Tab. Fig. 
812. 21. Gmelin has quoted this figure for Voluta musica; and it constitutes the Voluta No. 
146. of Schroeter’s Einleitung: Lister however considered it to be the same 
species as fig. 18 ; and it is not unlikely to be a young shell of V'Auta ehraa. 
— 22. Voluta Faba. 
813. 23. Voluta Dactylus. 
— 23. a. Voluta crenulata. 
814. 23. b. Voluta Conus. 
— 24. Voluta flammea. 
815. 25. Voluta Pyrum: and this figure has probably been engraved by copying fig. 194.of 
Buonannfs Ricreatione on the copper-plate, so as in the impressions to correct 
the left-handed appearance of the original. 
816 . 26. A young shell of Voluta Pyrum. 
— 27. VAuta Pyrum, at a stili earlier stage of its growth than fig. 26. 
817. 28. Has been generally considered to be Voluta Prunum, which it much resembles: 
but in Dr. Solander’s MS. it is quoted, though with a mark of doubt, for another 
species, with the name of Voluta glauca; and this in Calonne’s Cataloguc is said 
to be a West Indian shell. It differs from Voluta Prunum in having the spire 
longer; and I never saw that species fasciated, as is represented in this figure. 
818. 29. Voluta glabella. 
— 31. Variety of Voluta glabella. 
— 32. Voluta picta, not fully grown. 
819- 33. Voluta Barbadensis; and the species was first constituted by Schroeter and Gmelin 
from this figure. 
— 34. The Voluta No. 150. of Schroeter’s Einleitung, which is the Voluta clatkrata of 
Gmelin, has been constituted from this figure; and it appears to me to be a va¬ 
riety of Voluta nodulosa. 
— 35. Voluta paupercula. 
— 36 . Voluta texturata. 
820. 37. Voluta plicaria. 
821. 38. Voluta sanguisuga. 
— 39. Dr. Solander has quoted this figure for his VAuta spinulosa; and it is probably a 
variety of Voluta cruentata. 
822. 40. Voluta Rujflna. 
822. b.41. Buccinum plumatum. 
— 41. b. A worn shell of Murex crassus. 
823. 42. A young shell of Voluta torva, with the outer lip unformed. 
824. 43. Voluta mercatoria. 
— 44. Voluta rustica. 
825. 45. Is Voluta Tringa; and in the Descriptive Catalogue I have erroneously followed 
other authors in quoting this figure for Voluta rustica. 
— 46. Voluta rustica. 
826. 47. Voluta mendicaria. 
— 49. J 
827. 49. a. Buccinum nitidulum. 
— 49. b. Is the Voluta acuminata of Solander, which name has been preoccupied by 
Gmelin for a very different shell; and the species has not been noticed in the 
Descriptive Catalogue, but is the Voluta gracilis of my MS. It differs from Vo¬ 
luta Tringa in being narrower, and in having a longer spire; of which the sum- 
mit is always tinged with violet, and the pillar only obsoletely toothed. From 
Petivers description, his tab. 30. f. 6. appears to be the same species; and it not 
uncommonly occurs among West Indian shells. 
— 49. c. A young shell of Cypraa Europaa. 
— 49. d. Is the Buccinum No. 75. of Schroeters Einleitung; and is probably a variety of 
the species which Mr. Sowerby, in his work on the Genera of Shells, has figured 
with the name of Columbella Terpsichore. 
— 49. e. Is generally called the black variety of Voluta rustica; and has been deseribed
