Nomenclature of the Foraminifera. 217 



p. 187, xlvi. p. 303 ; Atlas, Couch, pi. 14. f. 3, & pi. 19. f. 1 ; 

 Bl. Malac. p. 391, pi. 6. f. 3, & pi. 10. f. 1. Defrance remarks 

 that both dextral and sinistral shells occur. 



This is a well-developed variety of Discorbina Turbo, D'Orb. 

 See Ann. Nat. Hist. ser. 3. v. p. 294; and Carpenter's 'Intro- 

 duction/ p. 204. 



126. Saraceuaria italica, Defr. 1824. Diet, xxxii. p. 177, 

 xlvii. p. 344; Atlas, Conch, pi. 13. f. 6; Bl. Malac. p. 370, 

 pi. 5. f. 6. Fossil; from Italy: a trihedral Cristellaria. De- 

 france likens it to " un petit grain de sarrasin :" i line to H line 

 in diameter. 



This is found, both recent and fossil, where CristeUarm are 

 abundant, D'Orbigny had this from Rimini in the Adriatic, 

 and recognized it as a Cristellarian form, making it a subgenus 

 of Cristellaria, and illustrating it by his Models, nos. 19 & 85 

 (Ann. Sc. Nat. vii. p. 293). 



127. Siderolina calcytrapoides et Siderolites calcitrapoides, 

 Lam. sp. Diet, xxxii. p. 180, xlix. p. 98; Atlas, Conch, pi. 13. 

 f. 7; Bl. Malac. pi. 5. f. 7. From Maestricht. Calcarina 

 Spengleri, Gmel. sp. See Ann. Nat. Hist. ser. 3. iii. p. 480, & 

 V. p. 291 ; and Carpenter's "^Introduction,' pp. 216-223. 



128. Siderolites Spengleri, Gmel. sp. Diet, xxxii. p. 179; 

 Bl. Malac. p. 373. This is Calcarina Spengleri, Gmel. sp. 



129. Spirolina (et Spirolinites) cylindracea, Z/ffm.* Diet, vol.1, 

 p. 298; Atlas, Conch, pi. 13. f. 1 ; Bl. Malac. pi. 5. fig. 1; and 



130. Spirolina (et Spirolinites) depressa, Lam. Diet. vol. 1. 

 p. 298 ; Atlas, Conch, pi. 13. f. 2; Bl. Malac. pi. 5. f. 2. De- 

 france alludes also to a recent species, apparently identical with 

 Sp. cylindracea, and living in the Mediterranean. He remarks 

 that, in the 'Tabl. Meth. Ceph.' (Ann. Sc. Nat. vii. p. 287), 

 D'Orbigny notices also Spirolina striata, Sp. laevigata, and Sp. 

 Pedum, found fossil near Paris, and groups these with Lituola 

 {Lituolites) nautiloides ; but he thinks the difference in the 

 aperture does not depend on age, as D'Orbigny thinks. In this 

 indication of D'Orbigny's mistake, Defrance is correct ; the Li- 

 tuolce are very distinct from the so-called Spirolince, which are 

 narrow forms of Peneroplis planatus, F. & M. sp. See Ann. Nat. 

 Hist. ser. 3. v. pp. 297 & 466 &c. 



131. Spiroloculina, D'Orb. Diet. vol. 1. p. 299. Under this 

 head Defrance quotes nine fossil species from D'Orbigny's 

 Tabl. Meth. Ceph. (Ann. Sc. Nat. vii. p. 298). 



132. Spirula cylindracea. Lam. sp. Diet, xxxii. p. 190 ; Bl. 



* Lamarck figured two distiuct forms under this name, namely Penero- 

 plis cylindracea, and a Clavuline variety of Valvulina triangularis ( Valvu- 

 lina Clavulus). See Ann. Nat. Hist. ser. 3. v. p. 4^37 &c.
