Nomenclature of the Foraminifera. 437 



ceeds to note that it comes from the Mediterranean, and is 

 known to many authors, referring to the figures and descriptions 

 given by Gualtieri, Linne, Gmehn, and Martini of Ammonia 

 {Nautilus) Beccarii. Fischer therefore proposed a new generic 

 name only, not a specific name, for this Rotalia, which was 

 Linne's Nautilus Beccarii in 1758, and Lamarck's Rotalia 

 Discorbula in 1804. 



55. Siderohna calcitrapoides, Lamarck, sp. Page 297, no. 1 . 

 Essentially the same as Calcarina Spenglein, Gmelin, sp. Prof. 

 Reuss prefers to keep these apart (Sitzungsber. Akad. Wien, 

 1861, xliv. p. 315). Ann. N. H. ser. 3. v. p. 65, & vi. p. 341. 

 See also Calcarina Spengleri, above. 



56. Spirolina cylindracea, Lamarck. Page 286, no. 1. Mo- 

 dele no. 24. This is a very narrow Peneroplis planatus, F. & M. 

 sp. Ann. N. H. ser. 3. v. p. 466. 



57. Spirolina depressa, Lamarck. Page 287, no. 3. The 

 same as Peneroplis planatus, F. &. M. sp. Ann. N. H. ser. 3. 

 V. p. 466. 



58. Spirolina nautiloides, Lamarck. Page 287, no. 6. This 

 is very distinct from the other " Spirolinse " {Peneroplides) ; it 

 is a Lituola {L. nautiloidea, Lam.), as is also Spirolina aggluti- 

 nans, D'Orb. For. Foss. Vien. p. 137, pi. 7. figs. 10-12. The 

 misplacement of this species as a " Spirolina " was corrected by 

 Defrance. See also Ann. N. H. ser. 2. xix. p. 301 ; & ser. 3. v. 

 p. 297. 



59. Textularia Sagittula, Defrance. Page 263, no. 20. Ac- 

 cording to our view of the relationships of the Textularice, this 

 is T. agglutinans, D'Orb., var. Sagittula. Ann. N. H. ser. 3. xii. 

 p. 218. 



60. Triloculina oblonga, Montagu, sp. Page 300, no. 16. 

 Modele no. 95. A very common modification of Miliola Semi- 

 nulum ; often it is rather a contracted ill-grown Quinqueloculina 

 than a true Triloculina. Ann. N. H. ser. 3. iv. p. 343. 



61. Triloculina trigonula, Lamarck, sp. Page 299, no. 1, 

 pi. 16. f. 5-9. Modele no 93. Ann. N. H. ser. 3. v. p. 470. 



62. Truncatulina refulgens, Montfort, sp. Page 279, no. 5, 

 pi. 13. f. 8-11. Modele no. 77. We have given some particulars 

 of this interesting variety of Planorbulina farcta, F. & M., in 

 Ann. N. H. ser. 3. vi. p. 340. 



63. Vaginulina Legumen, Linn. sp. Page 257, no. 2. See 

 Ann. N. H. ser. 3. iii. p. 479. 



1^. The following Forms, already illustrated by Figures given by 

 older authors [not including Soldani), received names from 

 D'Oi'bigny, in the 'Annates des Sc. Nat.' vii. 1826, 



1. Alveolina oblonga. Page 306, no. 4. Fossil at Soissons.
