acute ; the tail regularly ringed with scales, from between which 

 only a few scattered hairs make their appearance. The fur of the 

 upper surface is of a light grey at the base j but the longer hairs 

 have a blackish shade, with an intermixture of testaceous brown, 

 which is more obvious posteriorly and towards the lower part of the 

 sides. The flattened spines, which are numerous, are white and 

 transparent throughout the greater part of their length, with a dark 

 margin and blackish acuminate tip, beneath which they exhibit, ia 

 certain lights, somewhat of a changeable gloss. The moustaches 

 are few in number, black at the base and white at the tips, and reach 

 beyond the ears, which are naked, rounded with a slight point, ex- 

 tremely open, membranaceous, and of a dusky black. The whole 

 under surface, together with the insides of the limbs, the upper sur- 

 face of the feet, and the claws, are of a yellowish or dirty white. 

 The tail is of a uniform livid grey, but little darker above than 

 beneath, and tapering to a very fine point. 



Several imperfect skins of Mammalia, recently obtained by Mr. 

 Gould from Algoa Bay, were exhibited ; and Mr. Bennett remarked, 

 that notwithstanding their deficiency in the most important particu- 

 lars, they were yet of sufficient interest to claim the attention of the 

 Committee, on account of the extreme rarity of two of the species 

 to which they belonged, and of the probability that a third was alto- 

 gether unknown to science. 



One of them, the skin of a Monkey deficient as to head and hands, 

 was, Mr. Bennett stated, evidently referable to the Colobus polyco- 

 mus, Illig. ; the long milk-white tail, strongly contrasting with the 

 bright deep black fur of the body, being fully sufficient to charac- 

 terize it. On the upper part of the skin, above the shoulders, some 

 nearly white hairs were intermingled with the black ones. The only 

 discrepancy observable between the specimen and the description 

 of the species given by Pennant, was in the great length of the hairs 

 of the body, the greater number of them being four or five inches 

 long : this, it was remarked, might be dependent on age or locality. 



Another skin, equally imperfect with the preceding, was that of 

 the Colobus Jerrugineus, Illig., with the state of which, described by 

 M. Kuhl under the name of Col. Temminckii, the specimen agreed 

 in every respect except in the absence of any yellow tinge in the 

 rufous fur covering the under surface of the body. 



The third skin was still more imperfect than the others, having 

 attached to it no portion of the neck, extremities, or tail, and con- 

 sisting only of that of the body. Its length is 2 feet, its width 1^. 

 The dorsal portion is of a bright rufous fawn, which is continued on 

 the shoulders and on the buttocks, but from which the red nearly 

 disappears on the under surface, that being pale fawn. Across the 

 whole of the back, commencing between the shoulders and passing 

 backwards, a series of broad transverse glossy black stripes are seen, 

 which run down the sides, becoming narrower towards the belly. 

 These stripes are twelve in number, and are preceded and succeeded 

 by a few similar, closer set, and fainter stripes, of a deeper rufous
