alecto, deepest in the vam/iyrus group. In the colour of the fur 

 the western Oriental species {fjujanteus, ariel) are nearest to the 

 ordinary style of the genus (light mantle and underparts) ; in 

 the Indo-^lalayan species of the vdinjyi/i'us type and in the chnjs- 

 aachen group the underparts are dark-coloured, in the alecto group 

 and the eastern " melanistic " races of Ft. vampjirns also the light 

 colour of the mantle has been more or less completely suppressed, 

 and in the Papuan neohibeniictts tyj>e the prevailing colour of the 

 upperside is some shade of russet, with the underparts similar or 

 paler. Taken together, these four groups cover almost the whole 

 of the Oriental region, Austro-Malaya, and N. and E. Australia.
