A SUPPLEMENTARY MONOGEAPH 



OF THE 



CRETACEOUS ENTOMOSTRACA OF ENGLAND AND IRELAND. 



I. OYPRIDID^. 

 I. Paractpkis, G. 0. Sars, 1865. 



Among the marine members of the Cyprididse, is Paracijpris, described by G. S. 

 Brady in the ' Trans. Linn. Soc.,' vol. xxvi, 1868, p. 377. The general shape of 

 the carapace, which is long, narrow, and somewhat curved, relatively high and 

 thick in the anterior third, and tapering obliquely to the acute posterior extremity, 

 is our guide in referring the following specimens to this genus. 



1. Paracypris gracilis {Bosqiiet). Plate II, fig. 50. 



Baiedia siliqita, var. ft, Jones. Monogr. Entom. Cret,, 1849, p. 25, pi. v, fig. 



16 h. 

 — aecuata (Milnster), var. geacilis, Bosquet. Mem. Commiss. Carte 



geol. Neerlaade, vol. ii, 1854, 

 p. 70, pi. V, fig. 4. 

 Paeacypeis ? GEACILIS, Joiies. Geol. Mag., 1870, pp. 75, 77. 



Size. — Length 77, height '22 mm. 



The original fig. 16 h (PI. II, fig. 50) represents a somewhat deformed or 

 injured individual, probably identical with the delicate, narrow, elongate, tapering 

 form, which M. Bosquet regarded as a thin variety of Mlinster's Gythere arcnata.^ 

 The differences, however, are suflBcient to allow of specific distinction among 

 Ostracoda.
