THE WHITE-HEADED MONGOOS.

Lemur Albifrons. Geoff.

Belonging to a different tribe of the same grand division with the true Monkeys, from which they are more readily distinguished¹ by their general form and habit than by any very remarkable² deviation³ in their structure or organization, these agile⁴ and playful little creatures form a group which naturally follows in immediate⁵ succession. The technical peculiarities⁶ on which their separation from the Monkeys is founded are usually deduced from their teeth and nails; but other and more obvious characteristics are afforded by the form of their heads, of their tails, and of their hinder extremities⁷, and these assist in confirming a distinction which might[152] otherwise be regarded as arbitrary and unnecessary. The teeth of the Lemurs are, like those of man and of the Monkeys of the Old World, thirty-two in number, and consist of four incisors, two canines⁸, and ten molars in the upper jaw⁹, and of six incisors, two canines, and eight molars in the lower. Such at least is the usual statement with respect to their dentition; but M. Geoffroy maintains, on the other hand, that the number of incisors is equal in both jaws¹⁰, and coincides with that of the Monkeys; the two outermost¹¹ of the six, which are larger than the rest, being in his opinion the true canines; while the canines, commonly so called, are in fact only the first of the series of molars. This conjecture¹² unquestionably derives¹³ considerable strength from the fact that, when the animal closes its mouth, the supposed canines of the lower jaw pass behind those of the upper, a position directly contrary to that which they uniformly assume in every other animal that is furnished with that kind of teeth. On each of their four hands they have four fingers of moderate length, and a thumb which is capable of being opposed to them almost equally well with that of the other Quadrumana; they are consequently enabled to grasp whatever they seize with the greatest precision. The peculiarity¹⁴ of their nails consists in the shape of that of the index of the hinder hands, which forms an elongated¹⁵, curved, and pointed¹⁶ claw, approaching in some degree to those of the carnivorous quadrupeds. All the rest of their nails are broad and flat like those of the Monkeys. Their posterior extremities are longer than their anterior¹⁷; and their body and limbs are light, graceful¹⁸, and well proportioned. The tail, which is of uniform thickness[153] throughout, is longer than the body, and, in common with it, is clothed with long, soft, and woolly hair. The head is long, triangular¹⁹, and gradually tapering²⁰ into a slender and pointed muzzle²¹, which, in proportionate length, far exceeds that of any of the Monkeys; the ears are short and rounded; and the whiskers but little developed.

The whole of the genus thus characterized are natives of Madagascar and of two or three of the smaller islands in its immediate vicinity. They appear to occupy in that remarkable and very imperfectly known country the place of the Monkeys, none of which have yet been detected within its precincts. They are said to live in numerous troops upon the trees, and to feed upon fruits and insects; but their habits in a state of nature have not yet been observed with sufficient accuracy to enable us to form any clear idea of their mode of existence. In captivity²² they are particularly tame and good tempered, fond of being noticed, delighting in motion, and climbing and leaping with surprising agility²³. They are, however, in some degree nocturnal; and when undisturbed pass a considerable portion of the day in sleep. If alone, they roll themselves up in the form of a ball, and wind their long tail in a very curious manner round their body, apparently²⁴ for the purpose of keeping themselves warm; for they are naturally chilly²⁵, and delight in basking²⁶ in the rays of the sun, or in creeping as close as possible to the fire. When two of them are confined together, they interlace their limbs and tails after a singular fashion, and placing their heads in such a position as that each may, if disturbed, see what is going on behind the other’s back, fall comfortably asleep.

The species to which the beautiful pair in the Menagerie belong has all the habits of its group. It is characterized by the clear fulvous brown colour of the upper surface of the body and outer side of the limbs, gradually becoming lighter²⁷ on the under and inner surfaces, and deepening in its shade towards the tail, the greater part of which is nearly black. The muzzle and the hands are bluish black. The male has the whole of the forehead, the sides of the cheeks, and the under part of the lower lip covered with a white fur, which in the female is of a blackish gray and much less developed; her general colour is also of a lighter tinge²⁸. This remarkable difference would lead us to question the specific identity of the two animals, were we not assured by M. F. Cuvier that he had verified the fact by what is usually regarded as an unequivocal test. Mr. M’Leay has, however, thrown considerable doubt upon the accuracy of the inference thus attempted to be drawn²⁹, by exhibiting to the Linnean Society a female, in whom the white fur of the head was as distinctly developed as in her male companion. The whole of the species of this group require, in fact, an accurate revision.
