Show 112 MR. K. ANDERSEN ON BATS . [May 16, of regulus being equal to minima of tragatus). Skull generally larger, and with broader nasal swellings. (3) Compared with the western races: The large size, broad liorse-shoe, shorter tail, large skull, broader nasal swellings, and longer tooth-rows prevent it, in most cases, from being confused with any of the western forms. Dentition. In one only, out of six pairs of mandibles, p3 is present on both sides; in two (teeth unworn, or very slightly worn) on one side (alveolus disappeared on the other side); in no less than three completely wanting, although the teeth are either quite or almost unworn. A similar high development of the upper teeth (eight skulls): p2 present in five; completely wanting, and alveoli disappeared, in three (teeth unworn or slightly worn). Cingula of the upper canine and p4 always overlapping. This is unquestionably a higher stage than in nippon. Distribution. Darjeeling. Nepal. Technical name. Hodgson's cotypes of Rh. tragatus (three examples; Nepal) are in the British Museum. 14 c. R h in o lo p h u s f e r r um - e q u in u m r e g u lu s , subsp. n . Rhinolophus ferrum-equinum Hutton, P. Z. S. 1872, p. 698. Diagnosis. Size rather large, but width of liorse-shoe moderate only. Skull large and broad, with long tooth-rows, but narrow nasal swellings. Details. Compared with the western races: The large size, combined with the short tail, will, in most cases, make it readily distinguishable. The skull is, almost invariably, larger, the tooth-rows longer. Dentition (4 skulls). In none of the skulls examined could I find any trace of the lower p3, although they all have the teeth unworn. In two skulls p2 is present, in two completely wanting. Cingula of the upper canine and p4 always overlapping. This is the highest stage of dentition in any race of ferrum-equinum (in the present group it is surpassed only by Rh. acrotis, but this species is an Ethiopian modification not of the ferrum-equimim type, but of the affinis type). Type. <5 ad. (in alcohol). Masuri. Collected and presented by Capt. Hutton. Brit. Mus. no. 79.11.21.153. Distribution. Almora. Masuri. 14 d. R h in o lo ph u s f e r r um - e q u in um p r o x im u s , subsp. n. (Plate IV. fig. 15.) Diagnosis. Size moderate, liorse-slioe very narrow, tail short, Skull small and slender, with very narrow nasal swellings and short tooth-rows. Details.-(1) Compared with the typical form : Although being of the same size as the larger and medium-sized individuals of the typical form, proximus has a very short tail; in so far, it might, very properly, be characterised as a " typical " ferrum-equinum |
