LI. — Two new African Shrews. 

 By Wilfred H. Osgood. 



As a further result of studies at the Natural History Museum 

 two new shrews of the genus Crocidura have been found, 

 which, like the rodents described in the March number of the 

 ' Annals,' are named at the instance of Mr. Oldfield Thomas. 

 Both are given subspecific rank, not only to indicate their 

 positions in the large and unrevised genus to which they 

 belong, but also because experience with groups more com- 

 pletely known has shown that closely related continental 

 forms are more often proved to be connected by gradations 

 than otherwise.
