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. The external 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 :- Dimensions. • , inches.
