Tab. Fig. 
Da Costa’s Conchology, p. 5. t. 1. f. 8; and it appears from the references, that 
they considercd both Patella Ulyssiponensis and Patella lugubris to be only va- 
rieties of tbe same species. 
537. 17. Patella mammillaris; and tbe Patella striatula of Humphreys and Da Costa’s 
Conchology, p. 24. t. 4. f. 15. may be added to the synonyms of this species. 
— 18. Is the Patella sanguinolenta of Gmelin, and Patella puncturata of Lamarck; which 
species in the Descriptive Catalogue has been mistaken- for a young shell of Pa¬ 
tella miniata, but is perfectly distinet. 
— 19. Is probably a variety of Patella octocostata; see t. 532. f. 11: and Klein, in his 
Methodus Ostracolog. t. 8. f. 2. has copied this figure. 
— 20. Favanne lias quoted this figure for Patella rustica; and the difference in its ap- 
pearance may possibly be accounted for by his observation, “ il y en a de fort 
“ elevees, dont la forme est moins ovale; d’autres au contraire tres-applaties, dont 
“ fovale est alonge.” Humphreys and Da Costa, on the other band, have cited it 
for the Linnean Patella reticulata; but it appears different from the shell which 
Schroeter has figured for that species. 
538. 21. upper fig. Patella miniata; and to this species the Patella pulchra of Humphreys 
and Da Costa’s Conchology, p. 12. t. 2. f. 8. may be referred. 
— 21. lower fig. Patella angulosa. 
539. 22. Patella leucopleura; and the Patella Zebra of Humphreys and Da Costa’s Con¬ 
chology, p. 7. t. 1. f. 9. is the same species. 
— 23. An old and worn shell of Patella leucopleura. 
540. 24. This shell is also figured, but without a name, in Humphreys and Da Costa’s Con¬ 
chology, 1.1. f. 2 ; and I am unable to decide whether it is a Patella, or the valve 
of an Acardo. 
541. 25. Patella compressa; and Humphreys and Da Costa, though they have called it Pa¬ 
tella Cymba, considercd this species to be the Patella rustica of Linneus. See 
Humphreys and Da Costa’s Conchology, p. 4. 1.1. f. 7. 
542. 26. Patella Icevis; and these figures have been taken from the Appendix to the Historia 
Animalium Angiise, t. 2. f. 10. and again copied by Klein, in his Methodus Ostra¬ 
colog. t. 8. f. 6. and 7- 
543. 27. Patella pellucida. 
_ 28. PatellaJissura. 
544. 29. Favanne has quoted this figure for “ le Capuchin de moinewhich he says is a 
scarce species, and inhabits the coasts of Africa. See Favanne, vol. i. p. 538. 
t. 4. f. A. 
_ 30. This shell has been generally confounded with Patella antiquata, but is perfectly 
distinet, and is the Pileopsis subrufa of Lamarck. Petivers Gazophylacium, 
t. 152. f. 13. and Klein’s t. 8. f. 9. have been copied from this figure. 
— 31. Patella antiquata; and Klein has copied these figures in his Methodus Ostracolog. 
t. 8. f. 11. and 12. The Patella pileata of Humphreys, p. 22, t. 4. f. 6. belongs 
to this species ; and the reference to Humphreys in the Descriptive Catalogue is 
erroneous. 
_ 32. Patella militaris; and this species has been erroneously namcd Patella antiquata 
in Humphreys and Da Costa’s Conchology, p. 22. t. 4. f. 10. Petivers Gazophy¬ 
lacium, t. 152. f. 15. is a copy. 
545. 33. Patella fornicata. 
— 34. Patella porcellana. 
_ 35. Variety of Patella fornicata. 
— 36. Patella neritoidea. 
_ 37. Is probably Patella crepidula, for which it has been quoted by Favanne. Klein’s 
t. 8. f. 8. has been copied from this figure. 
546. 38. Patella equestris. 
— 39. Patella Sinensis. 
547. 1. upper fig. Dentalium elephantinum; and this figure has been taken from Buo- 
nanni’s Ricreatione, part 1. f. 8. 
— 1. lower fig. Dentalium striatum. 
— 2 . Dentalium Entalis. 
— 4. Serpula decussata.
