Rhinolophus ferrum-equinum (partim) Dobson, l. s. c.

Diagnosis. Size largest, horse-shoe very broad. Skull and tooth-rows: the extreme.

Details.— (1) Compared with nippon : see this form, supra. (2) Compared with regulus: On an average larger, with markedly broader horse-shoe (but no sharp line of separation, the maxima

colour.

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 horse-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, p.(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 n'vppon.

Distribution. Darjeeling. Nepal.

Technical name. Hodgson’s cotypes of Rh. tragatus (three examples; Nepal) are in the British Museum.
