17. Rhinolophus refulgens , sp. n.

(Plate IV. fig. 6 a, b, c.)

Diagnosis. Skull and external characters, essentially of the lepidus-type. But brain-case somewhat higher in front, making the anterior slope of the sagittal crest, towards the postnasal depression, somewhat more abrupt. Forearm 40'6-41'5 mm.

Details. Very nearly of the same size as Rh. lepidus , but metacarpals, also proportionately, somewhat shorter; tibia shorter. The horse-shoe is, if anything, slightly broader.

Colour. ♀ ad., skin; Perak; Marcii; teeth almost unworn.

Very different from Rh. lepidus . General effect of the colour of the upper side: a dark shade of “ Prout’s brown ” with a tinge of “ hair-brown. ” On closer examination the fur of the upper side proves to be composed of two kinds of hair: longer, thinner, straight hairs, quite black; and somewhat shorter, crinkled hairs of a “ hair-brown ” colour; the mixture of the colours of these two kinds of hair produces the general effect. Base of hairs of upper side not lighter coloured. The fur of the upper side has a silvery reflection (iridescence). Under side between “broccoli-brown” and “ hair-brown. ” A spirit-specimen from Selangor (♂ ad., apparently the same age) is of the same colour.

Skull. In addition to the characteristic in the diagnosis: the “ maxillar width, ” across the antero-external corner of m’ (a character subject to exceedingly small individual variation in the species of the lepidus -section) is somewhat larger, giving this part of the skull a somewhat broader aspect: 6 ‘ 5-6 ’ 7 mm.; in lepidus 6 ’ 2 mm. Gap in front between the maxillary bones somewhat larger.

Dentition (two skulls). p3 external. p2 and p4 almost or quite

in contact, p2 in row; a small cusp, pointing inwards. In one specimen there is an extremely narrow space between p2 and p4 (the former place of p3).

Measurements. On p. 125.
