A few specimens, all small and somewhat starved except at Stn. 23, where a fair- 

 sized typical individual was found. 



235. Cristellaria rotulata (Lamarck). 



Lenticuliles rotulata, Lamarck, 1804, AM. vol. v. p. 188. No. 3; vol. viii. (1806) pi. lxii. fig. 11. 

 Cristellaria rotulata, Brady, 1884, FC. p. 547, pi. lxix. fig. 13 a, b. 



19 Stations. 



Generally distributed and often frequent, but all the specimens are small except at 

 Stns. 2, 10, 20, and 23. 



236. Cristellaria cultrata (Montfort). 



Robulus cultratus, Montfort, 1808-10, CS. vol. i. p. 214, 54e genre. 

 Cristellaria cultrata, Brady, 1884, FC. p. 550, pi. lxx. figs. 4-8. 



7 Stations. 



Sparingly distributed and never very frequent, excepting at Stns. 2 and 20. At these 

 Stns. well-grown individuals occur, but the marginal carina is everywhere very narrow. 



237. Cristellaria variabilis, Reuss. 



Cristellaria variabilis, Reuss, 1849-50, FOT. p. 369, pi. xlvi. (i.) figs. 15, 16.

 One small, but typical, specimen. 



Subfamily Polymorphinin^e.

Brady, 1884, FC. p. 560, pi. lxxi. fig. 13. 



1 Station. 



One specimen resembling Reuss's earlier (1851) figure, which is less compressed than 

 his later (1855) figure. The question of the advisability of separating this form from 

 P. lactea is very doubtful. It has probably been often recorded under that name.
