Show 1871.] MR. P. L. SCLATER ON ANIMALS IN THE MENAGERIE. 223 (H. N. d. Mamm. pl. 45). When we received a second example in 1866 (Feb. 21), Dr. Gray described and figured it as a new species under the name M. inornatus (P. Z. S. 1866, p. 202, pl. xix.). But I see no reason to change m y former determination. The figure in the 'Histoire Naturelle des Mammiferes,' although stated to have been taken from a drawing*, agrees in nearly every respect with our specimen. In August last Mr. W . Jamrach deposited in the Society's Gardens three Monkeys of this species, along with two of M. ocreatus and six of the so-called Cynopithecus niger. O n the 1 st of January of the present year we purchased two of these animals, which are still living in the Gardens. It is unfortunate that we do not yet with certainty know the exact locality of this Macaque. But I think it is probably Borneo, as already conjectured by Dr. Gray. This Macaque is of exactly the same form as M. ocreatus (figured P.Z.S. 1860, M a m m . pl. lxxxii.) ; and the young animals of the two species are so much alike, that one of Mr. Jamrach's specimens, supposed when it was deposited to be M. maurus, has since turned out to be M. ocreatus. 4. ATELES GRISESCENS, Gray, P.Z.S. 1865, p. 732; Cat. of Monkeys, p. 42. Dr. Gray founded this species of Ateles upon a specimen that was living in our Gardens in 1864. It was brought home by Mr. E. Greey, F.Z.S. (who was at that time an officer in the West-Indian Mail Company's-Steam-ship 'Shannon'), on the 29th Oct., 1864. Referring to Mr. Greey's letters, I regret to find that he did not know the exact locality of it, but only states that it was obtained by him at St. Thomas's, and had already been three years in captivity, so that it was quite adult. In 1869 (Oct. 12) we purchased of a London dealer a somewhat similar specimen, which died twenty-six days afterwards. It was a young half-grown male. I have compared its skin (which I now exhibit) with the typical specimen of A. grisescens, now in the British Museum, and believe them to be probably identical. The young animal is, as might be expected, rather lighter in colour, particularly below, but above exhibits the same mixture of black and greyish hairs as in the original. The tail is nearly black above, with a light line of greyish hairs below. The length of the body is 14 inches, of the tail 1 6 inches. There is no rudiment of a thumb apparent. It is possible this may be a good species, and still turn up in some part of the Central American or the Columbian coast, whence Mr. Greey's specimen probably came ; but I do not yet consider it sufficiently well established. 5.
