NO. 12 NEW INSECTIVORES FROM AFRICA HELLER 7 



Characters. — Most closely allied to provocax of which it is the 

 low country representative; differs by very much browner coloration, 

 shorter pelage and longer tail ; third unicuspid very slightly larger 

 than the second as in turba and its allies ; skull similar to provocax 

 but smaller. 



Coloration. — Dorsal coloration uniform vandyke-brown, the under- 

 pays but slightly lighter in color, broccoli-brown ; the color on the 

 sides merging imperceptibly into the underparts ; feet and ears drab ; 

 tail uniform in color, vandyke-brown; hair everywhere plumbeous 

 at base. 



Measurements. — Head and body, 95 mm. ; tail, 57 ; hind foot, 15.5. 



Skull : Condylo-incisive length, 23 ; width of brain-case, 10 ; length 

 of upper tooth row, 10.4; condylo-incisive length of mandible, 14.5; 

 depth at coronoid process, 5.5. 



This is a lighter, more brownish race of provocax which occurs 

 at the rather low elevation of 2,000 ft. on a stream, Northern Guaso 

 Nyiro, which rises in the Aberdare Range in the territory inhabited 

 by provocax. It has the second and third unicuspids of about equal 

 size, the latter never attaining twice the size of the second as in 

 fumosa. The second unicuspid viewed from the side looks dis- 

 tinctly larger than the third but when viewed from below where the 

 whole tooth can be seen its real relative size is seen to be equal or 

 slightly larger than the second. 



A series of nine specimens is in the collection, seven of these are 

 topotypes and the others are from neighboring localities on the 

 Isiola River and Northern Guaso Nyiro at the Government post. 

 Some of the specimens are rather darker than the type and are 

 quite intermediate in color with provocax. The specimens were all 

 secured in marshes or along the reedy borders of streams. 



CROCIDURA RAINEYI, new species 



Rainey Shrew 



Type from Mt. Garguez, Mathews Range, British East Africa, 

 altitude 6,000 ft; adult male; No. 181817, U. S. Nat. Mus. ; col- 

 lected by Edmund Heller, September, 191 1; original number, 4195. 



Characters. — Most closely allied to fumosa montis from which it 

 differs by larger size and decidedly more grayish coloration. Agrees 

 with the fumosa group in having the third upper unicuspid twice 

 the size of the second, but skull decidedly larger than in any other 

 member of the group. 



Coloration. — Dorsal coloration slate-gray with a broccoli-brown 

 suffusion and fine silvery ticking when viewed from behind, under-
