quire no further mention, except to notice the total absence of the 
whitish patch on the under parts, where the fur is of a uniform 
greyish-brown colour. With the exception of this difference, EZ. 
schoénsis might, as far as external appearance is concerned, be fairly 
described by stating it to be a pigmy FL. gambianus. 
The cranium requires special mention. It is short, and has the 
cerebral region rounded and devoid of crests or ridges, and instead 
of being, as in the more typical forms, shorter than the facial portion 
of the skull, it is longer, that part in front of the orbit not being 
more than half the length of that which is behind it. But while its 
general outline is less typical of the form of cranium which charac- 
terizes the genus, the parts taken in detail are not less typical. 
Thus the small development of the supra-orbital process, taken as a 
characteristic feature of the genus, is more remarkable in this species 
than in any other. It may be said to be directed backwards, and 
adherent, so that only an extremely small point is free. The space 
between the orbits is much wider in relation to the size of the skull 
than in the larger species. The palate, instead of having transverse 
ridges and furrows, is smooth, with a slight prominence behind the 
canines, of a hastate form, with the point directed backwards; 
behind this is a shallow depression of similar form, with its point 
extending almost to the hind margin of the bony palate. On each 
side of this point, and just within the raised rim which bounds the 
palate, are two ovoid smooth hollows.
