pears to be in the size of the head, which, instead of being one-fourth 
of the length of the body as in C. vulpes, approaches to one-third. 
The fore paws are much shorter than in the other species, whilst 
those behind are equal, thus making the respective difference of the 
fore -arm greater. The ears are shorter than in the C. vulpes ; 
and Professor Savi has noticed a peculiarity, which, if it be con- 
stant, is rather singular. The young of the C. vulpes, when first 
whelped, have the hair long and whitish, whilst in the new spe- 
cies it is short and of an ash-gray colour. We may add that, in 
our own opinion, the proportions and general appearance of the ani- 
mal are different ; the head being larger, and the tail very bushy, 
alter his port and bearing. The Roman fox in winter has the under 
parts of the belly, breast, tail, back of the ears, part of the paws, 
and under jaw, black, the other parts of the body being tawny. In 
summer the black parts change to white, thus inverting the general 
order of nature as we approach the north. On this winter colour 
the name has been founded ; but independently of the general ob- 
jection to the adoption of colour as a distinctive appellation, there 
are two very strong ones to using it in this instance ; the one, that 
it is by no means constant, the same individual varying in intensity 
of colour from one year to another, probably from age, or health, or 
diet, the other that in Nilson's Fauna Scandinavia, an individual of 
C. vulpes is figured which had precisely the colour of the C. me- 
lanogaster ; and within our observation we remember assisting 
at the death of a fox which had been maimed by a trap ; it had a 
quantity of black in different parts of the body, differing very 
much from the common appearance of its brethren. For these 
reasons we think the name had better have been selected from 
some of the points of organic difference, than from the fleeting 
and uncertain one of colour. The author considers that his species 
resembles the C. fulvus of Desmarest, an American fox, more near- 
ly than any other. The C. Niloticus of the French Institute, might 
be supposed to be identical, from the contiguity of regions, but the 
osteology of the head is different, in the latter species. 
The limits of the habitat of C. melanogaster are not yet exactly 
denned, but would appear to be those of the great southern zone of 
Europe, which comprises Italy south of the Apennines, Greece, the 
south of Spain, and the Islands of the Mediterranean. Like the 
peasantry in other places, the Romans consider that there are two 
species of the common fox, the one not eatable, the other, which is 
called, "Leprene," probably from its fancied resemblance to the 
flavour of the hare, being admitted to the table. Not having made 
the trial, we agree with the Prince, " de gustibus, " &c.
