Helix lucerna. 
Helix sinuata. 
Is a common variety of Helix sinuata; and Petiver’s Pterigraphia, 1.10. f. 13 . and 
14 . are copies. 
99 - 100. Helix ringens. 
LAND SNAILS. 
101. 101. Limax agrestis of Linneus. The engravings ofthe genus Limax in the Encyclo- 
pedie Methodique, t. 84 . and 85 . have been almost entirely borrowed from this 
and the four following figures. 
— 102. Limax ater of Linneus. 
101 .a. 103 . Limax rufus of Linneus. 
— 104 . Variety of the Limax maximus of Linneus. This and the three preceding figures 
were originally published by Lister, in his Historia Animalium Angliae and its 
Appendix. 
101. b. — Limax flavus of Linneus.

FRESHWATER UNIVALVES. 
108 . 1. Appears to me to be Helix substriata: but Bruguiere has given an opinion, that 
it is a bleached shell of his Bulimus radiatus , which is the Helix detrita of 
Mulier. Martini, who, in the Berlin Magazine, iv. t. 10. f. 46. has copied this 
figure; and Schroeter, in the Einleitung, ii. p. 196. No. 68; have however placed 
it as a separate species. See also Schroeter’s Flussconchylien, p. 340 . 
109. 2. Martini, in the Berlin Magazine, has copied the uppermost of these two figures, 
and they are both referred to for the Helix No. 69. of Schroeters Einleitung. 
See also the Flussconchylien, p. 343 . 
110. 3 . In the Berlin Magazine, iv. t. 10. f. 53 . a. this figure has been copied ; and also by 
Petiver, in his Gazophylacium, t. 105 . f. 9: and in Schroeters Einleitung it con- 
stitutes his species of Helix No. 70. 
— 4 . Mr. Say suspects that this belongs to his Paludina Virginica; and it is most pro- 
bably a variety of that species. Martini’s Berlin Magazine, iv. t. 10 . f. 53 . b. and 
Petivers t. 105 . f. 8 . have been copied from this figure; which constitutes the 
Helix No. 71. of Schroeters Einleitung. 
111. 5 . Is the Bulimus carinatus of Bruguiere, which is a species not described by 
Gmelin: and Petivers Gazophylacium, 1 . 104 . f. 6. is a copy. 
112. 6. Quoted by Bruguiere as a variety of his Bulimus carinatus, but is arranged sepa- 
rately by Schroeter in the Einleitung, and constitutes his species of Helix No. 
73 . Petiver has taken his 1 . 104 . f. 7. from this figure. 
1 13 . 7 - Buccinum Virgineum. Petivers t. 104 . f. 8. and Martini’s Berlin Magazine, t. 10. 
f. 48 . have both been copied from this figure: and our knowledge of the species 
was wholly derived from it when the Descriptive Catalogue was published; but 
it has since been described by Mr. Say, with the name of Paludina Virginica. 
114 . 8. Schroeter considers this and the following figure to be the same species, and they 
are together quoted in the Einleitung for his Helix No. 75. Petivers t. I06. 
f. 15 . is a cdpy. 
— 9. Quoted jointly with the foregoing figure by Schroeter, and I am unacquainted with 
the shell. 
115 . 10. Strombus ater. 
116. 11. This has been quoted by Mulier for his Nerita lineata, and by Chemnitz for his 
Helix ater; and it may be doubted, whether both of these are not young shells 
of Strombus ater in somewhat different stages of growth, and with the outer lip 
stili unexpanded. Bruguiere has also quoted this figure both for his Bulimus 
terebratis and his Bulimus fuscatus, which are the two corresponding species.
