The splendid reddish white color of the under surface 

 of the body and inner sides of limbs distinguishes this spe- 

 cies , the basal part of the hair being not grey or slate- 

 colored like in other species.

In our Museum there are specimens from Java, Sumatra, 

 Banka, Billiton and Borneo (Pontianak , Banjermassing and 

 Karau-river). They have been described and figured by 

 Muller and Schlegel in the well known » Verhandelingen 

 van de Natuurkundige Commissie" under the specific title 

 melanotis: the figured individuals being from Java. I see 

 in Hose's » descriptive account", p. 52, that the specimen 

 in the British Museum referred by Waterhouse to soricinus 

 is also a Javan specimen.
