This specimen, which is about three-fourths grown, differs from 

 the adult in its mvxch greyer coloration, the annulations on each 

 hair being of a very pale grey. The colouring of the ears, however, 

 shows a faint yellowish tinge, and down the centre of the back 

 there is a slight trace of the dark colour chai-acteristic of the adult. 

 The underparts resemble those of the adult.
