Semnopithecus cruciger : in a notice of three specimens by Thomas, P. Zool. 
Soc. London, 1893, p. 3, it is suggested that this form may prove to be 
merely an erythrism of S. chrysomelas. 
Semnopithecus sabanus, n. sp., Thomas, Ann. Nat. Hist. (6) xii, p. 230, 
N. Borneo. 
Cercopithecus moloneyi , n. sp., Sclater, P. Zool. Soc. London, p. 252, 
pi. xvii, British Central Africa. In the same paper the author figures 
C. schmidli (pi. xvi), and gives a synopsis of the genus. Excluding 
Myopithecus , the author recognizes from personal observation 31 
species, divided into several groups, in addition to which there are 
15 which have not come under his notice. In a supplemental paper 
(op. cit. p. 441), descriptions and figures are given of C. houiourlinii 
and C. brazzce (pi. xxxiii). Matschie, SB. Ges. naturf. Berlin, 1893, 
p. 212, comments on this list, and gives a diagnosis of several of the 
species.
