The erroneous reference to Gualtieri was not present in the written copy.
Mention was made in the 'Systema' of a Solen bullatus, for a more detailed account of which the reader was referred to the 'Museum Ulricæ.' No such species appeared in the published edition; but the omitted shell (a veritable Cardium) was thus described in the unprinted version:—
Buc. bullatum. B. subrotundum, antice crenato-hians.
Rump. 143. t. 44. f. N. Pecten bullatus.
Testa subrotunda, inflata, gibba, fragilis, pellucida, substriata, rufo nebulosa, antice hians, margine serrato. Umbones tumidi, obtusi, reflexi. Rima minima brevissima. Ani regio obsoleta. Dens cardinis fere unicus, minimus. Marginales solitarii, remoti, compressi, majores.
DONAX.
Trunculus was the proposed name of this genus, which was thus characterized:—
Testa compressa, antice obtusissima, retusa. Cardinis dentibus 2, marginis unicus.
D. scortum was wisely omitted.
