gascar, and the qxiadrumana are only represented by 

 the lemurs, of which there are six genera and thirty 

 three species ; first half the whole number are the 

 mammals of the island. The " lemurs " are spread from 

 Angola and Guinea to the malayan Archipelago, but 

 Madagascar is the great head quarter of the family 

 and of the four sub families two are exclusively con- 

 fined to the Island. The Gheiromys or aye-aye, is a very 

 peculiar type, intermediate in habit between a monkey 

 and a squirrel, with very large ears, large eyes, long 

 claws, and a long bushy tail. It is now classed at the 

 end of the quadrumana, and is quite confined to 

 Madagascar. There are six batg but they all belong 

 to widely spread families. Of the insectivorous ferae 

 there are about a dozen consisting of one shrew, a 

 large cosmopolitan groups ; and all the rest centetidoe 

 a group allied to the hedgehogs and moles only known 

 elsewhere at the present day in two or three of the 

 larger West Indian Islands. In carnivora, the lions, 

 bears, tigers, leopards and hyenas of the adjacent 

 continent are totally absent, and the family is repre- 

 sented only by cryptoprocta ferox, a cat-like planti- 

 grade animal of savage disposition, like small leopard 

 in the shape and size, which is confered to the Island, 

 and has no near affinity ; several civets and ichneumon. 

 The rodentia consists of four species of rats and mice 

 of peculiar genera, which as individuals, are numerous 

 and troublesome. In ungulata the antelopes so 

 plentiful both in Asia and Africa, the buffalo, horse,
