Only one member of the subfamily Neotragince has hither- 

 to been described with regard to its male organ viz. »Nan- 

 notragus» {= Ourehia) nigricaudatus. This was described by 

 Garrod (1) as »a slender, tapering cone, beyond which the 

 urethra, which is free from it for the terminal Vs of an inch, 

 continues straight on for Vs of an inch». The figure com- 

 municated agrees with this description. Although Garrod 

 plainly states that the penis of the species mentioned »does 

 not in the least resemble that of Cephalophus^y (1. c. p. 11), 

 Gbrhardt (4) has probably missunderstood him and figu- 

 res a penis of »Nannotragus» with a long filiform appendage 

 (1. c. p. 153). 



At this occasion I am able to describe the conditions 

 found in two other genera of this subfamily which are not 

 much different from Ourehia in this respect. 



»The Steenbok» (Rhaphicerits campestris) has its penis- 

 end not so strongly tapering as Ourehia. It ends rather

bluntly, and the portion corresponding to the terminal cushion 

 of Ceyhaloplius is not, or hardly thicker than the proximal 

 portion (conf. fig. 3). The urethra is comparatively wide. 

 Its terminal portion is fully detached for about 2 mm. but 

 received in a groove of the penis beyond the tip of which 

 it extends very iittle. 



»Livingstones Antilope» {Nesotragus livingstonianus 

 Kirk)^ is very similar to the Steenbok with regard to the 

 shape of its penis but this organ is somewhat more tapering 

 in Nesotragus and the slightly upturned end of the compa- 

 ratively wide urethra is only detached with its extreme tip 

 (fig. 4). 



The general shape of the penis of these two members of 

 the subfamily Neotragince is thus more similar to the »bovine» 



' Perhaps the subspecies »zuluensis» Thomas 1898, but for the pre- 

 sent purpose this is of Iittle importance.
