108 OLDFIELD THOMAS 



it is evident that the present species, of which the male and 

 female before me are practically identical, should also have a 

 name to designate its place in this series of similar species. 

 In Dr. Modigliani's paper on Pulo Nias, an excellent account 

 is given of the Pt. nicobaricus he found there, and he is to be 

 congratulated on his discovery of the present interesting form.

It appears to me very doubtful whether this and H. cervmns, 

 Gould, are really distinguishable species, the differences mentioned 

 by Dobson seeming to disappear on the examination of a larger 

 series. 



8. Hipposiderus bicolor, Temm. 

 a-b. 2 <^. Bua-Bua. 



These specimens are rather larger than usual, their forearms 

 measuring respectively 47 and 45 mm. 



0. Vesperugo imbricatus, Horsf. 



a. 9. Kifii-juc, May 1891. 



Forearm 32 mm. 



This specimen is of considerable interest in connection with 

 Dr. Modigliani's remarks on the relationship of W macrolh to 

 v. imbricatus ('), and also owing to the fact that I am now able 

 to make a direct comparison of a properly preserved spirit spe- 

 cimen with Horsfield actual type, this latter being in so hope- 

 less a state of decay that the present is likely to be almost or 

 quite the last examination which it will bear. This comparison
