106 MR. K. ANDERSEN ON BATS ; [May 16» 



specimen is slightly smaller than the smallest example of h'mia- 

 layanus I have seen, the tibia is fully as long as (if anything, a 

 trifle longei") than in the very lai-gest of these latter. On the 

 whole, I have but very little doubt that Rh. a. tyjncus will prove 

 to be much more closely related to the Burmese and Himalayan 

 forms than to any of the others. This would be an additional 

 evidence of the closer connection between the fauna of Java and 

 that of Indo-China and the Himalayas — closer than between Java 

 and the geographically nearer Sumatra, Malacca, and Borneo. 

 Distribution. Java. 



I'S g. RiiiNOLOPHUs AFFiNis PRiNCEPS, subsp. n. (Plate Til. 

 fig. 13.) 



Diagnosis. External characters : C4eneral size moderate ; tail 

 short ; but largest in the size of the horse-shoe and ears, and 

 the length of the tibia. Skull, nasal swellings, tooth-rows : the 

 extreme. 



Type, c? f>d. (in alcohol). Lombok, July 1896. Collected by 

 A. Everett, Esq. Brit. Mus. no. 97.4.18.13. 



Remarks. Placed side by side with Rh. a. himalayanus, this form 

 is strikingly diffei-ent ; the horse-shoe is no less than | bi-oader 

 than the broadest in himalayanus., and the skull is distinguishable 

 at a glance by its excessive width and the very broad nasal 

 swellings. But it must be remembered that siq^erans leads, not 

 up to, but decidedly in the direction of, princeps, and we do not 

 yet know the extreme limits of individual variation, either in 

 superans or in 2}'>"incep>s. 



When considering the geogi'aphical races * of Rh. affinis from a 

 more general point of view — and excludiug " typicus,'^ owing to the 

 peculiar' geological histoiy of Java-, as well as nesites, owing to its 

 having, j)robably, been influenced by somewhat exceptional con- 

 ditions, fai' away on the small isolated IST. ISTatunas, — the following 

 rule will be observed : the more southern or south-eastern the 

 habitat, the longer the ears, the broader the horse-shoe, the longer 

 the tibia, the larger the skull, the bi'oadei' the nasal swellings, 

 and the longer the tooth-rows. 



14. Rhinolophus ferrum-equinum Schreb. (Plate IV. figs. 

 14, 15.) 



Diagnosis. Sella jDandurate. p' completely external oi- wanting. 

 Ears more than 20 mm. Width of hoi\se-shoe less than 10 mm. 

 Forearm 52"8~63 mm.t 



Details. The ferrimi-equinum type originated from a Bat in all 



* I am unacquainted with Dobsou's Rh. atidamanensis (J. Al S. B. xli. pt. ii. 

 (1872) p. 337). The only specimen known is in the Calcutta Museum. It seems to 

 he a local representative of the affinis type. 



t The first and second characters, combined, are sufficient to distinguish ferrum- 

 equinvMi from all Oriental species of this group. The others are added to prevent 

 confusion with those Ethiopian species of the present group which also have the 

 sella pandurate and p- external or wanting {clfrosus, darlingi, acrofis ; avgwr and 

 deckeni). \
