XLVI. — ^1 nev^ Genus of J3ats allied to Nyctophilu.s. 

 By Oldfield Thomas. 



(Published by permission of the Trustees of tlie British Museum.) 



On examining- the various bats in the Museum collection 

 assigned to JSijctopliilus, I find that one of them, from New 

 Guinea, is a new species so ditlerent Irom the other members 

 ot the group as to warrant the formation for it of a special 

 genus, which may be called 



Phaeotis, gen. nov. {Vespertilionidce). 



Nearly allied to JVi/ctopIiilus, but the skull of different 

 shai)e and the palate much shortened. 



External characters essentially as in Nijcloplulus, but the 

 ear and nasal membranes more developed. 



Nose-leaves larger than in that genus, the anterior one 

 broad, high, its upper margin evenly convex, without 

 median depression or notch ; no vertical ridge between the 

 nostrils ; posterior projection not a mere thickening of the 

 skin, but a more or less definite leaf, as high as, tliongh 

 narrower than, the anterior leaf ; concavities in front of and 

 behind it deep, their deepest part naked and peculiarly 

 wrinkled. Ears very large, thin, leafy, connected across the 

 forehead by a high band. Tragus long, narrowed terminally, 

 the peculiar thickened lobe on the back placed in the middle 

 instead of on the outer edge, and extending outwards nearly 

 to each side. 



Skull quite different in shape from that of Nyctophilus. 

 Brain-case large, smooth, and rounded, without crests; 

 muzzle very short, nasal notch deep, its posterior end behind 

 the level of the anfceorbital foramina. Jnterorbital region 

 very broad, its edges smoothly rounded. Bulla3 of medium 

 size, their length about o"5 or 3 6 mm. Anterior palatal 

 notch deep, ending level with the hinder edge of the pre- 

 molar ; ])05terior palate shortened, ending not far behind the
