D'Argenville was not referred to.
V. reticulata. Cun. subcordatus, striis crenatis decussatis, ano cordato.
V. tigerina. Cun. suborbiculatus, striis crenatis decussatis, ano ovato.
The name was an error, having been derived from the "Lingua tigerina" of Rumphius (his figure G., not H.): fuliginosus was the one originally intended.
V. prostrata. Pho. orbiculata, transverse striata, labiis scabro-membranaceis.
The unpublished details had been previously referred to in the 'Systema.'
V. Pennsylvanica. Pho. glabra, rugosa, antice sulco longitudinali.
"Habitat in Pennsylvania," and "subdiaphana," were the unprinted additions. The "margo interne crenatus," "nates sub-recurvatæ," and "color intus versus marginem violaceus," were not in the copy. The last character (so utterly inappropriate to the features of Lucina P.) was, I suspect, intended for punctata on the page opposite.
V. incrustata. Pho. glaberrima lævissima, punctis excavata.
The details were referred to in the 'Systema' before their publication.
