The sliape of tlie peiiis of some Antelopes. 



The general structure of the male organs of the Artio- 

 dactyla is now to great extent known chiefly throiigh the 

 investigations of Garrod, Gerhardt and the present author. 

 There is, however, a great number of genera of Antelopes 

 which are still unknown in this respect. Desiring to fill that 

 gap in our knowledge I asked my friend D:r I. Trägårdh, 

 when he some years ago went to Natal and the Zulii land, 

 to collect material of Antelopes to elucidate these questions. 

 He kindly did so, and I am thus able to present descrip- 

 tions of the male organ of several species of Antelopes be- 

 longing to different genera and to three different subfamilies 

 according to the arrangement used in the »Book of Ante- 

 lopes». By this a valuable addition to the knowledge about 

 the organ in question is received, and it is made probable 

 that the difference between the »ovine» and »bovine» types 

 is not fundamental but that the latter is a result of a reduc- 

 tion which has taken place independently in different groups.
