1905.] MAMMALS OF SOUTHERN CAMEROON'S. 71 



I obtained a number of specimens of embryos taken from the 

 bodies of monkeys killed by natives. These were mostly brought 

 in May, June, and July, though some came also in October and 

 November. 



Other Monkeys. 



The monkeys I have collected, not of the genus Cercopithecus, 

 are Colohus satanas and two species of Cercocebus, besides Cerco- 

 cebus agilis mentioned above. 



The Colob is of local distribution, and I know nothing to tell 

 about it except some doubtful statements of natives. The same 

 is true of the Cercocebus called "kak" (? C. cdbigena). 



The " eka'afun " {Cercocebus coUat^is) is a little better known. 

 Monkeys of this species are not rare, but are not often killed. 

 They differ from those of the common kinds in that they often 

 descend to the ground to feed. Their call is very different from 

 that of the Cercopithecus monkeys. It is rather shrill, and ends 

 in an after-sound like that made while drawing in the breath or 

 gasping. 



The Galago Lemurs. 



These little creatures have a wonderfully tight grip ; their 

 clammy flattened fingers resemble the toes of tree-frogs. 



The " emam " (Galago alleni) is found in the daytime in hollow 

 trees, three or four huddled together asleep. The little " ojam " 

 {G. demidoffi) is similarly found asleep, three or four huddled 

 together in old nests of the squirrel " osen." Some people have 

 told me that the little Lemurs make their own nests, but it seems 

 more likely that these are only old squirrels' nests. The other 

 species, G. pallida, called " nsae," uses neither hollow tree nor old 

 squirrel's nest for a hiding-place in the daytime. They are found 

 sleeping in bunches of as many as half-a-dozen, clinging with their 

 arms around each other's bodies and around the branch of a tree. 

 A shrill squeaking or chirping, often heard at night among the 

 tree-tops of the forest, is referred by the natives to the " nsae." 

 They say that this noise is heard oftener near morning, and that 

 then the " father " is calling together the rest of the company, to 

 gather them into a huddle for the daytime. 



An " ojam " that I kept alive once for several days made a 

 chirping noise at night, as shrill as that of a cricket. In grasping 

 anything with its hind hand, the clawed finger was always folded 

 in the palm, under and not over the thing grasped. 



An " emam" that was brought to me alive showed great powers 

 in jumping. A monkey can jiimp outwards and downwards and 

 catch a branch, but this Galago could jump out and up and catch 

 hold of a branch. It died in the hot sunshine when I was away 

 from camp ; it had probably never felt sunshine before. 



The Pottos. 

 The two or three species of Ferodicticus of which the names
