adult males, 3 to an adult female in young, 4 to a youngish male 

 with the wing-joints imperfectly ossified, all of them being preserved 

 in spirit in the British Museum ; and column 5 to a specimen in skin 

 in the same collection, — the whole of them having been collected in 

 Australia by Sir G. Grey, K.C.B., and presented to the National 

 Collection. The dimensions in column 6 have been taken from the 

 specimen of M. blepotis mentioned in Dr. Gray's ' Catalogue of 

 the Mammalia of the British Museum,' as having been received from 

 the Leyden Museum, its country being Timor. It is probable, 

 therefore, that this may have Ween mistaken by M. Temminck for 

 the female of that species. Be this as it may, the specimen in 

 question is certainly a male, and the perfectly ossified condition of 

 the wing-joints indicates that it is adult.

Expanse of wings 



The name under which I have described this species was given 

 under the impression that it was exclusively a native of Australia. 

 It was not until after I had arranged and named the specimens in 

 the British Museum and in some other collections, that I found it 

 to be an inhabitant of Timor (and probably other islands of the In- 

 dian Archipelago) as well as of Australia, and that the name of 

 australis was not strictly appropriate. But to avoid the confusion 

 which might possibly arise from a change of name, I have thought 

 it desirable that it should remain unaltered. 



The two species following I am unable to give as complete an ac- 

 count of as I could wish. 



The first is exhibited in the Leyden Museum with the name of Vesp. 

 tibialis affixed, but I am not aware that any description has appeared. 

 In that collection are four specimens, all from Amboyna. A single 

 specimen in my own collection, received also from Amboyna by 

 MM. Verreaux, although in a somewhat mutilated condition, will 

 nevertheless furnish a sufficiently complete description by which to 

 recognize the species, if species it really is. 



In general appearance it closely resembles M. blepotis, but is a 

 trifle smaller, and moreover appears to differ remarkably in all the 

 specimens, in having the extremity of the tibia perfectly free for 

 nearly a third of its length. The wing-membranes do not extend 

 beyond two-thirds of the length of the tibia, and the os calcis ad-
