Show 90 MR. K. ANDERSEN ON BATS [May 16, It looks like a dark and a light " phase." The dark phase differs from that of Rh. borneensis, chiefly, in having the under side of the body much lighter, in strong contrast to the colour of the upper side, and in having also the base of the hairs of the upper side much lighter. The light phase is, as will be seen from this description, totally different from the " cadmium orange " phase of borneensis (and more approaching the light phase of Rh. affinis himalayanus). Skull. Essential characters as in Rh. borneensis, but the median anterior nasal swellings somewhat more distinctly marked off from the lateral anterior swellings. Dentition. p3 external; p., and p4 almost in contact; p2 in row, cusp extremely small. Measurements. On p. 92. Distribution. Biserat (Jalor, Malay Peninsula). Laos Mts. (Siam). Technical name. The type is in the British Museum. Remarks. From the Laos Mountains, Siam, I have seen one dried skin only (Tomes Collection); it looks like a light-coloured phase of Rh. malayanus; the nasal swellings of the (fragmentary) skull have the shape characteristic of this species. But fresh material from that region is desirable. 9 . R h in o lo p h u s n e r e is , sp. n. (Plate III. fig. 7 a, b, c.) 11 Rhinolophus rouxii ? " (non Temm.) Gerrit S. Miller, Jr., Proc. Wash. Ac. Sci. ii. (Aug. 20th, 1900) p. 234. Diagnosis. Allied to Rh. borneensis, and of about the same size, but with much larger skull and teeth. Lower leg considerably longer: 21 mm. Tail comparatively very short: 17 mm. Forearm about 45 mm. Details. In addition to the above :-The second phalanx of the third finger is more than 1| the length of III.1 ; this is the first time we have to note a decisive lengthening of III.2; in Rh. borneensis, as in all the foregoing species, I I I .2 (always, in this paper, measured without the terminal cartilaginous rod) is invariably less than 1 h the length of III.1; compare with this Rh. stheno, thomasi, affinis, ferrum-equinum. IV .1 is comparatively shorter than in Rh. borneensis, only about \ the length of the metacarpal of the same finger ; compare with this Rh. stheno. Colour. $ ad. (type) ; September; teeth almost quite unworn; first preserved in formalin, now in alcohol; probably unfaded.- " Mars-brown " above ; base of hairs " ecru-drab " ; of a peculiar yellowish " drab" beneath (? the yellow due to the influence of formalin). Skull. Of tlie same general shape as in Rh. borneensis, 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 differences (the ciphers in brackets are the measurements of eleven skulls of Rh. borneensis) :-total length, inion to front |
