 Hose, Dec. 1891. 



This species is larger than any of the Indian pigmy shrews, 

 while it is far smaller than any other Oriental Pachyura as yet 

 described. Its short tail seems also to distinguish it from all 

 its allies. 



Mr. Everett has also collected a minute shrew in Sarawak, 

 but it proves to be a true Crocidura {s. s.), and, judging 

 merely from the description, I do not at present feel justified 

 in distinguishing it from the Javan C. monticolay Pet.
