Show 874 MR. G. E. DOBSON ON RECENT ADDITIONS TO THE [Nov. 5, be conveniently arranged for description and remarks under the heads of the four zoological regions thus represented. 1. Australian Begion. PTEROPUS GERMAINI, n. sp. Ears shorter than the muzzle, concealed by the long fur of the head, triangular, obtusely pointed, thinly clothed throughout with soft hairs. Fur long and woolly, like that of Pt. aneiteanus ; on the back long like that of the head, directed backwards. Humerus and forearm rather thinly covered with straight fur, like that of the back. The legs are clothed with long fur which extends to the backs of the feet; the margin of the wing membrane above, almost as far outwards as the extremity of the fifth finger, is clothed with straight appressed hairs ; the posterior margin of the narrow interfemoral membrane is quite concealed. Face in front of and immediately above the eyes light greyish brown; head and the whole inferior surface of the body dark blackish brown, interspersed with several shining greyish hairs, the shoulders and back darker, the rump and legs greyer; upper surface of the neck and shoulders pale yellow, with reddish extremities. Teeth simple, like those of Pt. medius; the first upper premolar small, scarcely raised above the level of the gum, and occupying the centre of the small space between the canine and second premolar ; last upper molar slightly larger than the first lower premolar, and about the size of the last lower molar. Length (of a not quite adult $ ) , head and body about 6" ; head 2"*3 ; ear 0"*8 ; forearm 4"*7 ; thumb 2"*3 ; third finger- metacarp. 3", 1st ph. 2"-5, 2nd ph. 3"*5 ; fifth finger-metacarp. 3", 1st ph. 1"*5, 2nd ph. 1"*35; tibia 2"*2 ; foot 1"*7. Hab. New Caledonia. This species resembles externally, to some extent, Pt. aneiteanus ; but the very different form of the teeth at once distinguishes it. From Pt. vetulus, inhabiting the same islands, it is distinguished by the completely different colour of the fur, as well as by the absence of transverse basal ridges in the molars and premolars. The food of this species appears to consist, in part at least, of figs, as I found portions of these fruits in the mouth of the typical specimen. At the request of M . Milne-Edwards, who pointed out to me this new species, I have much pleasure in connecting with it the name of its discoverer, M . Germain. PTEROPUS VETULUS, Jouan. Besides the type, the Museum possesses several specimens of this species, both male and female, from New Caledonia. These all more or less resemble the type specimen in the colour aud distribution of the fur ; and the few differences observable are unimportant. Hab. New Caledonia ; Loyalty Isles. |
