but no sign as yet of the rufous tail-tip. Upon the whole, the 

 very large fine specimen under consideration does not differ more 

 from ordinary domesticated examples of the pig-tailed monkey, 

 than does an unusually fine wild old male of the M. Rhesus which 

 I procured some time ago in this vicinity, from such domesticated 

 specimens of the latter as must be familiar to the observation of 

 most naturalists who are conversant with the study of mammalia. 

 Capt. Phayre obtained these animals in a mountainous and rocky 

 situation, and it is doubtless Dr. Helfer^s second species of (so- 

 called) Cercopithecus. It belongs indeed (as does also M. Rhesus) 

 to the division Papio of Mr. Ogilby, which comprehends all the 

 short-tailed Macaci of Cuvier ; but not, as I suspect, to the Papio 

 of Prof. Owen*, which I have reason to believe applies to the 

 long-tailed African Baboons, or the Cynocephali, Auctorum, ex* 

 elusive of C. Mormon and leucophceus, or the mandrill and drill : 

 whereas the long-tailed Macaci, such as the next species, together 

 with M. radiatus and M. sinicus of S. India, are referred by Mr. 

 Ogilby to Cercopithecus. But the truth is, that if we once com^ 

 mence dividing the group Macacus, as now generally recognised, 

 nearly every species of it might be selected as a subgeneric type 

 per se, presenting various peculiarities of its own [e. g. M. niger, 

 nemestrinus, Silenus, Rhesus, cynomolgus, radiatus with sinicus, and 

 perhaps others with which I am less familiar) : and I certainly 

 much prefer the currently adopted system of restricting Cercopi^ 

 thecus to the numerous African species which want the fifth tu^ 

 bercle to the last inferior molar, and follow Mr. Martin in ap- 

 priating the name Cercocebus to those other long-tailed African 

 species which are known as the Mangabeys, or white-eyelid 

 monkeys, of which three have now been ascertained,— an arrange- 

 ment which has the advantage of according with the geographical 

 distribution of these animals, and by which, too, any of them 

 may be classified at a glance at their exterior by those who are 

 familiar with the subject f. 



M. cynomolgus (?). — Though possessing living examples of 

 both the M. nemestrinus and M. cynomolgus, I have found great 

 difiiculty in determining the skins sent by Capt. Phayre, which 

 I refer to these species, in consequence of the mode of prepara^ 

 tion of them, the skulls having been taken out and the faces irre- 

 parably injured ; but after full consideration I feel confident that 

 the present one is correctly assigned, if not the other also. A 

 pair of skulls of this are sent, from which the following dimen- 

 sions are taken. That of an adult male measures four inches and

f If I mistake not, the tail is in Cercopithecus and Cercocebus of con- 

 stant proportional length, being much longer than in any Macacus,
