_Measurements._--External measurements of type: total length, 70
(85[28]); tail 21 (23); tibia 17.6 (24); foot 8 (10); calcar 12 (13);
forearm 43 (51); thumb 8 (8.6); second digit 32 (40); third digit 64
(77); fourth digit 53 (61); fifth digit 54 (63); ear from meatus 17
(20); ear from crown 14 (17); length of noseleaf from lip 13 (16);
greatest width of noseleaf 8 (9).
Cranial measurements of type: greatest length 18 (23); basal length
16 (20.4); basilar length 14.6 (18); zygomatic breadth 9 (11); least
interorbital breadth 2.4 (2.4); greatest length of braincase 10.4
(13); greatest breadth of braincase above roots of zygomata 8 (9.4);
frontopalatal depth (at middle of molar series) 4 (4.8); depth of
braincase 6 (7); mandible 11.8 (15); maxillary toothrow (exclusive
of incisor) 6.8 (9); mandibular toothrow (exclusive of incisors) 7
(9.8).
_Specimens examined._--Three (one skin), all from the type locality.
_Remarks._--_Rhinolophus spadix_ is so readily distinguished from
its relatives of the _R. affinis_ group that it needs no special
comparisons. It is a much smaller animal than the species from the
Anambas that I recently referred to _R. rouxii_.[29] In color the
latter is a dull brown not in the least resembling the russet of _R.
spadix_.
CYNOPTERUS MONTANOI Robin.
1894. _Cynopterus marginatus_ THOMAS and HARTERT, Novitates
Zoologicæ, I, p. 655. September, 1894 (Sirhassen and Bunguran).
1899. _Cynopterus montanoi_ MATSCHIE, Die Fledermäuse des
Berliner Museums für Naturkunde, p. 75. August, 1899. (Natuna
record of _C. marginatus_ placed in synonymy of _C. montanoi_.)
Five specimens (three skins) from Sirhassen. These agree so closely
with a skin and two bleached alcoholic specimens from Singapore,
which I suppose to be the same as the Malaccan _Cynopterus montanoi_,
that without more material it is impossible to distinguish the Natuna
animal from that of the southern extremity of the Malay Peninsula.
_Cynopterus montanoi_ as thus understood differs from _C. angulatus_
Miller[30] of Lower Siam in its more slender skull and in the
absence of the white border of the ear, and from _C. titthæcheilus_
(Temminck) of Sumatra and Java in its conspicuously smaller size.
PTEROPUS VAMPYRUS (Linnæus).
1894. _Pteropus vampyrus_ THOMAS and HARTERT, Novitates
Zoologicæ, I, p. 655. September, 1894 (Bunguran).
1895. _Pteropus vampyrus_ THOMAS and HARTERT, Novitates
Zoologicæ, II, p. 489. December, 1895 (Bunguran).
Six skins from Bunguran.
? PTEROPUS HYPOMELANUS Temminck.
1894. _Pteropus hypomelanus_ THOMAS and HARTERT, Novitates
Zoologicæ, I, p. 655. September, 1894 (Sirhassen).
1895. _Pteropus hypomelanus_ THOMAS and HARTERT, Novitates
Zoologicæ, II, p. 489. December, 1895 (Pulo Pandak, Pulo
Panjang and Pulo Laut).
