is not uncommon in captivity ; we have had some 25 specimens o£ 

 it since 1860. 



19. Ceecopithecus albigulaeis. 



Seninopiiheais'i albogularis, Sykes, P. Z. S. 1831, p. 106. 



Cereopithecus albogularis, Sykes, P. Z. S. 1832, p. 18; Martin, 

 M. An. p. 512 ; Eraser, Zool Typ. pi. ii. (1848) ; Wagn. Saug. 

 Suppl. V. p. 45 (1855); Gray, P.Z.S. 1868, p. 182; id. Cat. 

 Monk. B. M. p. 24 (1870) ; Schleg. Mus. P.-B. vii. p. 79 (1876) ; 

 Scl. List Vert. (1883) p. 9 ; True, Pr.U.S. Nat. Mus. xv. p. 448 

 (Kilimanjaro). 



Hah. East Africa, Kilimanjaro (Abbott) : Gold Coast (Pel). 



Sykes's Monkey, as this species is commonly called, is also fre- 

 quently brought alive to this country. We have had some 25 

 specimens in the Menagerie during the past thirty years. 



It belongs to the Mona group, but has no white thigh-patches, 

 and the rump is more or less rufous. 



8chlegel gives the locality of this species as Gold Coast (Pel) ; 

 but it appears certainly to occur in East Africa, and it would be 

 desirable that specimens from these countries should be compared. 



20. Ceecopithecus campbelli. 



Cereopithecus campbelli, Waterh. P. Z. S, 1838, p. 61 ; Eraser, 

 Zool. Typ. pi. iii. (1848); Martin, M. An. p. 544; Wagn. Saug. 

 Suppl. V. p. 47 (1855) ; Gray, P. Z. S. 1868, p. 182 ; id. Cat. Monk. 

 B. M. p. 24 (1870) ; Schleg. Mus. P.-B. vii. p. 81 (1876) ; Scl. 

 List Vert. (1883) p. 11 ; Jent. Notes L. M. x. p. 9 (Liberia), 



Cereopithecus burnetti, Gray, Ann. N. H. x. p. 256 (1842). 



Hab. West Africa: Gold Coast (PcZ) ; Liberia (-S(t«t/f.), common. 



Campbell's Monkey is by no means so common in captivity as 

 the two preceding species. We have had, so far as our modern 

 registers go, only eight examples of it. 



It is easily distinguishable from C. albogularis by the black rump 

 and outer surface of the thighs. It has a frontal band like the 

 Mona, but tinged with rufous. 



21. Ceecopithecus samango. 



Cereopithecus samango, Sundev. Ofvers. K. Vet.-Akad. Forh. i. 

 p. 160 (1844) ; Wagn. Saug. v. p. 44 (1855) ; Peters, P. Z. S. 1865, 

 p. 400 (Angola) ; id. Eeise n. Moss., Saug. p. 4 (Inhambane) ; 

 Gray, P. Z. S. 1868, p. 182; id. Cat. Monk. B. M. p. 24 (1870) ; 

 Schleg. Mus. P.-B. vii. p. 79 (1876) ; Scl. P. Z. S. 1888, p. 564. 



Hab. Natal (Wahlbevg); Mozambique (Peters); Angola (Wel- 

 luitscJi). 



A single example of this scarce Monkey was acquired by the 

 Society in 1888 (see P. Z. S. I. s. c). It died June 4th, 1890. I 

 now exhibit its skin. 



Schlegel has united to this species C. labiatus, Geoffr., but I can 

 see no traces of the white lips in our specimen, and am doubtful 

 about the identification.
