of regulus being equal to minima of tragatus). Skull generally 

 lai-ger, 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 

 Avith any of the Avestern forms. 



Dentition. In one only, out of six paii'S 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) : p" present in five ; completely 

 wanting, and alveoli disappeared, in three (teeth unworn or 

 slightly worn). Oingula of the upper canine and j)"* always over- 

 lapping. This is unquestionably a higher stage than in nippon. 



Distribution. Darjeeling. Nepal. 



Technical name. Hodgson's cotypes of Rh. tragatvs (three 

 examples ; Nepal) are in the British Museum. 



14 c. Rhinolophus ferrum-equinum regulus, subsp. n. 



Uhinolophiis ferrum-equimim Hutton, P. Z. S. 1872, p. 698. 



Diagnosis. Size rather large, but width of horse-shoe modei'ute 

 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, largei-, the tooth- 

 rows longer. 



Dentition (4 skulls). In none of the skulls examined could I find 

 any trace of the lower pg, although they all have the teeth unworn. 

 In two skulls p^ is present, in two completely wanting. Gingula 

 of the upper canine and p^ always overlapping. This is the 

 highest stage of dentition in any race of ferrum-equinuni (in the 

 present grovip it is surpassed only by Rh. acrotis, but this species 

 is an Ethiopian modification not of the ferrum-equimmn type, but 

 of the afflnis type).

\^d. Rhinolophus ferrum-equinum proximus, subsp. n. (Plate 

 I\^. fig. 15.) 



Diagnosis. Size moderate, horse-shoe 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
