MARMOSET.—VJacchus Vulgaris. 
limbs are instinct with fiery activity, every sense is aroused to keen perception, and the 
creature sets off on its nightly quest. Such is then its agile address, that it can capture 
even the quick-sighted and ready-w inged flies as they flit by, striking rapid blows at 
them with its little paws. 
The general colour of the Douroucouli is a greyish-white, over which a silvery lustre 
plays in “certain lights. The spine is marked with a brown line, and the breast, abdomen, 
and inside of the limbs, are marked with a very light chestnut, almost amounting to 
orange. The face is remarkable for three very distinct. black lines, which radiate from 
each other, and which have earned for the animal the title of « Trivergatus,” or “ Three- 
striped.” There are but very slight external indications of ears, and in order to expose 
the organs of hearing, it is necessary to draw aside the fur of the head. On account of 
this peculiarity, Humboldt separated the Douroucouli from its neighbours, and formed it 
into a distinct family, which he named “ Adtes,” or “ Earless.” 
Guiana and Brazil are the countries where this curious little animal is found. 
Although by no means an uncommon species, it is not taken very plentifully, on account 
of its monogamous habits. The male and his mate may often be discovered sleeping 
snugly together in one bed, but never in greater numbers, unless there may be a little 
family at the time. Its ery is singularly loud, considering the small size of the animal 
which utters it, and bears some resemblance to the roar of the jaguar. Besides this 
deep-toned voice, it can hiss or spit like an anery cat, mew with something of a cat-lke 
intonation, and utter a guttural, short, and rapidly repeated bark. The fur is used for the 
purpose of covering pouches and similar articles. 
The beautifti little creature which is so well known by the name of the MARMOSET, 
or OUISTITI, is a native of the same country as the Douroucouli, and is even more attrac- 
tive in its manners and appearance. The fur is long and exquisitely soft, diversified with 
bold stripes of black upon a ground of white and reddish-yellow. The tail is long and 
full; its colour is white, encircled with numerous rings of a hue so deep that it may 
almost be called black. A radiating tuft of white hairs springs from each side of 
the face, and contrasts well with the jetty hue of the head. 
On account of the beauty of its fur, and the gentleness of its demeanour when rightly 
treated, it is frequently brought from its native land, and forced to lead a life of compelled 
civilization in foreign climes. It is peculiarly sensitive to cold, and always likes to have
