The probable affinities and phylogeny of the principal forms of 

 the Rh. lejndifjS group are expressed in the subjoined diagram

III. The Rhjnolophus midas Group. 



Diagnosis. Cochleae large, making the basioccipital, between 

 them, extremely narrow (linear). Posterior connecting process 

 very low and rounded off. 



26. Rhinolophus midas, sp. n. (Plate IV. fig. 20 «, h, c, d.) 



Diagnosis. Sella almost deltoid, summit rounded. Forearm 

 37"7 mm. 



Details. Horse- shoe as broad as the upper lip; no "tooth" on 

 the sides of the median notch ; no crenulation of the border. 

 Lateral margins of sella converging from base to tip ; breadth 

 at base (2' 3 mm.) much more than half the vertical height of the 

 sella (3* 5 mm.) ; a very slight (rather easil}^ overlooked) constriction 

 at the middle; summit rounded (breadth 1*6 mm.). Connecting- 

 process very low, and broadly rounded off. Lancet long (4 mm.) 

 and cuneate. One mental groove only. 



Ears a little longer than in minor, outer margin immediately 

 below the tip somewhat more emarginate ; tip more distinctly 

 pointed. 



Wing-structure, compared with that of minor, considerably 



structure, and tlio mental grooves (Andersen, Ann. & Mag. Kat. Hist. (7) xvi. Sept. 

 1905, pp. 291-92). Bli. maclaiuli is an Ethiopian representative of the Bh. pMlip- 

 pinensis group, but on a considerably higher stage of development in the same 

 respects as the species just named {Id., torn. cit. Aug. 1905, pp. 254-55). 



This completes the account, showing that all the Ethiopian Bhinolophi, without 

 exception, are of Oriental origin.
