a tinge of fulvous ; the whiskers are short, and arise from the sides o 

 the face ; these, together with a conspicuous beard on the chin, and the 

 throat, chest, and abdomen, are white ; a streak of black hair runs from 

 the face, below the ear, and loses itself on the top of the shoulder ; and 

 between this black line and the hairs of the head, a conspicuous streak of 

 white runs below the ear ; the general colour of the back and head is 

 reddish olive brown, the hairs being grey at the base, and then ringed 

 fulvous and black ; a band across the forehead, above the eyes, and a 

 band traversing the vertex, from ear to ear, are black ; on the limbs, a 

 grey tint prevails, deepening to dusky black on the hands and feet ; the 

 tail is of a dusky grey above, white beneath ; the hands are short.

Some degree of confusion exists, with respect to the present species, 

 created by Audebert, who, under the title of Ascagne, has figured a variety of 

 the Blanc-nez, distinguishedjby the prevalence of a violet tint on the naked 

 parts of the face. Audebert conferred this appellation (viz., Ascagne), on 

 a living specimen, the original of his figure and description, which was 

 kept, for a short time only (having been the property of a private indi- 

 vidual), in the menagerie at Paris. Latreille afterwards, in Sonnini's 

 edition of BufFon, gave a figure of the same animal, from a drawing by 

 Marechal, accompanied by a description founded on that of Audebert. 

 Cuvier subsequently published a new account of this identical Guenon, 

 with a much superior figure than that given by Latreille, but from the 

 same original drawing. A second living specimen has been beautifully 

 figured and described by Frederic Cuvier. Audebert pronounced it to be 

 specifically distinct from the Blanc-nez of Allamand ; so, again, though 

 not without some scruples, did Latreille. By Frederic Cuvier, it seems 

 to have been regarded as a variety ; but his brother, the Baron, deemed 

 it identical with the preceding Guenon, and, rejecting Audebert's pro- 

 posed denomination, described it under Allamand's term, as rendered by 

 BufFon, in his Supplement, of Blanc-nez. In the last edition of his 

 great work, however, he has adopted the name Ascagne for the species, 

 but without indicating the Blanc-nez of Allamand as a variety. Des- 

 moulins again notices the species under the appellation Ascagne, yet so 

 far differs from Cuvier, as to make it a variety of the Blanc-Nez. Erxleben, 

 Gmelin, GeofFroy, Desmarest, and Bennett, like Cuvier, appear to have 

 considered the Blanc-nez and Ascagne completely identical. 



GENERAL HISTORY. The present species, like the Hocheur, is 

 gentle, graceful, and intelligent ; perhaps, however, not without a mixture
