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

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

 as a Cyprellay with illustrations. " Descript. Entomost. foss. 

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

 Belgique, 1852, p. 132, pi. vi. figs. 1 4 a, Z>, c, c?) . This is 

 the neatly punctate, oval Cypridina Eda-ardaiana [Cyprella, 

 Bosquet), loc. 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 Chatcaurouge, 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 CJ. Lyell 

 in 1(S51, the writer met with a broken valve of a symmetrical 

 little Cypridina of the not unusual broad oval shaj^e, with a 

 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- 

 s' millim. in depth or thickness. (PI. XVII. figs. 1 a, b^ c.)
