RARE MONKEY.

plainant. It appeared that some feiticeira had sprinkled 
a quantity of the acrid juice of a large arum on her 
linen as it was hanging out to dry, and it was thought 
this had caused a serious eruption under which the lady 
suffered. 
I seldom met with any of the larger animals in these 
excursions. We never saw a mammal of any kind on 
the campos ; but tracks of three species were seen occa- 
sionally besides those of the J aguar : these belonged to 
a small tiger cat, a deer, and an opossum ; all of which 
animals must have been very rare, and probably nocturnal 
in their habits, with the exception of the deer. I saw in 
the woods, on one occasion, a small flock of monkeys, and 
once had an opportunity of watching the movements of 
a sloth. The monkeys belonged to a very pretty and 
rare species, a kind of marmoset, I think the Hapale 
humeralifer described by Geoffrey St. Hilaire. I did 
not succeed in obtaining a specimen, but saw a living- 
example afterwards in the possession of a shopkeeper at 
Santarem. It seems to occur nowhere else except in 
the dry woods bordering the campos in the interior 
parts of Brazil. The colours of its fur are beautifully 
varied ; the fore part of the body is white, with the 
hands gray ; the hind part black, with the rump and
