upper premolar, and the dental formula therefore agrees with that of 

 M. frons. 



The rudimentary premaxillse resemble more closely those of the 

 Rhinolophidse than those of any other species of Megaderma. As in 

 that family, they project considerably beyond the line of the canines, 

 from which they are also separated by a diastema on either side ; and 

 two small depressions in the gum may be seen, which appear to be the 

 empty sockets of a pair of rudimentary teeth, occupying precisely the 

 same relative position as in the species of Rhinolophidse, an additional 

 indication of the close affinity of the Nycteridse to that family. 



In the skull, as I have generally observed in the larger species of 

 each genus, the sagittal crest is well developed, and the pair of ridges 

 into which it divides in front are so strongly marked as to cause the 

 frontal bones between them to appear considerably hollowed ; these 

 ridges terminate on each side in a blunt but well-marked postorbital 

 process, which, however, as in M. spasma, is not perforated by a 

 foramen (Plate XLVI. fig. b). In this respect, therefore, the skull 

 agrees with that of M. spasma, which inhabits part of the same 

 zoological region, though apparently agreeing more closely with M. 

 frons and M. cor in the flattened and expanded frontals and in the 

 absence of a minute upper premolar.

This specimen, sent by Dr. Schuette to the Gottingen Museum, is 

 the same as that mentioned by Mr. G. Kreift, CM Z.S., in a com- 

 munication read before the Society in May 18/9 (see P. Z. S. 1879, 

 p. 386). It was accompanied by the following note on the colour 

 of its iur and integuments : — 



" Flughiiute, Ohren, und Nasenblatt fleischfarbig. AUe Haare 

 auf diesen Theilen weiss, auf dem Riicken sind die Haare bleifarbig. 

 Die Haut welche die Ohren verbindet ist tief blutroth." 



Rhinolophus petersi, Dobson. 



An adult male from Sumatra, thus indicating the Oriental as the 

 zoological region to which this species (of which the habitat was 

 unknown) belongs. The only difference observable between this and 

 the type specimen is that the free extremity of the tail does not pro- 

 ject so far as in the latter. 



Vesperugo maurus, Blasius. 



Two specimens in the collection must, I believe, be referred to 

 this species, though they are said to have been received from localities 

 many thousands of miles apart. One from Tuscany was sent to the
