description: 9. Rhinolophus nereis, sp. n. (Plate fig. 7 <i>a, b, c</i>.) “ Rhinolophus <i>rouXii</i> ? ” (non Temnm.) Gerrit S. Miller, Jr., Proc. Wash. Ac. Sci. ii. (Aug. 20th, 1900) p. 234. <i>Diagnosis.</i> Allied to <i>Rh. borneensis,</i> and of about the same size, but with much larger skull and teeth. Lower leg considerably longer: 2 mm. Tail comparatively very short: <b>7</b> mm. Forearm about 45 mm. <i>Details.</i> In addition to the above:—The second phalanx of the third finger is more than 1 <i>k</i> the length of III.1; this is the first time we have to note a decisive lengthening of III.2; in <i>Rh. borneensis,</i> as in all the foregoing species. III.2 (always, in this paper, measured without the terminal cartilaginous rod) is invariably less than 11/2 the length of III.1; compare with this <i>Rh. stheno, thomasi, affinis, ferrum-equinum.</i> IV.1 is comparatively Shorter than in <i>Rh. borneensis,</i> only about 5 the length of the metacarpal of the same finger; compare with this <i>Rh. stheno.</i> <i>Colour.</i> &amp;female; ad. (type); September; teeth almost quite unworn; first preserved in formalin, now in alcohol; probably unfaded.— “ Mars-brown <i>”</i> above; base of hairs “ ecru-drab <i>”</i>; of a peculiar yellowish “ drab <i>”</i> beneath ('? the yellow due to the influence of formalin). <i>Skull.</i> Of the same general shape as in <i>Rh. borneensis,</i> but much larger, with considerably larger teeth, and therefore longer tooth-row; orbital constriction very narrow. The following measurements, in millimetres, will give a more precise idea of the <i>differences</i> (the ciphers in brackets are the measurements of eleven skulls of <i>Rh. borneensis)</i>: <i>—</i> total length, inion to front of canine 2 "2 [18 <i>’</i> 2-20"; length of brain-case, inion to anterior point of proencephalon 3 <b>’</b> 7 [11 <i>’</i> 3-2 <b>’</b> 5[; width of brain-case above zygomata 9 <i>’</i> 5 [*9 —8'21; zygomatic width 10'8 [9—9'9j; maxiliar •width, across antero-exterior corners of m3 8’5 [6'8-7'2]: interorbital constriction 2 <i>’</i> 2 [2'4-2'8]; palatal bridge, median length 2 <i>’</i> 6 [<i>’</i> 8-2'3]; maxillar tooth-row 8’7 [7-7'6]; extreme width of m1 2'2 [1'5-1'9J. <i>Dentition.</i> I have not seen the mandible of this Bat. p2 in row; cusp almost imperceptible. <i>Measurements *.</i> On p. 92. <i>Type.</i> &amp;female; ad. (in alcohol). Pulo Siantan. Anambas Group: September, 1899. Collected by Dr. AV. L. Abbott. Un. St. <i>Nat</i>. Mus. no. 101714. <i>Remarks.</i> As already pointed out above, the Bats of the <i>borneensis</i> type inhabiting the S. Natuna and Karimata groups, rather <i>close</i> to the north-western and western coasts of Borneo, are so extremely like the typical <i>borneensis</i> as to be, perhaps, scarcely separable. But <i>farther westwards,</i> on the much more <i>isolated</i> Anambas Islands, the <i>borneensis</i> type has developed into the present, peculiarly modified species. In the lengthening of III.-, the shortening of IV.1. and the shortening of the tail (compared with the tibia). <i>Rh. nereis</i> has taken the same course as the still more western <i>Rh. stheno</i> (described below). But the shape of its skull sufficiently proves it to be an offshoot, not of that species, but of <i>Rh. borneensis.</i> Compare with this the “ remarks under <i>Rh. stheno.</i>
