EXTINCT LEMURS 
also. They are a group which is somewhat inter- 
mediate between the more highly organized monkeys 
and the Insectivora (e.g. shrews, hedgehogs, etc.). 
With grasping hands and feet suitable for climbing and 
handling their food, is combined a crafty and long- 
snouted face, such as that of a fruit bat. The brain, 
that organ by which the higher Primates can be distin- 
guished from the lower, is on a level with animals 
lying lower in the scale, and is not like that of monkeys. 
The Germans appropriately enough signalize this half- 
way character of the lemurs by terming them “ half- 
affen’’; and Dr. Forsyth Major has lately found the 
fossil remains of an animal which he thinks still more 
successfully bridges over the rather narrow gulf separat- 
ing lemurs from monkeys. So much then for the 
relationships of our Hapalemur and of course other 
lemurs. Extreme agility is one of the most conspicuous 
qualifications of this lemur, and of those which are 
most nearly allied to it. Its energy of muscular move- 
ments contrasts greatly with that of the more torpid 
lemurs of West Africa, and of the eastern hemisphere. 
This can be readily witnessed in the cages at the Zoo. 
This rapidity of movement will render it a little diffi- 
cult to inspect a curious peculiarity of Hapalemur, 
almost unique, so far as is known, in the lemur tribe. 
If the animal can be induced to lend itself to scientific 
observation, the visitor may note upon the wrist of the 
male a patch of black spiny structures, which are 
columnar and corn-like outgrowths of hardened skin. 
Inthe lady Hapalemur griseus these outgrowths are not 
present, but in the same place is a patch of black and 
naked skin. Precisely the same kind of structure is to 
be found on the foot, not on the hand, of an African 
lemur not very closely allied to this, and which is known 
as Galago garnettit. What the use of these roughened 
patches of skin may be is not known at present ; obser-
