The area of the African continent north of the 20° N. lat,, and eastward of the 
25° E. long., is devoid of any representative of the Simiidae and Cercopithecidae. 
The explanation of this is to be sought for in the almost total absence of either scrub 
or trees over that area, owing to the circumstance that it lies beyond the influence of 
the periodical rains and is practically rainless. 
The region to the south of the great bend of the Nile between Old Dongola and 
Abu Hamed is more or less favoured by regularly recurring rains, meagre and 
uncertain it is true, for some degrees to the south of lat. 17°, but increasing in volume 
and certainty further southward. 
Our knowledge of the Cercopithecidse which inhabit the area known in ancient 
times as Ethiopia is still in a most unsatisfactory condition, but now that the country 
is thrown open to civilization its fauna will doubtless soon claim the attention of 
zoologists. 
l\vo distinct genera of the family Cercopithecidae are represented on the monuments 
of Egypt, viz. Cercopithecus and Papio ; but when an attempt is made to identify the 
figures with the existing species representing these genera, the subject is found to be
