386 Mr. K. Andersen on the Geographical Races 



kind (for, inasmucli as the difference between minimus 

 and hipposiderus is a well-marked but small difference of 

 size^ nobody would, of course, be able to tell whether a young 

 individual, obtained in a region where we have all reason to 

 believe that hath forms occur, is referable to the one rather 

 than to the other form), — I shall now, in the interests of the 

 subject, challenge his conclusions and prove, by means of 

 indisputable figures and facts, that M. Mottaz's result, strange 

 as it is, is totally wrong as well. Strictly speaking I cannot, 

 of course, prove anything about the very specimens examined 

 by M. Mottaz, and which I have not seen, but this is also not 

 necessary ; if only I succeed in proving, on the basis of the 

 large British Museum series, the validity of the characters of 

 minimus and hipposiderus, and their perfect independence of 

 the sex of the individuals, then M. Mottaz will get nobody to 

 believe that what in southern as compared with northern 

 specimens of the Lesser Horseshoe is a well-marked racial 

 difference, is in Switzerland transformed into a sexual 

 difference. 



Subjoined I give the locality, sex, and length of forearm of 

 all the full-grown examples of minimus and hijyposiderus 

 which I have had the opportunity of examining up to this 

 moment. Be it noted that the measurement of the forearm 

 has been taken from the most backward projecting point of 

 the forearm to the front curve of the carpus (wing folded). 

 All the measurements are of perfectly adult specimens, with 

 one exception, mentioned below. 



Bh. h, minimus. 



Erytlirea: Keren. — One male, young adult, tj^pe of Rh. minimus, 

 Heuglin : 36'3 mm. (The not quite consolidated condition of the 

 fiuger-j oints of this individual proves it to be slightly immature ; 

 it is, however, in all probability full-grown ; I give the measure- 

 ment here only because this example is the type specimen.)
