Show 1905.] OF THE GENUS RHINOLOPHUS. 141 The skull is markedly smaller, the nasal swellings a trifle narrower, the teeth slightly smaller. Distribution. 32 specimens examined. As it is of some interest to have the range of this hitherto overlooked form exactly determined, I subjoin a list of the localities from which I have seen examples, together with measurements of the forearm; it might perhaps lead to further investigation :- Keren (1, the type *): forearm 36'3. Sennar(l): 36'5. Cyprus (6): 34-7-37-7. Smyrna (1): 37-5. Malta (8): 36-37. Middle Italy (Ostia 2): 35-7-36-8. Corsica (1): 37-7. Haute Savoie and Geneva (2): 37'7-38. Balearic Islands (7): 36-2-37'6. Seville f (1): 37-7. Morocco (Tangiers 1): 37-7. Portugal (Cintra 1): 36-2. Summary of Distribution :-The Mediterranean Subregion, southeastwards to Sennar and Keren. Be it noted : there is no record from Egypt (and, very likely, it does not occur there : cf. remarks on p. 143). Remarks. In the whole series of Rh. hipposiderus examined (apart from the British specimens, of course) I have not found any individual which I could not easily refer either to the southern or the northern form. I have some reason to believe that in certain border districts (e. g. S.W. Switzerland ; perhaps also Cyprus) the two forms occur together, perhaps side by side, but intermediate examples I have never seen. They will probably be found. 27 b.

The type is a young, but apparently fullgrown, individual. A ll other examples of hipposiderus, of all races, of which I give the measurements, are fully adult (distal epiphyses of metacarpals ossified). f As I have seen only one example from Spain, I may mention that of the whole series examined by Cabrera Latorre, for his " Quiropteros de Espana," no Spanish specimen had the forearm more than 37'5 mm. (Mem. Soc. Espan. Hist. Nat. ii. (1904) p. 252). I am unacquainted with the Rh. phasma (allied to hipposiderus) described by Cabrera in the same paper. |
