4:58 Mr. O. Thomas on 



l.'irge, and shows how little this part of Africa lias 

 been worked. No less than six species and subspecies have 

 proved to need description out of the small total of fourteen 

 represented. 



The most interesting form is the new mole-rat, Georychm 

 foxi, as the only species of the genus previously known in 

 West Africa is the widely different G. zechi of Togoland. 



The collection is therefore a very valuable accession to the 

 National Museum, and one most encouraging for the prospects 

 of further work in the Colony.

 lected loth May, 1910. Type. 



A very small pale species. Inner upper incisors practi- 

 cally unicuspidate. 



Size rather greater than in P. stampfl'd and miaascidus. 

 Fur about 4*5 mm. in length on the back. General colour 

 above near " wood-biown," below rather paler, the hairs both 

 above and below blackish slaty basally. Ears with a well- 

 marked squarish lobe at the base of their outer margin ; 

 tragus without basal lobule, broadest opposite the middle 

 of its straight inner margin. Wings from the base of the 

 outer toe. Calcar with a narrow calcareal lobule. 



Skull very delicate, low and narrow ; the brain-case nar- 

 rower than in P. stampflii. 



Upper incisors slender, unicuspid, the outer nearly as long 

 as the inner. (If a secondary cusp has been present on the 

 inner tooth it must have been very small and close to the tip 

 of the tooth.) Small premolar half internal, visible from 

 without. Lower incisors tricuspid, not overlapping.
