of the Asiatic Chiroptera, p. T7, 1876), it must be a very tiger among 

 bats, able, from its superior size, great development of the volar membranes, 

 and powerful canine teeth, to prey not only upon every known species of 

 Microchiroptera inhabiting the Australian region, but also, probably, upon 

 every other species of the whole sub-order, for one species only — Phyllo- 

 rhina commersonii. Geoff. ( = EJi. gigas. Wgnr) — exceeds it in the length 

 of the forearm, yet in that species the forearm is disproportionately long, 

 and in general measurements Megaderma gigas has greatly the superiority 

 —it is therefore also the largest known species of Microchiroptera. 



The position of this species in the genus appears to be between M. 

 spasma and M. cor., but more closely related to the latter, with which it 

 agrees in the presence of post-orbital processes (though comparatively 

 very short), and in the absence of the minute first upper premolar. 



To the great liberality of Prof. Ehlers, of the Grottingen Museum, I 

 owe the opportunity which has been afforded me of examining and 

 desci'ibing the type of this most interesting species. 



Megaderma cor. Ptrs. 

 Rab. Abyssinia 5 Malindi ; Mombasa. 



Megaderma frons, Geoff. 



To the localities of this species add Kau, River Osi, Bast Africa 

 (Fischer and Peters). Heuglin (op. cit.) notices this species from the 

 Upper Nile, south of the fifteenth parallel of latitude, and remarks that it 

 occurs along the banks of streams, and in thick jungle in the tops of 

 trees ; that it sees well by day, and occasionally flies about in fall sun- 

 shine. This agrees sufficiently closely with Capt. Speke's account of the 

 same species quoted by me in ' Catal. Chiropt. Brit. Mus.' p. 160. 



Nycltris liispida, Schreb. 



To the localities of this species add Kitui, Pokomo-land (Fischer and 

 Peters). 



Xijcteris grandis, Ptrs. 



The occurrence of two perfectly adult specimens of this species in Dr. 

 Robb's Zanzibar Collection, not only adds a new locality, but their size 

 shows that the type in the Leyden Museum, and the larger specimen in 

 the British Museum, are but immature individuals. The following are 

 the measurements of an adult male : — 



Length: head and body, 3" inches, tail 3", head 1"-16, ear l"-35, 

 tragus 0"-3 x 0"-l, forearm 2"-5, thumb 0"-65, third finger (metacarp. 

 1''''8, 1st ph. l"-2, 2nd ph. l"-5), fifth finger (metacarp. 2"-2, 1st ph. 

 0"7, 2nd ph. 0"-65), tibia l"-2, calcaneum l"-0, foot 0"-55. 



The second lower premolar in these specimens is much smaller pro- 

 portionately, evidently owing to the growth of the adjoining teeth, and is 

 crushed in between the first premolar and first molar. 



Nycteris mthiopica, Dobson. 



The tragus is incorrectly given ( ' Oatal. Chiropt. B. M.,' p. 165) as 

 narrower than that of N. javanica. It is really broader and altogether 

 larger, as the well-preserved specimens in Dr. Robb's collection show, the 

 mistake in my original description having arisen from the contracted con-
