Dendrohyrax dorsalis Fraser. 



A fine specimen from Beni canght 6th of July 1913. 



Whether a small yonng withont dorsal spöt belongs to this species, or not, is im- 

 possible to decide. 



Elephas africanus cottoni Lydekker. 



A foetns with a length betwcen forehead and vent amounting to abont 30,5 cm. 

 (Pl. IX). 



As has been pointed out before, also by the present author concerning E. a. cyclotis 

 Matschie, the Elephant foetus comparativcly early assumes the shape of the fullgrown 

 animal to such a degree that the racial characteristics become conspicnous. This holds 

 good also in this case. The shape of the ear proves that this foetus belongs to the race 

 which has been named as above. A comparison between the accompanying figure of the 

 left ear of this foetus shows exactly the same shape as Lydekker' s figure in Proc. Zool. 

 Soc. London, 1907, 1, p. 390, on which the author quoted based his diagnose of this race. 

 The shape of the ear, especially the small size of the hanging lappet may also be seen 

 on a photo of a male Elephant shot by Capt. E. Arrhenius. 



The ear of E. a. cottoni is less oval than that of E. a. cyclotis Matschie from Came- 

 roon, but undoubtcdly both are nearly allied. Both have another characteristic in com- 

 mon viz. four hoofs on the hind foot. The present author stated 1 the presence of a fourth
