114 TREUBIA VOL. II, 1. 
Mr. H. C. ROBINSON, of Kuala Lumpur, who has instigated such 
extensive collecting in the Malay Peninsula, tells me that although every 
effort has been made to trap water-shrews, nothing of the sort has been 
found in the area he is concerned with. So that there would seem to be 
a complete geographical gap between the ranges of Chimarrogale and 
what I have now called Crossogale. 
The broadened anterior incisors of Crossogale are modified to form 
together a double-pointed fish-catching weapon curiously similar in appearance 
and function to that of the fish-eating rats (/chthyomys and allies), where 
the widely separated outer corners of the incisors make two prongs, of 
obvious use in the capture of small fish. 
On the other hand the front incisors of Chimarrogale are each tapered 
and pointed, and close together, so that the pair form a comparatively 
simple gaff.
