6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60 



fourth upper unicuspid on each side. These adventitious teeth have 

 peculiar compressed knife-like crowns which are wedged in between 

 the normal teeth much like the blade of a knife might be inserted in 

 the tooth row. 



CROCIDURA SUAHELiE, new species 



Strand Shrew 



Type from Mazeras, British East Africa; adult male; No. 181815, 

 U. S. Nat. Mus. ; collected by Edmund Heller, December 17, 191 1; 

 original number, 4875. 



Characters. — Agreeing with vol in the enlarged character of the 

 second unicuspid in comparison to the third, but size of body much 

 larger and coloration broccoli-brown, not slaty. 



Coloration- — Dorsal coloration uniform broccoli-brown not sharply 

 defined against the drab-gray of the underparts; hair everywhere 

 slate-gray at base; lateral glands defined by a conspicuous line of 

 white hairs; feet somewhat lighter than body, drab in color; tail 

 uniform in color with the dorsum and clothed by short brown hair 

 and scattered long white hairs on the basal two-thirds. 



Measurements. — Head and body, no mm. ; tail, 69; hind foot, 16. 



Skull : Condylo-incisive length, 26.5 ; width of brain-case, 10.5 ; 

 interorbital width, 4.8; upper tooth row (crowns), 11.8; condylo- 

 incisive length of mandible, 16; depth (coronoid process to ramus), 



7-3- 



Dentition crowded, causing the second unicuspid to appear decid- 

 edly larger than the third from the side. When viewed from below 

 they are seen to be actually the same in size. 



This species although possessing the dental characters of vol does 

 not seem to intergrade with it in size or coloration. It is a decidedly 

 larger species approaching very closely Uavescens in actual size of 

 body and teeth, but differing by the enlarged second unicuspid from 

 the members of that group. 



A series of twenty from the type locality are in the collection. 

 The color variation is almost nil, except in very immature speci- 

 mens which are uniform grayish.
