"Nates, &c." and "Cardo, &c." were the printed additions to the earlier description. The 'Systema' synonyms of Klein (t. 8. f. 16) and Bonanni (2. f. 128) were present in the manuscript.
A. Noæ. A. oblonga angulata hians.
This manuscript furnishes us with the additional synonyms of
"Aldrov. 3. p. 513." and "Sloan. Hist. 2. p. 257. Musculus Matthioli," besides the previously published references to Lister (368. n. 208) and Bonanni (2. t. 32). The formation of the hinge was not, however, indicated, and the passage commencing with "Nates" has been enlarged from "Umbones remotissimæ, area interjecta concava, ad angulum rectum striata. Margo exterior in medio hians, apertura barbata."
The intended specific epithet was A. Noemi.
A. antiquata. A. testa oblique cordata, transversim sulcata, antice angulo compresso, rima intra rhombum transversim striata.
The admixture of two species (at the least) in the published edition resulted from the amalgamation of two earlier descriptions. To the above diagnosis belonged the printed details with the following important changes. In place of "extus striata longitudinaliter sulcis crenatis," the reading was simply "intus striata longitudinaliter," and in lieu of "interjecto spatio rhombeo plano," merely "rima patens."
The proposed name for this shell, from a supposition of its identity with the Pecten virgineus of Rumphius, was A. virginea. The other species which Linnæus referred to the same numerals of the 'Systema' was not named, but was thus characterized:—
A. (Sys. n. 144). A. cordata, sulcis nodosis, rima decussatim striata.
List. Hist. ... Pecten polyleptoginglymus, &c.
