INDEX T0 THE HISTORIA CONCHYLIORUM. 
Born has erroneously cited this figure for Helix fuscata; and it is placed separately 
by Schroeter in the Einleitung, vol. ii. p. 199- Helix No. 78. and in the Flusscon- 
chylien, p. 358. Petivers t. 105. f. 7- has been copied from it. 
Helix cuspidata. 
Has been considered by Mulier, Schroeter, and Gmelin to be Helix Vibex, but is 
more like a young shell of Strombus auritus. I may here remark, that in the 
Descriptive Catalogue, p. 950, under the head of Helix Vibex, a reference to 
Chemnitz, ix. part 2. p. I89. t. 136. f. 1261. and 1262. has been accidentally 
omitted, and that the reference to the Berlin Magazine should be erased. 
Klein has copied this figure in his Meth. Ostracolog. t. 2. f. 38; and Gmelin 
has followed Martini and Schroeter in placing it as a separate species, with the 
name of Murex fuscus : but it appears to me to be at most only a variety ot 
Murex torulosus. 
Strombus auritus; in the same manner as in the foregoing species : the Murex fas¬ 
ciatus of Gmelin has been wholly and very unwarrantably constituted from this 
figure, although he has also quoted it for Strombus auritus. The reference to 
this figure for Murex torulosus in the Descriptive Catalogue is erroneous, and 
1.120. f. 15. should be substituted. 
Murex fuscatus. 
A young shell of Murex Radula. 
Is the Murex No. 51. of Schroeter’s Einleitung; and I have not met with any other 
reference to this figure. 
Murex Radula. Gmelin has erroneously quoted this figure for Strombus aculeatus; 
and his Murex fluviatilis has been wholly derived from it. 
Helix stagnatis. Both this and the two following figures have been copied by 
Buonanni in his Ricreatione, part 3. f. 53. to 55. from the Historia Animalium 
Anglise, with a simple correction of the unnatural turn which Lister had given 
to the whirls ; and with this correction the same figures are here again pub- 
lished. 
Helix auricularia. 
Helix putris. 
Bruguiere has quoted this figure for a variety of Helix palustris, with the following 
observation: “Lister l’a representde avec son animal, mais je dois prevenir que si 
“ la forme de la coquille convient, celle de 1’animal est fautive, a cause des tenta- 
“ cules qu’elle represente lineaires, tandis qu’ils sont effectivement triangulaires et 
“ plats, avec les yeux placas interieurement a leur base.” Draparnaud also con- 
siders it to be that large variety of Helix palustris, which Gmelin has followed 
Schroeter in arranging as a separate species, with the name of Helix Corvus. 
Helix Urceus. 
Helix vivipara. 
Several authors have followed Mulier in quoting this figure for Helix angularis; 
but it is perfectly different, and is the Paludina decisa of Mr. Say, with specimens 
of which from New York I have been favoured by Dr. Mitchell. Petiver, in the 
Gazophylacium, t. 106. f. 18. has copied this figure. 
Ampullaria Guyanensis of Lamarck: which he says differs from Helix Urceus “en 
“ ce qu’elle n’offre que des stries d’accroissement; son ombilic est en outre plus 
“ evase, et la coloration de son ouverture est differente.” 
Helix glauca. 
Is generally considered to be a variety of Helix ampullacea, but has been separated 
by Mr. Swainson, with the name of Ampullaria fasciata. 
Is the Helix No. 83. of Schroeter’s Einleitung: but it has not been noticed by 
Gmelin, and I am unacquainted with the species. 
Helix tentaculata : and it has been copied from the Historia Animalium Angi ire, 
t. 2. f. 19. so as only to correct the left-handed appearance of the whirls. 
Helix Amarula. 
Bulla fontinalis : and it has been copied from the Historia Animalium Angliae; ex- 
cept that the figure is inverted, so as to give the whirls their customary turn, in 
opposition to the generality of shells. 
135. 35. Bulla crassula ; and Petivers Gazophylacium, t. 106. f. l6. is a copy.
