QUADRUMANA.

Geoffrey’s Potto ( Lemur potto, Lin. ; Galago Gruniensis, Desm. ; 
P. Geoff royi, Ben.) — From Sierra Leone; a slow-moving and retiring 
animal, which seldom makes its appearance but in the night-time, 
and feeds on vegetables, chiefly the Cassada.] 
The Galagos {Otolicnus, Illig.) — 
Have the teeth and insectivorous regimen of tlie Loris ; the 
tarsi elongated, which gives to their hinder limbs a dispro- 
portionate extent ; tail long and tufted ; large membranous ears 
[which double down when at rest, as in some Bats] ; and 
great eyes, which indicate a nocturnal life. [The index, as well 
as the thumb of the anterior hand, inclines in some to be op- 
posable to the other fingers.] 
Several species are known, all from Africa ; as the Great Galago {Galago 
crassieaudatus, Geof.), as large as a Rabbit ; and the Senegal Galago (G. 
Senegalensis, Geof.), the size of a Rat. The latter is known as the Gum 
animal of Senegal, from its feeding much on that production. [These pretty animals have at night all the activity of 
birds, hopping from bough to bough, on their hind limbs only. They watch the insects flitting among the leaves, 
listen to the fluttering of the moth as it darts through the air, lie in wait for it, and spring with the rapidity of an 
arrow, seldom missing their prize, which is caught by the hands. They make nests in the branches of trees, and 
cover a bed with grass and leaves for their little ones : are a favourite article of food in Senegal. A species larger 
than the others has lately been received alive, 0. Garnottii of Ogilby.] 
The Malmags {Tarsius ) — 
Have the tarsi elongated (fig. 6), and all the other details of form as in the preceding ; hut the interval 
between their molars and incisors is occupied by several shorter teeth [that is, their upper canines are 
very small ; and] the middle upper incisors are elongated, and re- 
semble canines. [There are but two permanent lower incisors, and the 
inferior canines present more of the ordinary form and direction.] Their 
muzzle is very short, and their eyes still larger than in any of the fore- 
going. [Tail very long, and almost naked.] Are also nocturnal ani- 
mals, and insectivorous ; inhabiting the Molluccas. 
[Two species are known, T. speetrum, Geof., {Lemur tarsius, Shaw ; T. fusco- 
manus, Fischer,) and the T. baneanus of Horsfleld. It is observed by Geoffroy 
that although the Malmags have the external ears much less developed than in 
the Galagos, this inferiority is counterbalanced by the far greater volume of the 
auditory bullae of the temporal bones, which are so developed as to touch 
each other; and thus the sense of hearing is, by another mode, rendered 
as acute in the former as in the latter. The Malmag has an aversion to light, 
and retires by day under the roots of trees ; feeds chiefly on lizards, and leaps 
about two feet at a spring ; is easily tamed, and capable of some attachment ; 
holds its prey in its fore-hands, while it rests on its haunches ; produces one 
young at a birth, and lives in pairs.] 
Travellers should search for certain animals figured by Commerson, 
Fi^. 6.-Foot of the Malmag. and which Geoffroy has engraved {Ann. Mm. xix. 10), under the name of 
Cheirogales {Cheirogaleus). 
These figures seem to announce a new genus or subgenus of Quadrumana. [Three species are re- 
presented in Commerson’s drawing, all of whieh appear to be now authenticated by specimens. Their 
proportions are those of the Galagos ; dentition as in the Malmags, except that they retain all their 
inferior incisors ; the head is round, the nose and muzzle short, lips furnished with whiskers, the eyes 
large and approximate, and the ears short and oval ; the nails of the four extremities are compressed 
and somewhat claw-like, and the tail is long, bushy, and regularly cylindrical. 
Three or more species are known, all from the great island of Madagascar. They constitute the division 
Lichanos of Gray. 
The singular genus Cheiromgs, also, from the same peculiar locality, which is arranged by the 
author among the Rodentia, would appear to have much better claim to he introduced here, and near
