The probable affinities and phylogeny of the principal forms of 
the Rh. lepidws group are expressed in the subjoined diagram

IIL. Tart RarwoLorxus uipAs GROUP. 
Diagnosis. Cochlee large, making the basioccipital, between 
them, extremely narrow (linear). Posterior connecting process 
very low and rounded off. 
26. RuINOLOPHUS MiDAS, sp. n. (Plate IV. fig. 204, 6, ¢, 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 easily overlooked) constriction 
at the middle; summit rounded (breadth 1°6imm.). Connecting 
process very low, and broadly rounded off. Lancet long (4 min.) 
and cuneate. One mental groove only. 
Kars 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 mor, considerably 
structure, and the mental grooves (Andersen, Ann. & Mag. Nat. Hist. (7) xvi. Sept. 
1905, pp. 291-92). Rh. maclaudi is an Ethiopian representative of the Rh. philip- 
pinensis group, but on a considerably higher stage of development in the same 
respects as the species just named (Id., tom. cit. Aug. 1905, pp. 254-55). 
This completes the account, showing that all the Ethiopian Rhinolophi, without 
exception, are of Oriental origin.
