INDEX TO THE HISTORIA CONCHYLIORUM 
Tab. Fig. 
644. 3 6. 1 urbo Pagoclus; and Klein, in the Methodus Ostracolog. t. 2. f. 3%. has copied this 
figure. 
645. 37. Trochus Labeo. 
646. 38. Trochus Tuber. 
— 39. A variety of Trochus ccelatus. 
647. 40. Trochus ccelatus . 
•— 41. Turbo rugosus; and Klein’s t. 2. f. 50. is a copy. 
648. 42. Is called Trochus coloratus in the Museum Geversianum, and is the Trochus No. 
125. of Schroeter’s Einleitung, but is rather an uncertain figure. 
— 43. Favanne, vol.ii. p. 17, calls this shell “ le Macaron;” and except that it constitutes 
the Trochus No. 126. of Schroeter’s Einleitung, I cannot find that any other no¬ 
tice has been taken of this figure. 
649. 44. Differs from Trochus vestiarius in having the whirls nodulous, and is the Rotella 
monilifera of Lamarck. 
650. 45. Trodhus vestiarius. 
— 46. Is the rose-coloured variety of Trochus vestiarius; which has been separated by 
Lamarck, and it is his Rotella i^osea. 
651. 47. Rotella monilifera of Lamarck; and is the same as fig. 44. ' 
— 48. Is the gray variety of Trochus vestiarius with longitudinal ziczac stripes; which is 
the Rotella suturalis of Lamarck: and he observes, “ Le bord superieur des 
u tours, etant saillant, fait paraitre les sutures enfoncees.” 
652. 49.1 y ar ie,ti es of Trochus vestiarius. 
— 50. j 
653. 51. Trochus Tectum. 
— 52. Trochus Modulus; and the reference in the Descriptive Catalogue to “le Grenat” 
of Favanne is erroneous. 
— 53. A variety of Trochus Tectum. 
654. 54. Trochus perlatus. 
656. 1. A decorticated shell of Cyprcea helvola. 
657. 2. Cyprcea Onyx. 
658. 3. Cyprcea Arabica. 
659. 3. a. Has been generally quoted for Cyprcea Histrio; but Lamarck, in the Annales 
du Musee d’Histoire Naturelle, vol. xv. p. 450, has justly observed, that it is a 
variety of Cyprcea Arabica “ plus margine, a dos parseme de petites taches irre- 
“ gulieres.” Tab. 21. f. 8. of the Museum Beslerianum is a reversed copy. 
660. 4. Cyprcea Isabella. 
661. 5. Cyprcea ziczac. 
662. 6. Is a young shell either of Cyprcea Histrio , or of Cyprcea Arabica. 
663. 7- The Cyprcea gibba of Gmelin has been entirely constituted from this figure, and it 
is a young shell of Cyprcea stercoraria. 
664. 8. Is obviously Cyprcea carneola; and the Cyprcea crassa of Gmelin has been entirely 
and absurdly constituted from this figure. 
665. 9. A young shell of Cyprcea, carneola. 
666. 10. Cyprcea Asellus. 
667. 11. The reference to this figure, and the whole of the first eight lines at page 444 of 
my Descriptive Catalogue, have been inserted by mistake, and ought to be en¬ 
tirely cancelled: it is a young shell of Cyprcea cinerea; and to the synonyms of 
that species at page 451, the Cyprcea cincta of Solander may be added. 
— 12. This shell has been arranged by Gmelin as a variety of Cyprcea Pyrum; and as a 
separate species in Solander s MS. with the name of Cyprcea umbilicata: it has 
the teeth of a saffron colour, and in Cyprcea Pyrum they are whitish. 
668. 13. Gmelin considered it to be Cyprcea cinerea; but Dr. Solander has quoted this figure 
for his Cyprcea baltheata , which, on the authority of Dr. Konig, is said to be a 
native of Coromandel: and I have never seen a shell which answers the de¬ 
scription. 
— 14. Cyprcea Talpa. 
669. 15. A young shell of Cyprcea exanthema. 
670. 16. Cyprcea cinerea. 
671. 17. Cyprcea lari da.
