ON OUR KNOWLEDGE OF THE CHIROPTERA, ETC. 175 



Suborder II.— MICROCHIROPTERA. 

 Family Rhinolophid^. 



lihinolophus luctus, Temm. 



Hab. Mount Willis, Java, 2500 feet (Baron v. Hiigel). This new 



locality for B. liictus also indicates, as I have previously remarked, that 



this species appears to be restricted to the highlands of the countries 

 which it inhabits. 



Bhinolophus acuminaius, Ptrs. 



To the localities of this species add Laos, Siam, (M. Harmand, Paris 

 Museum). 



Rhinolophus affinis, Horsfield. 

 Add also Cochin China (M. Harmand, Paris Museum). 



Bhinolophus minor, Horsfield. 



Dr. W. Peters remarks ' that I have unaccountably confounded Bh. 

 cornnhis, Temm. with this species, which, he states, is to be distinguished 

 from it, as Horsfield's figure shows, by the superior margin of the central 

 connecting process behind the sella being obtusely rounded ofi", as in 

 Bh. affinis, and not sharply pointed. 



The following notes will, I think, sufficiently explain why I still regard 

 Bh. cornutus, Temm. a synonym of EJi. minor. 



1. With respect to Horsfield's figures they are not only badly executed, 

 but were taken, as the types show, from very badly preserved specimens, 

 and therefore cannot be depended upon as correct. 



2. The type of Bh. minor (lately in the collection of the India Museum, 

 and now transferred to the British Museum) agrees so closely vrith 

 Horsfield's description that there can be no doubt of its being really the 

 type of the species. In it the part of the noseleaf referred to above is 

 very different in shape from the corresponding part in Bh. affinis (to 

 which Dr. Peters likens it), it is triangular and pointed, very like that of 

 Bh. landeri (see ' Catal. Chiropt. Br. Mus.' pi. vii. fig. 9), and quite 

 similar to that of two specimens from Japan, lately added to the collec- 

 tion of the British Museum, which I have no hesitation in recognising as 

 examples of Bh. cornutus, Temm. But in other specimens of Bh. minor, 

 especially in those of smaller size, I have observed that the superior margin 

 of the posterior connecting process is even more acute, in some exceedingly 

 so, constituting the variety Bh. pnsillus, Peters, (not Temminck) ; in 

 others, still smaller, the terminal portion of the posterior lancet-shaped 

 nose-leaf is broad, with straight sides, forming almost an equilateral 

 triangle, very different from the corresponding narrow terminal process 

 in other individuals, constituting another variety, which, until lately, I 

 considered a distinct species and named Bh. garoensis. As a further indi- 

 cation of how liable this species is to vary, as I have previously remarked, 

 the position and size of the second lower premolar is very uncertain, being 

 found in some small individuals of moderate size and standing in the 

 tooth-row, in larger specimens minute and quite external, and vice versa.
