262 DR, J. E. GRAY ON NEW MAMMALIA. [Noyv. 25, 
its tail, which induces me to form for it a section or subgenus, which 
I propose to call Uronycteris. 
Cynopterus (URONYCTERIS) ALBIVENTER. 
Tail elongate, free, produced beyond the narrow, short, interfemoral 
membrane. Nostrils much produced, tubular, far apart at the base, 
and diverging outwardly. Fur brown-olive, with greyer base to the 
hairs. Face and throat only slightly hairy, grey. Sides of the neck 
and breast yellow-brown. Side of the body brown. Chest and 
middle of the belly white. Wings brown. 
Hab. Morty Island (4. R. Wallace). 
The length of the forearm-bone 2 inches ; length of the tail (dry) 
nearly # of an inch. 
The wing-bone, on the upper surface of the wing, of both speci- 
mens is marked with some irregular white spots. These may be 
only accidental, or even artificially produced in the process of pre- 
servation or by carriage, as the spots on the two sides of the same 
wings are more or less unlike, and those of the two specimens are 
dissimilar. 
Mr. Keilish, the furrier, has kindly sent to the British Museum 
for examination the skin of a Leopard which he has received from 
Japan. It is well tanned, and marked on the inner side with the 
red impressions of two Japanese seals. The skin at first sight seemed 
much like that of a fine-coloured Hunting Leopard, but it is at once 
distinguished from that animal by the comparatively shorter legs, by 
the larger size and brown centre of the black spots, and from all the 
varieties of the Leopard by the linear spots on the nape and the 
spots on the back not being formed of roses or groups of smaller 
spots. I propose to call it 
LEOPARDUS JAPONENSIS. (Pi. XXXIII.) 
Fur fulvons, paler beneath. Back and limbs ornamented with 
ovate or roundish unequal-sized black spots. The spots on the 
shoulders, back, and sides converted into a ring by a single central 
spot of the same colour as'the fur. Spots on the back and legs large, 
oblong, and transverse. Head with small, regularly disposed, black 
spots. Nape with four series of narrow elongated black spots (the 
outer ones sometimes confluent into lines), and with a series of large 
black spots on each side of the back of the neck. Chest with a series 
of larger spots, forming a kind of necklace. Tail elongate, very 
hairy, spotted, paler, and with four black rings at the tip. 
Hab. Japan. 
The skin in its tanned state is 4 feet 6 inches, and the tail 2 feet 
10 inches long. 
Mr. W. Fosbrooke has kindly presented to the British Museum 
a small and beautiful species of Boshbock, which was captured by 
John Dunn, Esq., in the Ungo-zy Forest, between the Umbrelans
