Prosciurillus murinus 177
natural history: Not much is known about P. leucomus.
Based on the similarity of its body plan to P. topapuensis and
P. alstoni, Musser conjectures that P. leucomus is a denizen of
the canopy. Its diet is probably soft fruits and insects. Fe-
males have three pairs of teats: two inguinal pairs and one
postaxillary pair.

Prosciurillus murinus (Müller and
Schlegel, 1844)
Celebes Dwarf Squirrel
description: This is the smallest of the endemic squirrels
on Sulawesi (Indonesia). It has dark brown upperparts; and
a tail fl ecked with buff , ochraceous, and black. It lacks ear
tufts, nape patches, and dorsal stripes. The tail is shorter
than the length of its body. The underparts are grayish. The
eyes are circled by buff y rings. It is very similar in coloring
and size to P. abstrusus, but P. murinus is smaller and the ears
are uniformly dark.
size: Sex not stated—HB 102–150 mm; T 55–120 mm; Mass
42–110 g.
distribution: The Celebes dwarf squirrel is ubiquitous all
over Sulawesi (Indonesia), except perhaps for the eastcen-
tral peninsula, where surveys for P. murinus have been poor.
It is also found on the surrounding islands of Pulau Talise
and Pulau Lembeh (Indonesia).
geographic variation: None.
conservation: IUCN status—data defi cient. Population
trend—no information.
