The type is a young animal with a black nose, but some adults
have a white nose patch. This species is not nearly allied to L.
petaurista as some writers have believed, the only similarity in color-
ing between them being the black frontal band going around the head.
It is nearer in coloring, so far as the dorsal region is concerned, to L.
FANTIENSIS.
