82 MR. K. ANDERSEN ON BATS [ May 16, 
4, RHINOLOPHUS NANOS, sp.n. (Plate IIT. fig. 3.) 
Rhinolophus megaphyllus (non Gray), var. (2 (partim), Dobson, 
Cat. Chir. Brit. Mus. (1878) p. 111 (Goram). 
Diagnosis. Essential cranial characters as in Rh. truncatus, but 
brain-case remarkably slender. Sella so slightly constricted as to 
be practically parallel-margined. Small: forearm 43-3 mm. 
Detwils. This species marks a further step towards the celebensis- 
borneensis type. Externally Rh. nanws is exceedingly like these 
two species, but the skull is of the stmplex type. 
The sella (compared with that of the foregoing three species) is 
considerably reduced in breadth; its width at the base is but very 
little greater than at the summit; the constriction at the middle 
is much reduced (it requires some attention not to be overlooked); 
and the whole of the sella therefore might very well be called 
almost parallel-margined; summit completely square-cut (there 
will probably, in a large series, be some individual variation 
in this respect). The horseshoe, too, is a little narrower. Lancet 
almost cuneate, the lateral margins being but very slightly 
coneave. The sizeof the ears, both length and breadth, is reduced ; 
the tip slightly more attenuated (less blunt than in 2h. simples). 
In the structure of the wings it stands exactly on the same level 
as the foregoing species. 
Colour (one skin; adult; teeth almost quite unworn).—Fur 
of the upper side uniform dull “ mars-brown”; base of hairs 
slightly lighter ; under side very much of the same colour as the 
upper side, but with a slight tinge of “ drab.” 
Skull. Postnasal depression and supraorbital crests as in 
Rh. simplex. Nasal swellings very narrow (4°9 mm.). Chief 
character (compared with the three foregoing species): the very 
narrow brain-case (7 mm.). 
Dentition. p, quite external, and cingula of p,and p, in contact 
(a sufficiently large series will presumably show some vacillation 
in the position of p,). p®? in the tooth-row ; its cusp very small. 
Measurements. On p. 84. 
Type. Ad. (skin). Goram Island. Collected by Dr. A. R. 
Wallace. Brit. Mus. no. 61.12.11.10. 
Remarks. This species is readily distinguished from Lh. celebensis 
and Lh. borneensis by the different shape of the facial portion of 
the skull. 
Dobson regarded the specimen here described, together with 
two others from N. Celebes (Menado), as a variety (“@”) of 
Rh. megaphyllus, characterised chiefly by having “‘the summit of 
the vertical process of the sella broadly rounded off, much 
broader than the base.” But, firstly, it should be remembered 
that a sella, much broader at summit than at base, would be 
exactly the reverse of what is found in megaphyllus; it would 
even be unique in the whole genus. Secondly, on resoftening 
the nose-leaves I found the sella, in all the three specimens, quite 
of the same general shape as in Ah. borneensis, i.e. practically
