PATELLA.
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'.
