438 Messrs. W. K. Parker and T. R. Jones on the 



This was figured by Parkinson (Org. Rem. 1811, pi. 10. f. 28- 

 31). It is one of the elongate-oval varieties (such as A. ovdidea, 

 D'Orb. Ann. Sc. N. vii. p. 806, no. 3) of A. Melo, F. & M. sp. 

 Ann. N. H. ser. 3. viii. p. 165. 



2. Nodosaria Rapa. Page 253, no. 27. Wrongly referred 

 to by D'Orbigny as a Lamarckian species. D'Orbigny applied 

 this term to the straight form of N. Raphanus, Linn, sp., and 

 indicated its Marginuline condition by the name of Marginulina 

 Raphanus, Ann. Sc. N. vii. p. 258, no. 1. See Ann. N. H. ser. 3. 

 xii. p. 213, and above, p. 432. 



3. Robulina aculeata. Page 289, no. 14. Under this name 

 D'Orbigny grouped some more or less rowelled forms of Cristel- 

 laria Calcar^, Linn, sp., figured by Fichtel and Moll, — namely, 

 their Nautilus Calcar, Linn., var. a (pi. 11. f. a-c), keeled and 

 rowelled (the type of this subspecies) ; var. 6 (pi. 12. f. i, k), keel- 

 less, slightly rowelled; var. /c (pi. 13. f. c, </), keel slight, with 

 some teeth (a specimen of C. Calcar developed but faintly in its 

 several features) ; and var. /x (pi. 13. f. h, i), sharply rowelled. 

 See Ann. N. H. ser. 3. v. p. 112. 



4. Rotalia (Turbinulina) tortuosa. Page 275, no. 40. Modele 

 no. 74. For this name D'Orbigny erroneously quotes Fischer 

 (who gives a figure of it under the name of Streblus Beccarii) as 

 the authority. See above, "Rotalia (Turbinulina) Beccarii," 

 p. 436. 



II. Species of Foraminifera illustrated hy D'Orbigny in the 

 Plates 10-17 of the 'Annales des Sc. Nat.' vol. vii. 1826. 



1. Amphistegina Lessonii, D'Orb. Ann. Sc. N. vii. p. 304, 

 no. 3, pi. 17. f. 1-4. Modele no. 98. From the Isle of France. 

 This differs from A. vulgaris, D'Orb., ibid. p. 305, no. 8, Modele 

 no. 40, in an exaggerated convexity of its faces ; and although 

 it stands before A. vulgaris in the 'Tabl. Meth.', yet the latter, 

 being foremost in the Models, and being the better type, may 

 well take precedence and bear the specific name. In 1825, 

 Defrance noticed an Amphistegina (fossil near Pisa and else- 

 where) as Nummulites ? Lenticula, which is not essentially distinct 

 from A. vulgaris, D'Orb. (Ann. N. H. ser. 3. xii. p. 211). For 

 a full account of Amphistegina, see Carpenter's ' Introd. Foram.' 

 p. 241, &c. 



2. Anomalina punctulata, D^Orb. Ann. des Sc. Nat. vii. 

 p. 282, no. 1, pi. 15. f. 1-3 bis. From the Isle of France. With 

 some exceptions, D'Orbigny's Anomalina are somewhat biconvex

 dicating the arrested, few-chambered thickish plano-convex mem- 



* D'Orbigny refers C. Calcar, Linn, sp., to C. Cassis, F. & M. sp. (Ann. 

 Sc. N. vii. p. 291) as well as to Robulina Calcar, Linn. sp. (op. cit. p. 289).
