INDEX TO THE HISTORIA CONCHYLIORUM. 
Tab. Fig: 
548. 1 . Serpula lumbricalis. 
— 2. Serpula anguina. 
3. Has been generally considered to be Serpula Aquaria; but Lamarck has quoted 
the figure, with a mark of doubt, for his Aspergillum vaginiferum, which is a 
separate species. 
550. 1 . A young shell of Nautilus Pompilius. 
— 2. Nautilus Spirula. 
— 3. A young shell of Nautilus Pompilius. 
551. 3. a. Nautilus Pompilius. 
552. 4. Nautilus scrobiculatus. 
553. 5. Serpula spirorbis. 
554. 5. a. Is probably a young shell of Argonauta Gondola, 
o 55. 6. Argonauta hians. 
55 6 . 7 - Argonauta Argo; copied from the Museum Calceolarianum, p. 36 . 
557. 7 .f Argonauta Argo, with its inhabitant; copied from Aldrovandus de Testaceis, p. 
260 . 
559 . 1. Nerita Canrena , variety D; which is the Natica lineata of Lamarck. 
2. Quoted by Gmelin for his Nerita melanostoma, but is too uncertain a figure to be 
worth notice. 
560 . 3. Nerita Canrena , variety E. 
— 4. Nerita Canrena , variety A. 
— 5. Nerita Canrena , variety L. 
561 . 7- Nerita Canrena, variety I: which is the Nerita Zebra of Chemnitz; and is also 
arranged by Lamarck as a separate species. 
— 8. The want of a description renders it difficult to ascertain this figure. 
5 62 . 9 . Is probably an old shell of Nerita glaucina; but in the Museum Geversianum is 
arranged separately, with the name of Nerita pressa. 
563. 10. By different authors it has been quoted for Nerita Canrena, Nerita glaucina, and 
Nerita Albumen, and is rather an uncertain figure. 
564. 11. Nerita Canrena, variety B ; and is arranged as a separate species by Lamarck, with 
the name of Natica millepunctata. 
565 . 12. Nerita Nit ell us. 
■— 13. Quoted for a variety of bis Nerita melanostoma by Gmelin; but is arranged sepa¬ 
rately by Meuschen, with the name of Nerita cana, and is an uncertain figure. 
566. 14. Nerita Mammilla, variety B; but is most probably a distinct species: and it is er¬ 
roneously considered by Lamarck to be the Linnean Helix mammillaris. 
— 15. Helix mammillaris. 
— 16 . Nerita cancellata. 
5 67 17- Neritafulminea. 
— 18. Variety of Nerita fulminea. 
568 . 19 . Nerita glaucina. 
569 . 20 . Variety of Nerita glaucina. 
570 . 21. Helix heliotoidea. 
571 . 22 . Nerita Mammilla, variety A. Petivers Gazophylacium, t. 152. f. 12 . is a bad copy 
from the uppermost of these figures. 
572 . 23. Helix ianthina. 
— 24. Helix ianthina, with the animal; and this figure has been copied from Columna de 
Purpura, p. 13. 
— 25. An old shell of Nerita Canrena, with the umbilicus nearly closed. 
373 . 23.f Belongs to the genus Ianthina of Lamarck ; and Mr. G. Sowerby informs me, that 
it is the species which in the fifth number of his “ Genera of Shells” is mentioned 
under the name of Ianthina globosa. 
574. 26.1 Have been copied by Klein, in his Methodus Ostracolog. 1.1. f.4. and 5 ; and er- 
— 27 . ) roneously quoted by Gmelin for varieties of Helix nemoralis. 
575. 28. Gmelin has been misled by Chemnitz to quote this figure, with a mark of doubt, 
for Turbo coronatus, and afterwards for a variety of Turbo granulatus. Meuschen, 
in the Museum Geversianum, calls it Trochus spinosus ; and it constitutes the 
Turbo No. 12. of Schroeter’s Einleitung. Favanne also has referred to this figure 
for his (i petit Olearia granuleux,” and it is probably a variety of Turbo granulatus.
