The présent research is the natural continuation of that of Professor 

 Ide on the Edriophthalmia. We hâve endeavoured to treat the group of the 

 Schizopoda, as he has done those of the Isopoda and Amphipoda. In order 

 to facilitate the study of the tv^o Works, we hâve preserved as far as possible 

 the référence letters of Professor Ide. 



Much has already been written on the Decapoda and the Edriophthal- 

 mia, but the comparative anatomy of the digestive System of the Crustacëâ 

 in gênerai has yet to be done. To make a gênerai comparison, it is absolu- 

 tely necessary to make a detailed study of ail the groups. We hâve no 

 intention of giving a history hère of what has been done in the groups of 

 the Decapoda and Edriophthalmia. It will be found treated at lergth in 

 the memoir of Professor Ide, who was the first to publish a complète study 

 of the digestive system of the Isopoda and the Amphipoda. He has shown 

 what he considers to be homologous pièces in the stomachs of the Decapoda 

 and the Edriophthalmia. 



Years before, Milne-Edwards had made an attempt to compare the 

 stomach pièces in thèse groups from the descriptions given by Lereboul-
