This Fox is common on the bare granitic hills of Amoy ; and I 
have seen as many as six together at a time. When pursued they 
spring with great agility from rock to rock, and soon outrun a Grey- 
hound on such rough ground; but on the plains they are no match 
for the dog. They descend to the plains at night, and rob the hen- 
roosts. I have also seen them in Hongkong island. About Tient- 
sin, in North China, Foxes are also common; but I have never 
handled a specimen from any northern locality. No Fox has been 
found in Formosa.

fox.) 
Two Foxes were brought to me at Amoy in 1867, from the higher 
mountains of Fokien. They are very like the Black-bellied Fox of 
Europe, V. vulgaris, var. melanogaster, Bp.; but are remarkable 
for having a fine line of chestnut on each side of the belly. They 
are very brightly coloured, and so differ conspicuously from the last- 
described pale species, though in form and size very similar. Un- 
fortunately the skulls were not saved. 
Head grizzled with white and chestnut, round and under eye rich 
chestnut. A broad angular mark of brown from anterior corner of
