T ab. Fig. 
576. 29. Is generally considered to be Turbo Porphyrites, but is rather an uncertain figure. 
— 30. Is another ratber uncertain figure, and has been only quoted by Favanne for “ la 
“ Neffle,” vol. ii. p. 86. 
577- 31. Helix Scarabaus. 
— 32. Is the Helix Scarabcrvs, variety B of the Descriptive Catalogue; but has been ar- 
ranged separately by Ferussac, with the name of Scarabus plicatus. Klein, 1.1. 
f. 24. has copied this figure. 
— 32. a. Is the Voluta No. 144. of Schroeters Einleitung; and is probably a distinet 
species, allied to Voluta Auris Cati. 
—• 32. b. Is the Bulimus Auricula of Bruguiere, the Auricula auricella of Ferussac, and 
the Tornatella Auricula of Lamarck. The species is not noticed in my Descrip¬ 
tive Catalogue. 
578. 33. Helix flammea. 
5 7.9- 34. This shell has been generally confounded with Bulla achatina, but differs in having 
the suture depressed with a marginal indented line; and it is the Achatina mar¬ 
ginata of Swainson. Petiver, in the Gazophylacium, t. 152. f. 11. has copied this 
figure. 
580. 34. a. Young sliells of Bulla achatina. 
581. 35. Bulla purpurea. 
582. 35. a. Is the Bulimus fulvus of Bruguiere, and the Helix fulvescens of Ferussac; 
which species was considered by Mulier to be a variety of Bulla Achatina. 
583. 36. Is the Turbo No. 62. of Schroeters Einleitung, and the Turbo No. 58. of Schrei- 
bers Conchylien; and I cannot find that it has been noticed by any other author. 
— 37. Helix scabra. 
— 38. Trochus ziczac. 
584. 39- Turbo Petholatus. 
— 40. Turbo Cochlus. 
— 41.1 cannot find that any author has noticed this figure except Schrocter, and it con¬ 
stitutos the Turbo No. 63. of his Einleitung. 
— 42. Trochus Labeo. 
585. 43. Turbo littoreus. 
— 44. Turbo Pullus. 
586. 45. Young shell of Turbo Cochlus. 
587. 46. Turbo marmoratus. 
588. 47. Is the Helix decumanus of Ferussac; and has been quoted erroneously in the De¬ 
scriptive Catalogue for Turbo sulcatus. 
— 48. Turbo Mumia. . 
— 49. Turbo Alvearia. 
— 50. Turbo pulcher. 
— 51. upper fig. Turbo Clatkrus. 
— 51. lower fig. Turbo Clathratulus. 
— 52. Turbo crenatus. 
589- 53. Turbo obsoletus; and I rather doubt whether Petiver’s Gazophylacium, t. 46. f. 7. 
has not been borrowed from this fisure. 
590. 54. Turbo Archimedis. 
— 55. 'j 
591. 56. bAre generally considered to be varieties of Turbo Terebra. 
— 57.) 
— 58. In the Descriptive Catalogue I have followed Maton and Raekett in quoting this 
figure for Turbo duplicatus, and it is more like a worn shell of Turbo exoletus. 
— 59. Turbo acutangulus. 
592. 60. Turbo exoletus. 
593. 6l. The species to which this figure belongs is doubtful; and I believe it has not been 
noticed by any author, except that it is the Turbo No. 140. of Schroeters Einlei¬ 
tung. 
595. 1. Nerita Peloronta. 
— 2. Is the Nerita No. 120. of Schroeters Einleitung, and “ la Nerite allongee” of Fa¬ 
vanne, vol. ii. p. 225. t. 10. f. Q. 
— 3. Nerita plicata.
