Tab. Fig. 
576 . 29 . Is generally considered to be Turbo Porphyrites, but is rather an uncertain figure. 
—• 30. Is another rather uncertain figure, and has been only quoted by Favanne for “ la 
44 Neffle,” vol. ii. p. 86 . 
577 . 31. Helix Scarab<xus. 
— 32. Is the Helix Scarabceus , variety B of the Descriptive Catalogue; but has been ar¬ 
ranged separately by Ferussac, with the name of Scarabus plicatus. Klein, t. 1 . 
f. 24. has copied this figure. 
— 32. a. Is the Valuta No. 144. of Schroetcr’s Einleitung; and is probably a distinct 
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 jlammea. 
579 . 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 shells 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 Muller to be a variety of Bulla Achatina. 
583. 36 . Is the Turbo No. 62 . of Schroeter s Einleitung, and the Turbo No. 58. of Schrei- 
ber’s Conchylien; and I cannot find that it has been noticed by any other author. 
. — 37 . Helix sca.bra. 
— 38. Trochus ziczac. 
584. 39 . Turbo Petholatus. 
— 40. Turbo Cochins. 
— 41. I cannot find that any author has noticed this figure except Schroeter, and it con¬ 
stitutes 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 Fertfssac; 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 Clathrus. 
— 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 figure. 
590 . 54. Turbo Archimedis. 
— 55 'Tl 
591 . 56. I-Are generally considered to be varieties of Turbo Terebra. 
— 57 .) 
— 58. In the Descriptive Catalogue I have followed Maton and Rackett 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 Schroeter s Einlei¬ 
tung. 
595. 1. Nerita Peloronta. 
— 2. Is the Nerita No. 120. of Schroeter’s Einleitung, and “ la Nerite allong^e” of Fa¬ 
vanne, vol. ii. p. 225. t. 10. f. Q. 
-— 3. Nerita plicata.
