18 Fretp Museum or Natura. History — Zoo.ocy, Vor. X. 
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. 7. angolensis Bocage is 
practically identical with the East African form in cranial characters 
but differs widely in color. M. 1%. 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. 1. caffer 
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 S. 
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 vertebre 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, S. granti 
and S. 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 nyans@; second unicuspid decidedly larger than third.
