Milne-Edwards divided his Pranisiens into two tribes, Pranisiens and Anceeus. 

 White, who at first included Praniza and Anceus in a single family, subsequently 

 allotted each genus to a separate fomily. The great distinction belongs to M. Eugene 

 Hesse of having demonstrated that forms apparently so widely apart, that they could 

 by good naturalists be placed in separate genera, tribes, or families, were really females 

 and males of the same species. It is also memorable that Leaoli in 1813 had already 

 deelare<l his suspicion that this might be the Ciise, while M. Hesse's not readily 

 accepted announcement of the fact was not made to the Acadtsmie des Sciences in 

 Paris until November, 1855.
