"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.
Gualt. t. 87. f. C.
Testa reliquis magis gibba, albido-flavescens, sulcis xxx obtusis,
transversim nodosis: nodis transversis, obtusissimis, imbricatis.
Intus albida. Margo dentibus xxx argutiusculis. Rima sulco rhombeo
circumscripta, disco decussatim vix manifeste striato. Umbones distantes
ad neutrum latus flexi.
A. SENILIS. _A._ oblique cordata, octosulcata, lævis, antice hians, rima
obtusangule striata.
Lister (without numerals!) was referred to in illustration; the early
unimproved account of the beaks and ligamental area ran as follows:
"Umbones distantes, oblique incurvati. Rima hians striata transversim ad
angulos acutos": "et profunde immersis" was an addition.
A. GRANOSA. _A._ subcordata, sulcis muricatis, rima obtusangule striata,
utrinque angulum formante.
The name was evidently borrowed from Rumphius, whose _Pecten granosus_
("143. t. 44. f. K.") was referred to in the manuscript, though neither
quoted in the printed copy nor in the 'Systema' (ed. x.). "Bonan. 2. n.
73," and Lister (without numerals) were also cited.
A. DECUSSATA. _A._ lenticularis, decussatim substriata, apicibus
reflexis.
For a detailed account of this shell, to which no specific name was
attached in the MS., the 'Museum Ulricæ' was referred to, previous to
its publication.
A. PALLENS. _A._ lenticulari-subobliqua, decussatim striata, rima brevi.
