Many living specimens of this Duiker have also been received by the Zoo- 
logical Society of London, besides those mentioned by Mr. Ogilby. Although 
in nature shy and retiring it does well in captivity, and becomes very tame 
when petted. It has frequently bred in the Society's Menagerie, and specimens

It is also well known in several of the Zoological Gardens on the Continent.

Maxwell’s Duiker appears to extend from Senegal and Gambia all along 
the West Coast of Africa to the mouths of the Niger. From Senegal, as 
already mentioned, it has been received in Paris, and from the Gambia living 
specimens were brought by Whitfield for the Derby Menagerie. From Sierra
