"This last does not properly belong to the present group of 

 species, but is only introduced to complete the list of those of 

 which it is necessary to mention the distinguishing characters 

 when describing 31. macJeari as ugav. All these species also differ 

 fi'om M. macleari in having the general colour grey or yellow 

 instead of rufous. 'So other described species could possibly be 

 confounded with the present most interesting new form, with which 

 1 have much pleasure in connecting the name of Caj)tain Maclear, 

 of H.M.S. 'Flying Fish,' to whom the Museum is indebted for 

 the Chi-istmas Island specimens." 



To this description it may be added that in the young the under 

 surface is much lighter coloured, and in one specimen is quite 

 white, the inner side of the fore and hind limbs being nearly so. 

 In the young, moreover, the long piles are not fully developed, 

 though they are visible among the fur. 



There is considerable variation in colour in this species. In 

 some specimens the back is darker and less rufous and the long 

 piles are less developed than in the tj-pical form.
