MONKEY HAND-PRINTS 151 
hand. But in some at least of their allies, the lemuroids, 
as represented by the true lemurs of Madagascar, the 
galagos and pottos of Africa, and the lorises and tarsier of 
Asia, a very curious departure from this arrangement 
obtains. In regard to the true lemurs, it is generally stated 
that on the outside of the palm of the hand and under the 
base of the fingers are situated fleshy pads, giving them 
greater grasping power. This, however, is scarcely an 
adequate statement of the true state of the case. Fig. C 
shows the palm-impression of the red-fronted lemur, a well- 
known Malagasy species. In this it will be seen that the 
balls of the digits are expanded into large convex circular 
pads upon which are a number of papillary ridges; but 
instead of these ridges covering the whole surface of the 
pads, they are interrupted by an irregular network of 
relatively large canals, producing the white lines in the 
impression. On the palm of the hand are seen the three 
interdigital eminences of the monkey’s hand, together with 
a large radial and a somewhat smaller ulnar eminence. 
The radial eminence is, however, divided into two portions 
by a deep groove, and on all five eminences are observable 
the usual papillary ridges and grooves traversed by the 
aforesaid irregular network of grooves. On the palmar 
aspect of the second joint of the fingers, and on such 
portion of the centre of the palm as exhibits an impression, 
the papillary ridges, instead of being uniformly distributed 
in regular lines, are restricted to certain small pustule-like 
eminences, on which, however, the linear arrangement is 
distinctly visible with the aid of a lens. And if it had 
been possible to obtain an impression of the basal joints 
of the fingers, a similar pattern would doubtless have 
been noticeable there also, Whether the curious arrange- 
ment of canals characteristic of the palm of the red-fronted
