new or obscurely known species. 
IV. Some account of the Comparative Anatomy of two species of the 
genus Cercocebus, Geoffroy. By P. C. EYTON, Esq. 
I obtained the two monkeys from which the following notes were 
made, from Mr Wombwell, when his menagerie was at Shrews- 
bury, in January 1836 ; where they died while in his possession. 
The lungs of both, as well as some of the other viscera, were much 
diseased, the former adhering in both instances to the parietes. 
CERCOCEBUS SAB-EUS, Griffiths' Cuvier ; Simia sabsea, Linn. 
Green- Monkey, Penn. 
The description of this monkey, which was a male, corresponded 
precisely with that given in the synopsis of the Mammalia in Grif- 
fiths' translation of the " Regne Animal," and also with that in 
Sir William Jardine's Naturalist's Library. The measurements 
were as follow : Length from the tip of the nose to the root of the 
tail, 1 foot 5J in. ; length of the tail, 1 foot 4 in. ; length of the 
intestinal canal from the pylorus to the anus, 14 feet 4 in. ; length 
of the rectum, 3 feet 2 in. : length of the kidneys, 2 in., greatest 
diameter, 1 in. : liver five-lobed : diameter of the small intestine 
inflated, 1 in.; above the ccecum, f in.; diameter of the rectum, 
1 in. ; below the ccecum, 1^ in. ; length of the ccecum, from the 
NO. v. F f
