Show 1871.] DR. J. E. GRAY ON EUPLERES AND GALIDIA. 297 the adult animal originally described and figured. The hinder costal shield and the last vertebral one are small compared with the rest, and are about equal in size. The other adult specimen has an entirely different external appearance from the typical specimen, so much so that one would hardly believe that it belonged to the genus Rhinoclemmys, which is usually so uniformly coloured and generally so smooth. It is of a pale brownish yellow above and below, being only rather darker on the sutures between the marginal and dorsal shields, between the sternal shields and the marginal shields. The dorsal and marginal shields are deeply concentrically grooved, and marked with elevated ridges radiating from the angles of the areola ; the lower shields are similar, but not so uniformly grooved. When the dorsal shields are very closely examined they are found to be variegated with numerous dark-brown dots leaving indications of concentric rings ; and these spots are more abundant in the areola, which is marked with a distinct yellow streak or oblong spot surrounded by a dark edge. The two hinder costals are small, regular in their shape, and partly overlap the small irregular last vertebral shield. 5. Additional Notes on the Genera Eupleres and Galidia, and Note on Lemur ruber. B y Dr. J. E . G R A Y , F.R.S. [Received April 3,1871.] The British Museum has recently received some additional specimens of Mammalia from Madagascar, collected by Mr. Crossley, who was sent out for the purpose by M r . Ward of Halifax. Among the animals received is a skin, in a more perfect state, of Eupleres goudoti, and two skeletons of the same, which I hope to induce M r. Flower or some other osteologist to describe in detail. The skin shows that the acute nose of Eupleres has a distinct but narrow central groove, and that it must be referred to the family Viverridce, and will form, in the first section of that family with hairy soles to the feet, a peculiar tribe called Euplerina, characterized by the form of the skull. In the same collection are adults of Galidia elegans and G. concolor, which are easily distinguished by having a naked band extending on the sole of the hinder feet. The nose of this genus is rather produced beyond the teeth, and has a distinct groove beneath. The claws of Galidia and Eupleres are arched, compressed, and acute, and partly retractile, but are evidently always raised from the ground, so as to be kept in this acute state. In the collection there was also a series of specimens of Varecia rubra, Gray, Cat. Monkeys & Lemurs British Museum, p. 71. All the specimens had the head, the tail, and the fore feet, and the underside of the body and four legs, intense uniform black, the back of the neck and a spot on the upperside at the base of the tail pure |
