14. M. J. Bosquet also found some specimens of a Tertiary 

 Cypridinid in the Eocene beds of France, and he described it 

 as a Cyprella, with illustrations. '' Descript. Entomost. foss. 

 Terr. Tert. France et Belgique " (Mem. cour. Acad. Roy. 

 Belgique, 1852, p. 132, pi. vi. figs. 14 a, J, c, c?). This is 

 (he neatly punctate, oval Cypridina Eduardsiana [Cyprella^ 

 Bosquet), he. cit. Length 1'2, height "75, and thickness 

 •7 millim. It was obtained from the " Sables Moyens " of 

 Ver (Oise) and of Tancrou (Seine-et-Marne), also from the 

 " Calcaire Grossier " of Chateaurouge, of Parnes and Chau- 

 mont (Oise), and of Orme and Grignon (Seine-et-Oise) .

15. While sorting and examining, several years ago, some 

 material of a friable calcareous deposit of Eocene age from 

 Orglandes, Dep. Manche_, France, procured by Sir C Lyell 

 in l.Solj the writer met with a broken valve of a symmetrical 

 little Cypridina of the not unusual broad oval shape, with u 

 small neat hood and notch. Surface smooth, but bearing a 

 rather obscure radiate muscle-mark. The fragment (tig. la) 

 is 6 millim. long, the smaller moiety of a valve probably 

 9 millim. long ; the height of the valve is G millim. and the 

 thickness of the carapace was 5 millim., the valve being 

 2^ millim. in depth or thickness. (PI. XVII. figs. 1 a, J, c.)
