of this species, and at Lungkeaou (S. W. Formosa) one of an appa- 
rently younger specimen. They all show smaller heads than in 
Wolf’s figure (P. Z. S. 1862, p. 347). All these skins have short 
tails, that of the Lungkeaou specimen not being ripped open; so 
that there can be no doubt of the distinctness of the species in that 
character from the Z. macrocelis. This Lungkeaou specimen is 
lighter than those from Sawo in the tawny hue of its upper parts, 
and its pale under parts are nearly white; the streaks on its back 
are not so broad, and do not so frequently coalesce ; its face is more 
narrowly and distinctly streaked, and its tail is more narrowly and 
numerously banded. The ears of all are black behind, with a light 
spot low down. Their moustache-bristles are some black and some 
white. The Lungkeaou skin is the only one that has legs. The 
feet appear to have been small, and the spots on the sides of the legs 
small and distinct.

** Paguma larvata.—I have received further specimens. The ears 
were in all small and round, as I described them; but the tail varies 
in length, and in the greater and less amount of black along its length. 
«* Vespertilionide.—Most of the Bats that fly about of an evening 
are small, and, I think, of the same species as those procured at Tai- 
wanfoo. I have, however, a couple of. specimens of a small Leaf- 
nose, taken in the cave at Kelung, which will be interesting. The 
other day I observed a species (of Pteropus?) of a bright colour, 
about 8 inches long, hanging by the heels on a large leaf. I, unfor- 
tunately, had no gun with me, and, trying to knock him down with 
my stick, missed him. The Chinese are very unsuccessful collectors 
of Bats, and very rarely bring me examples. 
“* Porcula taivana.—I have not managed to procure or get a sight 
of an adult. The largest I have seen was perhaps half-grown, in 
which the stripes and spots still remained. The natives insist that 
the animal is so marked all its life. I have purchased several young 
ones, with the view of sending them to the Society, but have not 
succeeded in inducing them to live. One lived with me for over a 
month. I took it to Foochow with the hope of getting it off all 
safe, but it died the day after my arrival at that place. A half- 
grown Pig of this species was bought by a friend here. It was very 
wild, and always jumped furiously at any person that came near its 
pen. It was covered with rather long bristles, longest down the 
back, and had a white tail. I despair, for the present, of getting a 
specimen in this vicinity ; but I may meet with it again in the south. 
I will now enumerate the additions that I have made to my first list 
of eighteen species of Mammals of Formosa (P. Z. 8. 1862, p. 347).

the island.
