[Eeceived Noyember 15, 1878.] 

 (Plates v., VI.) 



The remarkable and unique characters of the generative organs of 

 HycBna crocuta, accounts of which have formed the subject matter 

 of two previous communications to this Society', suggested the 

 advisability of investigating the general anatomical features of this 

 species with a view to future comparison. In the meantime, as 

 nothing hke a comprehensive or detailed description of the anatomy 

 of the Spotted Hyaena has hitherto been given, and as that of 

 other members of the same genus is incomplete and exists only in a 

 scattered form, we have thought that the record of our observations 

 on this subject might be of use. That it might prove so we have 

 endeavoured to ensure by making our descriptions as complete as 

 ' Watson, Pro,-. Zool. Soc. May 1877, and April 1878.
