Remarks. The cranial and dental characters given above are 

 constant in the small number of skulls examined. Seven adult 

 skulls from East Africa and five from Egypt have been available. 

 Apparently none of the South and West African forms need to be 

 considered as all are different in color. M. i. angolensis Bocage is 

 practically identical with the East African form in cranial characters 

 but differs widely in color. M. i. parvidens Lonnberg from Lower 

 Congo has even weaker teeth than funestus and as described is further 

 characterized by small size, short tail, and short hair. M. i. cajjer 

 differs still further both in color and in cranial characters. Typical 

 ichneumon of northern Egypt is therefore the only form with which 

 East African material needs close comparison. 



Sylvisorex mundus sp. nov. 



Type from Kijabe. British East Africa. No 16801 Field Museum 

 of Natural History. Adult male. Collected January 24, 1906, by E. 

 Heller. 



Characters. Similar to Sylvisorex granti of Mount Ruwenzori ; 

 size larger; tail relatively shorter; braincase narrower and slightly 

 deeper; rostrum more slender; second unicuspid relatively small. 

 Skull and teeth smaller and braincase relatively wider than in 5. 

 sorella. Upperparts dark blackish slate; underparts slightly paler 

 than upper; hairs of back 4-5 mm. in length; feet sooty brownish, 

 darkest on the inside; tail blackish above, somewhat paler below. 



Measurements. Type: Total length 129; head and body 70; 

 tail vertebrae 59; hind foot 12.5. Skull of type: Greatest length 

 17.2; greatest breadth 8.45; postpalatal length 7.4; greatest width 

 between outer sides of molars 5.3; length of upper toothrow 7.1. 



Remarks. The types of the species allied to this form, 5. granti 

 and 5. sorella, are both in alcohol, so it is not possible to determine 

 their exact natural coloration, but they are sufficiently distinguished 

 by cranial characters. Possibly further collections may demonstrate 

 that all three are connected by gradations. 



Crocidura voi sp. nov. 



Type from Voi, British East Africa. No. 16942 Field Museum of 

 Natural History. Adult male. Collected April 12, 1906, by E. 

 Heller. 



Characters. Size rather large; tail relatively short, scarcely half 

 as long as head and body; general color slaty above and dull yellow- 

 ish or grayish white below, the light and dark areas quite sharply 

 contrasted; upper lip extensively whitish; feet white. Skull large, 

 long, and narrow; teeth heavier than in any other east African shrew 

 except nyansce; second unicuspid decidedly larger than third.
