214. Cristellaria italica, (Def ranee.) 



Saracenaria italica, Defrance, 1824. Diet. Sci. Nat. XXXIL 

 p. 177, vol. XLVII, p. 344, Atlas Conch- pi. XIII, fig-. 6.. 



Cristellaria italica, Brady, 1884, Chall. Rep., p. 544, pL 

 LXVIII, figs. 17, 18, 20-23. 



Frequent and found in all Gatherings. The specimens do. 

 not usually attain large dimensions. 



215. Cristellaria latifrons, Brady. 



Cristellaria latifrons, Brady, 1884, Chall. Rep., vol. IX, p. 544,. 



pi. LXVIII, fig. 19; and pi. CXIII, fig. 11a, b. 

 C. latifrons, Chapman, 1894, Journ. Roy. Mic. Soc, p. 652, 



pi. X, fig. 8a, 5. 



Very rare, single specimens found in Gatherings No. 1 

 and 2 (1893). These small examples resemble Brady s drawing" 

 on plate LXVIII, of the "Challenger" monograph, rather than 

 that of plate CXIII., in that the angles of tiie shell are acute 

 but not carinate. The tests are also more elongate than in 

 Brady's last figure. 



(The specimens are far from satisfactory, as the edges do 1 

 not possess the sharp subcarinate margin which is typical of 

 Brady's species. We should have been inclined to refer them 

 to C. crepidula.) 



216. Cristellaria gibba, d'Orbigny. 



Cristellaria gibba, d'Orbigny, 1826, Ann. Sci. Nat., vol. VIL

Extremely rare. A single typical example found in Gather-

217. Cristellaria crassa, d'Orbigny. 



Cristellaria crassa, d'Orbigny, 1846, Foram. Foss. Vienne, p-

fig. la, b. 



Rather rare and sparsely distributed, occurring both at the 

 top and bottom of the Marl and also in several intermediate- 

 Gatherings. The specimens are typical and robust.
