 exceedingly long tail with its purplish tip. It is perhaps nearest to C.

The type of this species is in the British Museum preserved in 

 spirits. It is quite a young individual, the canines and last molar just 

 showing. I have therefore taken the measurements from an adult 

 individual, as giving a more correct idea of the animal's size.
