Crocidura butler i, sp. n. 



A medium-sized species, with a short, white, incrassated 

 tail. 



Fur soft and fine; hairs of back rather less than 4 ram. in 

 length. General colour above near " drab-^^rey," the usual 

 grey of the upper surface with a certain suffusion of *' dcru 

 drab.'"* Under surface soiled buffy, the hairs brownish slaty 

 for three-fourths their lenoth^ their tips cream-buff, which 

 gives a rather unusual yellowish appearance to the whole 

 underside ; no line of demarcation on sides. Lateral gland 

 prominent, short-haired, cream-buff. Hands and feet white. 

 Tail short, very much incrassated throughout, its hairs, both 

 shorter and longer, white or with a slight buffy tinge. 



Skull of nearly the same length as that of specimens from 

 the same place referred by Mr. Wroughton to C. sericea^ 

 Sund., but the brain-case is markedly shorter. Second antl 

 third unicuspids subequal in area, the former the higher of 

 the two. 



Dimensions of the type (measured on tlie skin) : — 



Head and body 78 mm.; tail 34; hind foot 13. 



Skull: condylo-incisive length 24; anterior breadtli 7'6 ; 

 posterior breadth 9*9 ; interorbital breadth 4*5 ; upper tooth- 

 row 10*5 ; tip of postglenoid process to hinder end of 

 condyle 9'4'^.

Type. Adult male. B.M. no. 8. 4. 2. 10. Original num- 

 ber 33. Collected 7th March, 1907, and presented by A. L. 

 Butler, Esq. 



This striking little shrew, which I have named in honour 

 of its discoverer, is readily recognizable by its short, whitish, 

 incrassated tail and its more or less buffy underside. 



Tatera hopkinsoni, sp. n. 



A rather small species, with unusually short broad feet. 

 Size decidedly less than in the other Gambian species, 



* This measurement,, easily taken with exactitude, gives an idea of the 

 length of the brain-case. The direct mensurement on the upper surface 

 is less easy to take accurately.
