Nomenclature of the Foraminifera. 203 



8. Cristellaria Cassis, F.ScM. sp. Diet. xi. p. 614, xxxii. p. 188. 

 See Ann. Nat. Hist. ser. 3. v. p. 115. 



9. Cristellaria Isevis, Defrance, 1818. Diet. xi. p. 614. This 

 is a subvariety of C. Cassis, having no septal ribs, and a smaller 

 umbonal knob. Defrance does not insist on its being specifically 

 distinct. 



10. Cristellaria producta, Lam. Diet. xi. p. 614. Under this 

 name Lamarck placed two of Fichtel and MolFs varieties (y8 and 

 7) of Cristellaria Cassis; fossil, from Coroncina, Italy. 



11. Dactylopore. Diet. xii. p. 443. Dactylopora cylindracea, 

 Lamarck; Atlas, Zooph. pi. 47. f. 4, pi. 51. f. 6 ; Blainv. Actinol. 

 pi. 73. f. 4, pi. 76. f. 6. Defrance obtained his specimens from 

 the " Calcaire coquillier " of Grignon, near Versailles, and the 

 sand of Pontoise. In the Ann. Nat. Hist. ser. 3. v. pp. 20-27, 

 we described several varieties of Dactylopora, recent and fossil : 

 these descriptions have since been revised and illustrated in 

 Dr. Carpenter's ' Introduction,' pp. 137-137, pi. 10. The va- 

 rieties now adopted are D. Eruca, D. Annulus, D. digitata, D. 

 clypeina [Clypeina marginoporella, Michelin; Dactylopora mar- 

 ginoporella, P. & J. 1860), D. reticulata (Larvaria reticulata, 

 Defrance), D. glandulosa [Prattia glandulosa, D'Archiac), and 

 D. cylindracea, Lamarck. 



The microscopic fossils (from Podolia and Volhynia) figured 

 and described by A. Zborezewski in the ' Nouv. Mem. Soc. Nat. 

 Moscou,' 1834, p. 308, pi. 36. f. 1-3, as Cellulina Eichwaldii, 

 C. Besseri, and C. Puschii, are probably Dactylopora. Accom- 

 panying these, Polymorjjhina lactea, var. tuhulosa, is figured both 

 as Raphulina Humboldtii (p. 311, pi. 38. f. 1 a) and as Apiopterina 

 D'Orbignii (f. 2 a). Montfort's odd figure of his Lagenula is 

 here also referred to Apiopterina; and an obscure two-celled 

 form is figured and described as Lyrina Fischeri. 



The little annular Foraminifer from the "Sables IV''^* de 

 Grignon," described by A. Zborezewski, under the name of Dac- 

 tylina Fischeri, in 1843 (Bulletin de la Soc. Imp. des Naturalistes 

 de Moscou, xvi. p. 363), appears to be the same as Dactylopora 

 Annulus. Zukowa in Podolia is also given as a locality, with a 

 note of interrogation. The woodcut illustrating D. Fischeri is 

 a rough diagram, but characteristic. A figure of what seems to 

 be a Gyrogonite accompanies the woodcut above mentioned, and 

 is named " Spirostegina ;" but no description follows. The 

 author also mentions some others of his species of Foraminifera 

 under the names "Baphulina," "Cepiopterina," and "Pnylo- 

 morphina" (p. 364). 



12. Discorbites Pedemontanus, De/r. 1819. Diet. xiii. p. 347. 

 Indeterminable from the description given — " Orbicular, discoidal; 

 spire entirely visible on one side only ; chambers smaller and
