Muzzle.—Muzzle and noseleaf precisely as in Rhinolophus affinis, except that the ridge on muzzle beneath edge of horseshoe is developed into a distinct supplemental leaflet resembling those present in Hipposideros. In this respect Rhinolophus spadix resembles the animal from Burmah referred by Thomas to Rhinolophus rouxii;[27] but the terminal erect portion of the noseleaf is not shortened or in any way peculiar in form.
Ears.—The ears resemble those of Rhinolophus affinis, except that they are not as large.
Color.—Fur everywhere russet, slightly paler on ventral surface, darker and somewhat tinged with hazel above. Ears and membranes dark brown.
Skull and teeth.—The skull and teeth exactly resemble those of mainland specimens of Rhinolophus affinis except for their uniformly smaller size.
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.
