1905.] OF THE GENUS RHINOLOPHUS. 129 
(three); in none, completely in contact. p® in row; a well- 
developed cusp, pointing inwards. Upper canine and p' widely 
separated ; in one skull there is a small interspace between p° and 
p’ (the former place of p’). 
Distribution. Japan proper. 
Remarks. In general size, as well as in the skull and dentition, 
the T'su-sima Bat agrees with the typical form; but the colour is 
that of Rh. c. pumilus*. 
20. RHINOLOPHUS GRACILIS, sp.n. (Plate IV. fig. 18 a, }, c.) 
Rhinolophus minor (partim, nec Horsf.) Dobson, ué supra. 
Diagnosis. Skull: the minor-type. Sella parallel-margined ; 
tail extremely short. Very small: forearm 36°2 mm. 
Details. This is an aberrant species of the minor-type. The 
connecting process is quite of the same shape as in the foregoing 
species (very different from that of subbadius). But the sella is 
parallel-margined, as broad at the summit as at the base; by 
means of a lens (probably not without) an exceedingly faint trace 
of a constriction can be observed; the summit of the sella is 
broadly rounded off, as in borneensis, not witha tendency towards 
a subacute shape, as in the foregoing forms of this group; length 
of sella 2°8 mm.; width at base 1:8 mm., at summit 1-7 mm. 
The lancet is, considering the small size of the Bat, remarkably 
fo) 
long (4mm.), with the lateral margins almost straightly converging 
towards the tip; it recalls the lancet of Rh. midas and hippo- 
siderus (with which species &h. gracilis has no very close 
affinity). 
The tail is extremely short (13°5 mm.), shorter than the lower 
leg. Plagiopatagium inserted a trifle above the ankle. 
The colour (a little faded in alcohol) has probably been rather 
like that of 2h. lepidus. 
Skull. Quite of the minor-type. 
Dentition (one skull). p, external. p,and p, distinctly separated. 
p in row; cusp extremely minute (unworn). 
Measurements. On p. 132.

* T have examined a paratype of Gerrit S. Miller’s Rh. minutus (Proc. Wash. 
Acad. Sci. 1900, p. 235), the type of which is from the Anambas Islands. It is an 
offshoot of the minor-type, but undoubtedly a distinct species, differme from 
Rh. minor (trom Darjeeling) in having the brain-case decidedly higher in front, 
giving the skull, in side view, a very characteristic outline. The name “minutus” 
is, however, preoccupied by Montagu’s “ Vespertilio minutus,’ which is the British 
form of Rh. hipposiderus. Mr. Miller will rename the Anambas species.
