parts scarcely different in shade from the dorsal, but without the

 whitish below; lateral glands marked by short grayish hairs which 

 are not noticeably different from the sides in color. 



Measurements. — Head and body, 90 mm. ; tail, 61 ; hind foot, 15.5. 



Skull : Condylo-incisive length, 23.3 ; breadth of brain-case, 10.7 ; 

 length upper tooth row, 1 1 ; condylo-incisive length of mandible, 15.8 ;

This species is a close ally of fumosa, but differs more in color 

 from the typical form from Mt. Kenia, than from the Mt. Ruwenzori 

 race, montis. The series of eight specimens from the type locality 

 show absolutely no color variation from the type and no intergrada- 

 tion takes place with the Kenia species. This is in agreement with 

 the isolated habitat. The species is confined to the extreme forested 

 summit of Mount Garguez which is isolated from the Kenia forest by 

 low bush covered desert in which no representative of the fumosa 

 group is known to occur. Fumosa and its allies are all forest species 

 known only from the highlands with the exception of schisticea of 

 the high veldt of the Athi Plains. On Mt. Garguez this race was 

 found from the lower edge of the forest at 5,000 feet to the summit, 

 7,000 feet.

 Mbololo Brown Shrew 



Type from the summit of Mt. Mbololo, Taita Hills, British East

 base ; feet and ears broccoli-brown, tail seal-brown above and some- 

 what lighter below but not distinctly bicolor. 



Measurements. — Head and body, 70 mm.; tail, 52; hind foot, 12.5. 



Skull: Condylo-incisive length, 19; width of brain-case, 8.7;
