12 CRETACEOUS ENTOMOSTRACA. 



The edge view (fig. 28) is elongate and compressed obovate, being blunter 

 in front than behind ; the end view (fig. 29) is acute-ovate. 



Localit I/. —One specimen only, from the Detritus of Charing, Kent. 



The specimens referred to in the ' Monogr.,' 1849, p. 13, as from the Upper 

 Oolite, and as somewhat resembling this species, are probably what are now known 

 as Cypris Furhed-ensis, Forbes, ' Quart. Journ. Geol. Soc.,' vol. xli, 1885, p. 347, 

 pi. ix, figs. 3 and 5, with Candona Bononiensis, Jones, ibid., p. 348, pi. ix, fig. 7.

 belongs to Bythocypris silicula ; 18 f, f to Fon- 

 tocypris Bosquetiana) . Also part of Bairdia Har- 

 risiana, Jones, ibid., p. 25, pi. vi, fig. 17 f.

Fig. 56. Length -861 ; height '38 mm. 



Fig. 63. „ -72 ; ,, '33 (?) ; thickness -33 mm. 



The left valve (fig. 56) long-obovate, moderately arched on the back, with 

 inturned edge, ventral margin straight, also with an inflexed edge (thus 

 adapted to overlap the other valve above and below) ; obliquely rounded in front, 

 obtuse behind. The right valve^ (former figs. 18 e, e') narrower than the other, 

 slightly incurved ventrally. Valves united have an edge view long-acute-oval 

 (fig. 61) ; end view oval (fig. 62). 



This fabiform Ostracod was too readily referred in 1849 to von Miinster's 

 vaguely described species ; and neither Isevigata, Rom., nor attenuata, Reuss (both 

 mentioned as synonyms at p. 26) corresponds with it, though supported by Reuss in 

 the ' Elbthalgeb.,' &c., ii, p. 150; for it is much too obovate and too blunt poste- 

 riorly for either of the forms figured by Reuss, op. cit., pi. xxviii, figs. 1 — 3. Figs. 

 17/ (fig. 56) and 18 e are much too nearly obovate for the figs. 1 — 3 above men- 

 tioned; but they approach fig. 11 in pi. xxvi, op. cit., one of the forms of Bairdia 

 modesta, Reuss. There are difi'erences, however, even here. 



Named after the late well-known palaeontologist of Prague and Vienna, who 

 worked so long and ardently at the elucidation of the fossil Ostracoda and other 

 Microzoa. 



Localities. — From the GhalJc of Charlton, Kent (fig. 56) ; the Detritus at 

 Charing, Kent (fig. 63) ; and the Gault of Folkestone (figs. 61 and 62). 



^ Fig. 63 (fig. 18 c) having been drawn obliquely does not show the true shape like fig. 56
