1905.] OP THE GENUS RHIN-OLOPHUS. 129 



(three) ; in none, completely in contact, p^ in row ; a well- 

 developed cusp, pointing inwards. Upper canine and p* widely 

 separated ; in one sknll there is a small interspace between p" and 

 p' (the former place of p^). 



JDistribution. Japan proper. 



Remarks. In general size, as well as in the skull and dentition, 

 the Tsu-sima Bat agrees with the typical form ; but the colour is 

 that of Rh. c, pumilus *. 



20. Rhinolophus gracilis, sp. n. (Plate TV. fig. 18 a, h, c.) 

 Rhinoloplixis minor (partim, nee Horsf.) Dobson, ut supra. 

 Diagnosis. Skull : the minor-tj^e. Sella parallel-margined ; 



tail extremely short. Yery small: forearm 36"2 mm. 



Details. This is an aberrant species of the minor-tj'^e. The 

 connecting process is quite of the same shape as in the foregoing 

 species (very different from that of subbadiics). 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 with a tendency towards 

 a subacute shape, as in the foi-egoing forms of this group ; length 

 of sella 2"8 mm. ; width at base 1"8 mm., at summit l'7mm. 

 The lancet is, considering the small size of the Bat, remarkably 

 long (4 mm.), with the lateral margins almost straightly converging 

 towards the tip ; it recalls the lancet of Rh. inidas and hippo- 

 siderus (with which species Rh. 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 Rh. lepidus. 



Skull. Quite of the m.inor-tj]iQ. 



Dentition (one skull), p^ external, p^ and p^ distinctly separated, 

 p^ in row ; cusp extremely minute (unworn).

* I have examined a paratype of Gerrit S. Miller's Bli. minutus (Proc. Wash. 

 Acad. Sci. 1900, p. 235), the type of which is from the Anamhas Islands. It is an 

 offshoot of the «7j«or-type, but undoubtedly a distinct species, differing from 

 Rh. minor (from Darjeeliiig) in having the brain-case decidedly higher in front, 

 giving the skull, in side view, a very characteristic outline. The name "miniitns" 

 is, however, preoccupied by Montagu's " Vesfertilio minutiis" which is the Britif-li 

 form of Mh. hipj>osiderus. Mr. Miller will rename the Anambas species.
