able resemblance to the common Barbary species (Papio sylvanus) both 

 in general colour and in physiognomy, but differs materially in the 

 blackish brown shade which covers all the upper parts of the head, 

 neck, shoulders, and back. The face and ears are of a pale flesh colour, 

 not unlike the shade which distinguishes extreme age in the human 

 species ; the naked part of the paws is dirty brown, and the temples are 

 slightly tinged with a shade of scarlet, which the keeper informs me 

 spreads and deepens when the animal is feeding. The tail is about an 

 inch long, very slender, and perfectly naked ; but whether the last cir- 

 cumstance be not accidental I shall not take on me to say ; it appears, 

 however, to be the natural condition of the organ. The general colour of 

 the sides, under parts of the body, and extremities, is that pale olive brown 

 so common among other species of this genus, such as the Bhunder 

 (P. Rhesus), the Maimon (P. Nemestrinus), &c, and the hairs are equally 

 without annulations. The individual has all the liveliness, good-nature, 

 and grimace of the young Magot (P. Inuus and Sylvanus) ; but, like that 

 species, it will probably become morose and saturnine as it advances in 

 age and physical development ; qualities which, indeed, are common to 

 all the Papios, and pre-eminently distinguish them from the Cercopi- 

 thecs, Colobs, and Semnopithecs.
