133 Mr. 0. Thomas on Emballonura, 



Thus the mesopterygoid fossa is markedly shorter, the 

 distatice from tlie jjalation to tlie saddle-back convexity at 

 its hinder end I'l mm., as compared with i"6 ram. ; it does 

 not open quite so far forward, and the openings into the 

 nasal chamber are not so hirge and the ethmoid bones are 

 consequently less exposed. In the basial fossa, the median 

 septum, which in nueki is represented by a broad low 

 elevation, slightly grooved mesially and only running half 

 across the fossa, consists of two low but quite distinct ridges, 

 running back, slightly divergent, quite to the back of the 

 fossa. In all other species, the median septum, if present, 

 is truly median and without tendency to split into two. As 

 in E. meehi, the whole fossa is rather shallow, narrow, with- 

 out lateral septa or antero-lateral extensions.

Like as meeki and eluvium are in all other respects, the 

 skull-differences described above are constant through three 

 specimens of one and five of the other. But an example 

 from, the Owen Stanley Range, New Guinea, is somewhat 

 intermediate in character as in locality, and I therefore only 

 distinguish the new form as a subspecies. 



Emballonura beccarii, Pet. & Doria. 

 Judging by a drawing of the tragus of the type, kindly 

 sent me by Dr. Gestro, I am inclined to tliiidi this will prove 

 to be a synonym of E. rufrayana, Dobs., a si)ecies described 

 after the publication of Dobson^s Catalogue, and not men- 

 tioned in Peters and Doria's description. . The typical 

 localities of the two are quite near each other. 



Emballonura stresemanni, Thos. 

 Of this species the Museum contains, besides the typical 

 series, a number of specimens collected by the late Mr. W. 

 Stalker in Ceram, during the B.O.U. New Guinea expedition. 

 It has the same broad oblong tragus as E. raffrayana, Dobs., 

 as is also the case with the following.
