I subsequently received a live adult, which I kept for some time 
in a cage, feeding it on bread and fruits. It was exceedingly fierce, 
darting at the hand that was thrust towards it, crouching in a corner 
and glaring savagely at the intruder. It uttered sharp and angry 
cries. In the dark its pupils, which were round, and not linear, 
emitted a hollow, greenish light, proving the animal to be nocturnal 
in its habits. 
12. ScluROPTERUS KALE®NSIS, D. sp. 
This is one of the smaller group of Scivropteri, with flat diverg- 
ing tails. I have, unfortunately, only a pair of immature specimens, 
which I purchased from a savage who was fondling them in his 
bosom, and tried to keep alive without success. Young as my 
specimens are, they are much larger than the diminutive representa- 
tive of this speciesin Japan. This species is most nearly connected, 
in the style and mottled appearance of its fur, with the Seiwropterus 
albo-niger of Nepal, but differs in colour. The Javan species (S. 
horsfieldii) differs from it in having a woollier fur, without any mot- 
tling. In ours the tail is about two-thirds of the length of the body ; I 
should say, therefore, that the mature animal would be about 16 inches 
long. Entire upper parts reddish buff, mottled with deep brown ; 
under parts pale buff, rosy on the flanks and under the legs. Teeth 
white. 
Three species of Flying Squirrels are mentioned in the ‘ Fauna 
Japonica,’ two as occurring in Japan—Pteromys leucogenys and 
P. momoga. The latter, it is said, is intermediate in form between 
the genus Pteromys and Sciuropterus, and we should therefore take it 
to be more nearly allied to our species S. Aaleénsis ; but on reading 
ing Temminck’s description, I find that the fur is mentioned as 
woolly. In ours it is silky, more as represented in his P. setosus, 
a very different species, however, from the Indian Archipelago. 
Of the habits of our species I know nothing. 
13. Lupus sinensis. Chinese, Swan-taw (Hill-Rabbit). 
The Hare found in the champaign as well as hilly country of 
both South-west and North-west Formosa is identical in species with 
that distributed throughout China, from Canton to Peking. I find in 
the Chinese as also in the Formosan animals, that the tints vary some- 
what, and that in some the black on the cheeks and behind the ears 
is almost entirely wanting. The Formosan specimens are somewhat 
more brightly coloured, and the rufous on the hind neck is’ livelier ; 
whereas the North China Hares are greyer, especially in winter, and 
more distinctly marked with black. I have two small Leverets from 
South Formosa: these are of a strong olive hue, densely sprinkled 
with black hairs. These Hares, both in China and Formosa, retire 
to the hills in summer to breed, and return again to the plains in 
winter. They seek shelter in the holes of rocks or grave-mounds, 
and in these rear their young. They are said to burrow ; but this I am
