ON TPIE LEMURID-E: OR, 
5. — Black-fronted Lemur (hemur nigrifrons, Geoff.) —M. Geoffroy considers 
this species to be identical with an animal termed by Petiver Simia 
sciurus. —In Mus. Zool. Soc* 
0. —White-fronted Lemur (Lemur albifrons^ Geoff.)— First described by M. 
Geoffroy St. Hilaire, and afterwards figured by Audebert, in his His- 
toire Naturelle des Singes et des Makis. —In Mus. Zool. Soc. 
7. —White-handed Lemur (Lemur albimanus^ Geoff.) —Described first by M. 
Geoffroy, and figured by Audebert.— In Mus. Zool. Soc. 
8. —Mongooz Lemur (Lemur mongos, Linn.) —First described as the Mongous, 
by Edwards, in his Gleanings. In Mus. Zool. Soc. 
9. —Brown Lemur (Lemur fulvus, Geoff.) —Grand Mongous, Buffon, Supp^ 
7, p. 118, fig. 133. 
10. — Anjouan Lemur (Lemur Anjuanensis, Geoff.)—F rom the island of An- 
jouan, near the coast of Madagascar.—Much doubt exists as to the genuine¬ 
ness of this species. F. Cuvier regards it as the female of the White-fronted 
Lemur.—We have never seen a specimen. 
11. —Collared Lemur (Lemur collaris, Geoff.) —First described by Geoffroy 
St. Hilaire. —In Mus. Zool. Soc. 
12. —Bing-tailed Lemur (Lemur Catta, Linn.)— In Mus. Zool. Soc. Mococo 
of Buffon. 
13. —Rufous Lemur (Lemur rufus, Audeb.) —Golden red above, pale yellow 
beneath; circumference of the head white; a longitudinal stripe of black 
from the occiput to the muzzle. Maki roux of Audebert, with a figure. 
Leaving the genus Lemur, as restricted by modern naturalists, Indris of 
Lacepede (Lichanotus, Illig.), presents itself, as in close alliance with that 
which we have just left. Agreeing with Lemur in all its essential characters, 
the genus Indris is distinguished by a difference in the details of the dental formula, 
the incisors being four above and four below; molars four above on each side, and 
five below. The hinder limbs are extremely long; the head is broad, the muzzle 
short, and the hands are long. To this it may be added, that the tail is reduced 
to a mere tubercle; such, at least, is the case in the only genuine species of this 
form with which we are acquainted, viz., the Indri (Indris brevicaudatus, 
Geoff. ; Lemur Indri, Linn.) It is true that a second species, the Long-tailed 
Indri (Maki bourre of Sonnerat ; Maki fauve, Buff. ; Lemur laniger, Gmel. ; 
and Indris Longicaudatus, Geoff :) is described in addition to the preceding, 
but only, as it would seem, on the authority of Sonnerat. Cuvier, in the last 
edition of his Regne Animal, does not admit it in the genus Indris, observing 
that it has need of revision; as it respects ourselves, we are inclined to consider it 
as identical with an animal described in the Zoological Proceedings, as Propitke^ 
cus diadema, Benn., or at least as an immediate ally. We cannot, liWever, help
