THE SLOW-LORIS. 25 
brown; circle round the eyes dark brown ; a white line down the 
nose between the eyes; oral patch, including the ears, brown. 
The Slow-Loris varies greatly in size and colour in the 
different regions it inhabits, and its varieties have been recog- 
nised by many naturalists as distinct species. 
Every shade of colour occurs among specimens from different 
habitats. ‘The colour varies between rufescent grey, or greyish- 
rufous, or white (with a brown tinge showing through from 
below) and silvery grey. The dorsal stripe varies from rufous 
to’ dull grey or even black, .expanding out, or not, on the 
crown of the head, arms, and cheeks, bifurcating to the orbital 
rings and ear-patches, or to one or other only. Sometimes the 
dorsal stripe and face-markings are wanting altogether. Under 
side varying from pale rufescent grey to light rufous or duli 
grey. Length of head and body varying from 1234 to 16 
inches. 
“Tt is an interesting fact,” observes St. George Mivart, “that 
as far as concerns the skull and dentition, the Asiatic Vycticebus 
far more resembles the African Ferodicticus than it does its 
Oriental neighbour Zov7s.” 
Distribution —The Slow-Loris has a comparatively wide and 
interrupted range. It is common in the dense mountain 
forests of Assam and Burma (where it has received the dis- 
tinctive appellation of VV. dengalensis), as well as in Tenasserim 
and the Malayan Peninsula. It has also been obtained in 
Siam and Cochin-China, whence it has been described as 
a distinct species (JV. cénerews), from its silvery-grey fur; while 
it also occurs—somewhat reduced in size—and often (but not 
invariably) without the upper incisor teeth—in the islands of 
Sumatra, Java, and Borneo with its surrounding islet groups,
