The general colour of this species is brown, with a warmer tinge upon the sides, and round the face is a ruff of long, loose white hair, that gives the creature an aspect not at all unlike that of a pantaloon in a Christmas pantomime. I may mention that by many zoologists the White-fronted Lemur is thought to be only the female of the Black-fronted Lemur (Lemur nigrifrons).

In a corresponding cage is a specimen of the White-whiskered Lemur (Lemur leucomystax).

This animal has lived in the collection for nearly two years, and is quite tame and gentle. It is rather larger than the preceding species, and is a very pretty creature. The fur is long, soft, and of a reddish-brown colour upon the body, taking a black hue on the top of the head. Instead of the ruff of white hair that surrounds the head of the preceding species, there is a pointed tuft of white hair projecting from each cheek, just like the whiskers of an old man.

It is fond of being caressed, and, when no one takes notice, it attempts to call their attention by uttering a short grunt, frequently repeated, and sometimes gives vent to its impatience by a rather loud and deep barking sound. The observer should be careful to examine the eyes of the Lemur, their peculiar lustre having at times almost a startling effect, their depths seeming to be lighted up with a silvery fire.

We now come to the last of the monkey tribe.

Just now the Zoological Society is rich in treasures, possessing some of the rarest birds and quadrupeds at present known to science. The hippopotamus, for example, though not scarce in its own country, is so difficult a subject for transmission, that we may congratulate ourselves on the two magnificent specimens in the Gardens. The giraffe, too, partakes of similar conditions, and is, therefore, most valuable. But perhaps the two most remarkable creatures at present in the Gardens are the apteryx, a bird which is undoubtedly on the road to extinction, and is notable for laying an egg that weighs one-fourth as much as the mother bird; and the Aye Aye (Cheiromys Madagascariensis).

The Aye-Aye.—[Page 269.]

This wonderful animal derives its name from the exclamations of surprise uttered by some natives of Madagascar when the creature was first shown to them. It is eminently nocturnal in its habits, and on account of its dark fur and quiet movements is not likely to attract observation. It was first discovered by Sonnerat, who kept a couple of specimens for some time, feeding them upon boiled rice. They fed themselves in a very curious manner, using the long slender fingers of the fore paws for the purpose of conveying the food to the mouth.

A single dead specimen was brought to France by the discoverer, and the stuffed skin placed in the splendid museum in Paris; and for many years this was the only specimen in Europe. The accounts of the habits of the animal were exceedingly meagre; nothing was known of its customs when in a state of freedom, and the only trustworthy information which could be obtained was that which described the colour of the fur.
