1044. 23. c. Ammonites Conybeari of Sowerby. 
1045. 23. d. Ammonites Blagdeni of Sowerby. 
1046. 23. e. Ammonites giganteus of Sowerby. 
1047 - 23. f. Is most probably a broken cast of the Nautilus intermedius of Sowerby; and 
although on a reduced scale, I greatly doubt whether Favanne’s t. 66. f. C 3 .. is 
more than an inaccurate copy, and whether some other of Favanne’s figures 
have not in like manner been borrowed from Lister. 
1048. 23. g. Nautilus truncatus of Sowerby. 
1049. 24. Ammonites discus of Sowerby. 
1050. 25. Is probably a section of the foregoing species. 
1051. 26. Is the inside cast of a Cirrus, which is common in the black marble at Llanga- 
darne in Carmarthenshire; and I doubt whether it is more than a variety of the 
Cirrus acuta of Sowerby, with the spire depressed. 
1052. 2/. Is the Ammonites turbinata of Bruguiere, and belongs to the genus Solarium of 
Lamarck. 
1053. 28. Euomphalus gent, angulatus of Sowerby. 
— 29. Is probably an inside cast of the Natica patula of Sowerby. 
1054. 30. Ammonites reniformis of Bruguiere; and the figures are taken from the Historia 
Animalium Angliae, t. 6. f. 10.

Helix ovata. 
Helix hamastoma. 
Is the Helix No.95. of Schroeters Einleitung; and has been erroneously quoted 
by Gmelin for a variety of Helix nemoralis. 
Helix zonulata of Ferussac; and in the Descriptive Catalogue has been erroneously 
quoted for Helix Cornu Venatorium instead of 1 . 1058 . f. 3 . and 4 . 
Helix Carocolla. 
Helix vivipara. 
The Buccinum No. 191. of Schroeter’s Einleitung, and the Buccinum Acicula of 
Gmelin, have been entirely constituted from this figure; and it is certainly 110- 
thing more than a shell of Strombus ater, with the outer lip imperfect. 
A variety of Helix Amarula. 
Mytilus castaneus of Solander, which is the Modiola Vagina of Lamarck; and the 
species has been omitted in the Descriptive Catalogue. 
This species has been generally confounded with Mya Valsella, but has been se- 
parated by Lamarck, with the name of Vulsella hians. 
Vmus fimbriata. 
1 have not met with any reference to this figure, and the want of a description ren- 
ders it almost impossible to ascertain the species. 
Is probably an unusually large shell of Teredo navalis. 
Dentalium Entalis. 
Solen Vagina. 
- £} 
. Haliotis imperforata. 
1057. 
Bulla Ampulla. 
Buccinum granula,tum. 
Quoted by Maton and Racket for Murex sub antiquatus. 
Is probably Murex fornicatus: but there are so many intermediate varieties, that 
I confess my inability to distinguish cither Murex fornicatus or Murex suban- 
tiquatus from Murex despectus; and Martini considered not only these, but 
Murex antiquus also, to be only varieties of one species. 
Venus Islandica. 
Ostrea cinnabarina. 
Is the Mytilus rusticus of Solander’s MS. and the Modiola Papuana of La¬ 
marck ; which species has been generally confounded with Mytilus Mo¬ 
diolus.
