Indri

Indri, the ſecond new genus, conſiſts at preſent but of two ſpecies, the Linnæan lemur indri and the laniger; the former of which is lemur brevicaudatus of Geoffroy [i.e., Étienne Geoffroy Saint-Hilaire]; and the latter indri longicaudatus of the ſame author.

The indris are distuinguished by having only thirty teeth. [...] The Indri (Indris laniger) is the largest known species of the lemurine Quadrumana, measuring when erect more than three feet in height, and is of very remarkable form. [...] The indris inhabit the forests of Madagascar. They are very gentle, and although not remarkable for intelligence, are trained by the natives (who call the indri, "the man of the woods"), to hunt, probably for birds.

The Indri (Indri indri; top left), the largest prosimian at up to three feet long (excluding tail) and 22 pounds, eats plant matter.

The indri inhabits coastal and montane rainforest from sea level to about 1,800 meters.

Indris are known for their calls, some of which are truly eerie and can be heard for miles in the dense undergrowth.
