THE BLACK-TAILED RAT 



(Rattus nigricauda) 



THE Black-tailed Rat is an inhabitant of the western 

 side of Africa. It is common in Angola, and 

 has been found as far south as South-West 

 Africa, and is quite common in the Kalahari. It 

 is a little over half the size of the common Brown 

 Rat, the body of an adult, including the head, 

 measuring only 7 inches. The tail is slightly 

 shorter than the head and body, and is naked at the 

 base, but towards the tip it is thickly covered with 

 long, shiny black hairs. The fur is long and coarse

 black ; sides yellower than the back ; under parts 

 pure white from the bases to the tips of the hairs. 

 Ears large and thinly covered with light grey hairs.

 daytime in the trees, only coming down on to the
