* " Cornu .... Gazelloe recticornis, quam hodie sola .... 

 Africa alit." Although this has been quoted as Gazella recticornis 

 by Erxleben, and also by Sclater and Thomas, it does not appear 

 to have been intended as a technical name, any more than does 

 " Gazella: .... Indicce" in a later passage.
