88 AETHEOPOUA. 



Hippidae are referred by Glaus to Macrura, the remainder to the 

 Brachyura ; Porcellanidas, Lithodidae, Dromiidse, and Dorippidre 

 forming his group "Notopoda;" while Baninidae are placed, 

 together with Leucosiidee and Calappidas in the Oxystomata. 

 Schmarda includes in his Anomura only the families represented 

 by Hippa, Litkodes, and Pagurus. Here Milne-Edwards is pro- 

 visionally followed, except that Dromiidae change places with 

 Dorippidae.

Schmarda adopts Milne-Edwards's four " families,'* with the 

 addition of Dromiidge. Claus has nineteen ; excluding the Ano- 

 inurous families, the principal difference in the following list 

 is that he separates Eriphia from the Cancriclse, and unites 

 Inachidae to the Maiidse. The last four families have been re- 

 cently worked out by Miers, whose arrangement, reversing the 

 order, is here followed. 



Leueosiida. Calappida. 



Dromia. Ebalia. Thealia. 



Dynomene. Philyra. Calappa. 



Oreophorus. Matuta.
