POPULAR SCIENCE REVIEW. 
The last group of American monkeys comprises the 
delicate little Marmosets, or Ouistitis (Hapale), which differ 
notably from all the other apes, whether of the Old or New 
World ; so that some authors have purposed to raise them to the 
rank of a distinct family. Passing now to the second sub- 
order of the Primates, i.e. to the Lemuroids, or Half- Apes, we 
find a geographical distribution of much interest. 
The great bulk of the sub-order is exclusively confined to 
the Island of Madagascar, three genera only being found on 
the continent of Africa, and not elsewhere, and three others 
in South Eastern Asia only. In fact, the Lemuroids have a

distribution on the earth’s surface similar to that of the 
woolly-haired races of men. 
All the Half- Apes differ strikingly from the apes in 
external appearance, but there is much difference between the 
different kinds. 
The typical Lemuroids, the true Lemurs {Lermjbr\ are 
creatures with woolly fur, long tails, and pointed, fox-like 
muzzles. The allied genera, Hapalemur, Cheirogaleus, and 
Lepilemur, have snouts somewhat less elongated. 
The genus Indris contains the largest forms of the sub- 
order. There is a short-tailed Indri, and there are long-tailed 
forms. All the Lemuroids above noticed are Madagascar 
forms. 
There is a curious group of slow-paced, tailless, or short- 
tailed Lemuroids {Nycticebince)^ which contains two African
