SECTION X. CERDOCYON. 
THE AGUARA FOXES. 
WE pass from the subdiurnal Aguara Dogs, by an 
almost insensible degree, to the Aguara Foxes, whose 
structure is more completely vulpine, having tails 
with brushes even larger and longer than those of 
true foxes. They are equally low on the legs, 
equally supple, with a fur nearly as abundant, and 
kept very clean, with colours forming mixtures of 
grey, buff, white, and black, the tip of the tail 
always black; but their eyes do not appear to 
assume the vertical contraction with equal facility 
or perfection, and they are thence more crepuscular 
than nocturnal, prowling only in moonlight nights, 
and keeping abroad till the sun becomes hot. They 
can be domesticated, and it is believed will form 
cross breeds with the Dusicyon and Canis fami- 
liaris.
