through the skin corresponding to their position cannot be- 

 detected. The ear-openings are distinct, two mm. in diameter, 

 though almost completely concealed by the fur which grows right 

 up to their margins. The aperture is surrounded by a ring-like fold 

 of the integument, which very slightly raises its margin above the 

 level of the surrounding skin, and in the interior of the meatus 

 are thickly-set vibrissse. Its position is 15 mm. behind and 

 above the angle of the mouth, measured along a line which would 

 continue the normal direction of the mouth-slit backwards. 



The tail is peculiar. Hard, tough, leathery in texture and 

 appearance for the greater part, it is marked with conspicuous 

 annular ridges to the point. Thick at its insertion, it tapers to a 

 blunt or even knob-like tip. On the dorsal surface, the soft fur 

 of the body extends over it for about half its length, but the 

 ventral and lateral surfaces are bare nearly to the anus. At 

 about its middle there are two lateral projections or tuberosities, 

 which give increased width to the tail in that position, causing it 

 to be there even wider than at the point of its insertion. This is 

 particularly marked in one specimen, but in all, indications of the 

 same peculiarity exist. The vent is margined by a ring of very 

 long, straight hairs. 



The limbs (PI. II., III., IV.) are short and strong, the fur ex- 

 tending down to the manus and pes respectively. The fore-limb 

 terminates in a manus of most peculiar construction, the structure 

 of which is so distorted that it can hardly be understood without 

 previous reference to its osteology, and in the absence of this I 

 fell into error as to the order of the digits in my first descrip- 

 tion. It is so folded, that when seen in the position assumed 

 by the preserved specimen, the two large conspicuous claws of the 

 third and fourth digits conceal all the other parts from view, except 

 the blunt and broad horny nail of the fifth, which is seen project- 

 ing at the posterior part of the base of the fourth. On the inner 

 side of these, and separated from them by a deejD cleft, which opens 

 inf eriorly and posteriorly, is a tough, leathery and much wrinkled 

 palm, from which emerge the slender claw-like nails of the 

 pollex and second digit. Thus, owing to this folding of the hand, 

 the digits may be described as consisting of two rows with a cleft 

 between them ; the outer comprising the third, fourth, and fifth, 

 and the inner the first and second. The wrinkled and baggy 

 palm, corresponding to the latter two, covers them on their outer 

 surface as far as the roots of the claws ; posteriorly it overlaps 

 them, and extends upwards to the base of the short nail of 

 the fifth digit. On tlie dorsal surface of the hand, which faces 

 inwards, the outlines of the first and second digits are evident, 

 and the fur, here thin and sparse, extends only to the meta- 

 carpal region. The claws of these two are long, slender, narrow
