there it shades more and more into rufous in a backward 

 direction; in some specimens this colour is more terra cotta 

 brown, in some more rust brown. The lower parts are grizzled 

 in a similar way as the upper bnt much paler. The shortness 

 of the fur easily distinguishes this Mongoose as well from M. ich- 

 neumon as from M. cafer. From M. angolensis (Bocage)^ it dif- 

 lers in the colouration of the fur, the former having the rings 

 of the hair »roux» and the greater part of the tail »d'un 

 roux ardent uniforme». The tail in M. angolensis is also almost 

 as iong as head and body, which is not the case with the 

 Congo Mongoosesa the following measurements prove.
