A black-coloured species, in this respect differing entirely 

 from any other members of tlie pjenus. 



General colour, including limbs and tail, dark bluish black 

 except for a large triangular patch of white on the crown, 

 which is continued as a white dorsal stripe down to the middle 

 of the back ; and in one example there are traces of irregular 

 white markings on the nose, chin, and around the mouth. 

 Individual hairs, both black and white, uniformly coloured 

 for their entire length. 



Skull very similar in appearance to other species of 

 Georyclius. Nasals almost parallel, ending in a broad 

 rounded suture a little behind the lachrymal projection. 

 Ascending processes of premaxillaries ending in points about 

 1*5 mm. behind the nasals posteriorly, and not closing in 

 towards the middle line. Anteorbital foramina higher than 

 broad, almost elliptical in shape.

Hah. Kataba River, Upper Zambezi, North-western 

 llhodesia. 



Cotypes. Two males. Collected by T. N. Micklem on the 

 25th and 28th Aug., 1908. 



Very common ; I saw about a dozen, all of which were 

 coloured similar to the three skins brought back, including 

 the white markings. These three were dug out of the ground 

 by natives. They burrow and throw up heaps of sand 

 similar to the English mole.
