20 Field Museum of Natural History — Zoology, Vol. X. 



Characters. Allied to Crocidura argentata fischeri, with which it 

 agrees in the general color of the upperparts, but tail decidedly longer 

 and more extensively dusk}^ on the upper side. Upperparts in fresh 

 pelage fawn color with a fine ve^rmiculation of lighter (almost ecru 

 drab) ; underparts and upper lip dull grayish white, the bases of the 

 hairs mouse gray to smoke gray; feet white; tail above broadly dusky 

 brownish, below whitish for proximal two- thirds, mixed dusky and 

 whitish for terminal third. Skull similar to that of fischeri but smaller 

 and with a more compressed rostrum and decidedly smaller teeth; 

 second unicuspid very slightly smaller than third. 



Measurements. Type: Total length 150; head and body 90; 

 tail vertebrae 60; hind foot 15. Skull of type: Condylo-incisive 

 length 22; length of toothrow 9.6; maxillary width 6.8; greatest 

 width of m' 2.3. 



Remarks. The few differences between this species and C. a. fischeri 

 are so pronounced that it is not possible at present to include it with 

 that form as a subspecies of argentata. The difference in the size of 

 the teeth is quite decided and there is no indication of gradation. 

 The color, however, is about as in fischeri except that the tail is darker. 



Crocidura allex sp. nov. 



Type from Naivasha, British East Africa. No. 16820 Field 

 Museum of Natural History. Adult male. Collected January 31, 

 1906, by E. Heller. 



Characters. Allied to C. bottegi and possibly to C. cunninghamei ; 

 size larger than in bottegi with larger skull and teeth; color lighter 

 especially on underparts and feet; size somewhat smaller than in 

 cunninghamei; skull shorter with a higher, more vaulted braincase; 

 teeth smaller. Upperparts dull brown; underparts buffy gray; feet 

 grayish, practically same color as underparts; pelage longer and* 

 coarser than in cmniiHghamei. 



Measurements. Type: Total length. 109 ; head and body 64; tail 

 vertebrae 45; hind foot 12. Skull: Greatest length 17.1; greatest 

 breadth 7.7; maxillary breadth 5.2 ; postpalatal length 7.9; toothrow 

 7.15; greatest width m^ 1.7. 



Remarks. The shape of the skull in this species is more like that of 

 bottegi than that of cunninghamei and its teeth though larger are more 

 like those of bottegi. C. cunninghamei has a longer, narrower skull 

 and a flatter braincase, and its teeth are scarcely smaller than in small 

 specimens of hildegardeae.
