Testa conica, convexa. Spira regularis nulla vera.
The limits of this genus were precisely those of the printed edition.
P. EQUESTRIS. _P._ ungue fornicali nutante.
P. NERITOIDEA. _P._ integra ovata, apice subspirali, labio laterali.
"Supra" preceded "convexa", and the "fere" was before "apice".
P. CHINENSIS. _P._ conica latior lævis, labio interno laterali.
This was an addition to the original catalogue.
P. PORCELLANA. _P._ basi interne labiata, pone mucronato-subspiralis.
P. CREPIDULA was not mentioned in the manuscript.
P. SACCHARINA. _P._ margine sinuato, carinata, costis 7.
"Pet, Amb. t. 3. f. 3", and "Klein 117. t. 8. f. 4", were additional
synonyms: both are in the 'Systema.'
P. BARBARA. _P._ dentata, costis 19 elevatis.
P. GRANULARIS. _P._ margine dentato, striis elevatis mucronibus
imbricatis.
The erroneous reference to Gualtieri was not in the original.
P. GRANATINA. _P._ margine angulato, striis 11 lævibus.
"Interius" was the earlier reading of "subtus".
P. TUBERCULATA. _P._ dentata conica tuberculata, postice sima.
_Sima_ was the earlier name in the MS., but was erased by Linnæus.
P. LUTEA. _P._ integerrima striata, vertice mucronato inflexo.
P. UNGUIS. _P._ ovali-oblonga, apice emarginata, mucrone dorsali
carinato.
_Unguiformis_ was the intended appellation.
P. TESTUDINARIA. _P._ ovata glaberrima integerrima.
P. RUSTICA. _P._ integra, striis 50 obtusiusculis.
P. FUSCA. _P._ ovata integerrima, striis elevatis, vertice obtuso.
The intended name was _cinereo-nigricans_.
P. CRUCIATA. _P._ ovalis convexa integerrima, cruce picta.
P. RETICULATA. _P._ conica compressa, superficie reticulata.
The suggestion I have elsewhere made that this uncertain shell might
prove the European _Pedicularia_, induces me to remark that, although
_P. Sicula_ has been supposed to be a comparatively modern discovery,
Favanne had long ago delineated it in the fourth plate (f. H. 1.) of
his enlarged edition of d'Argenville.
P. NIMBOSA. _P._ conica ovalis, costis confertis, vertice perforato.
The discrepancy between the heading borrowed from the 'Systema', and
the after details, is removed by the substitution of the original one.
The shell was termed _perforata_ (not _nimbosa_), and was wrongly
identified by Linnæus with the striated brown _Fissurella_ of the
'Systema'.

In addition to the printed species, the two following were present in
the manuscript copy.
P. SOLARIS. _P._ ovata integerrima, striis subnodosis, vertice
acutiusculo.
Testa ovata, diaphana, magnitudine extimi articuli digiti, margine
integerrimo, lævis, striis subtilissimis inæqualibus numerosissimis,
fasciis longitudinalibus rubris albo passim maculatis. Mucro
acutiusculus obliquus albidus.
This was placed in the section having a simple margin.
P. PERFOLIATA. _P._ conica, reclinata, perfoliata.
Testa magnitudine coryli nucis, conica, sed cono retro inclinato,
acutissima, alba, imbricata lamellis horizontaliter testam
cingentibus. Margo integer, ovalis, antrorsum gibbus s. dilatatus.
Cavitas profunde glabra.
This description very fairly suits the _Patella antiquata_ of the
twelfth edition of the 'Systema'.
