The Sajouins form the third group; but as the name merely signifies those monkeys that have not the power of suspending themselves by the tail, it can hardly be considered a natural group, since there are very varied and numerous genera who lack this power. The group of Sajouins must therefore be subdivided into several lesser groups.
First of all we have the true Sajouins; and of these the Saimiri or Titi is the most distinguished species. This pretty little creature is about equal in size to a squirrel, and possesses all the playful disposition of the latter. Its childlike innocence of countenance, as well as its pleasing and graceful manners, render it a favourite pet wherever it can be obtained. Its rich robe of yellowish-grey, mixed with green, adds to the attraction of its presence. There are several species of Sajouins, known as the Widow monkey, the Moloch, the Mitred monkey, and the Black-handed Sajouin—all of them dwellers in the tropical regions of America. The Doroucouli is another small species, that in the nocturnal forest often alarms the traveller by its singular cry; and an allied species of Doroucouli constitutes, with the one above-mentioned, a second genus of the Sajouins.
The Sakis form of themselves another and somewhat extensive family of the Sajouins. There are a dozen species of them in all; and they possess the peculiarity of being insect-eaters. They are fond of honey, too; and are often seen ranging the woods, in little troops of ten or twelve, in search of the nests of the wild bees, which they plunder of their luscious stores.
The Ouistitis also constitute a genus. These, like the Saimiris, are beautiful little creatures—many of the species not being larger than squirrels, and marked with the most lively colours: as bright red and orange. There are many different kinds of small squirrels known by this name, or by its abbreviation—Titi—some of them belonging to the group of Saimiris, and others to the Ouistitis, properly so called.
Last of all come the little Tamunus; some of which, in beauty of colours, in playfulness of disposition, and other amiable qualities, need not yield either to the Saimiris or Ouistitis. They are equally prized as pets; and among their Creole owners have equally applied to them the endearing appellation of Titi-titi.
