For detailed measurements of the series see p. 226.
Specimens examined:- Six. three from the type locality ami
three from Sodong Jerok, 3,900 feet, also on the Idjen Massif.
The series obtained are all very uniform and differ very
markedly from that from Tjibodas. West Java, which we have
assumed to be the typical race in brighter general colouration.
the general hue being more brownish in the Tjibodas skin,
with the feet dark brown, not pure black, and the orbital ring
narrow. The greatest difference however, is in the tail, which
is ferruginous bay with a terminal black tip in the western
animal as in all others of the group which we have been
able to examine, though it should be noted that Hose 1 describes
a specimen, presumably from Borneo, which appears
to agree closely with the above form, though other authorities
specifically state that the tail of the Boolean race is rufous 01
ferruginous with a black tip.
The Penang race, on examination of a considerable series,
differs sufficiently from that inhabiting the mainland to receive
a name:
Petaurista petaurista penangensis, subsp. now
Type —Adult female (skin and skull), collected at Telok
Bahang, Penang Island, on 27th March. 1911 by E. Seimund.
Federated Malay States Museum Xo. 1413,11. Original
number 421 1.
Diagnosis. External characters precisely as in P.p. melanotus
from the south' of the Malay Peninsula but size smaller
and rostrum shorter and relatively broader.
Dimensions. See table on page 226.
Specimens examined. Three, all from the type locality.
Petaurista petaurista terutaus, Lyon.
Petaurista terutaus. Lyon, Proc. Biol. Soc. Washington.
xx, p. 17 (1907).
This race was described by Mr. Lyon from a single specimen
collected by Dr. W. L. Abbott in 1904.
Though the island has been visited by us on several
occasions we never succeeded in obtaining specimens until
December 1916. In that month, however, considerable wood
cutting was going on in the island opening up vistas in jungle
and we were so fortunate as to' obtain three adults.
