Geographic distribution. — So far as known Dendrogale occurs only 

 in Borneo and southeastern French Indo-China. As members of the 

 genus Dendrogale are very rare in collections, it is not at all probable 

 that this represents the extent of its distribution. When explora- 

 tions of the Malayan region are more Com- 

 plete it will probably be found elsewhere, 

 particularly Sumatra, where the rare genus 

 Ptilocercus was unknown for some time.

 present, claws small, plate 5.
