CYPREA.

Testa ovata lævis involuta. Apertura linearis, utrinque dentata. Spira occultata intra testam.

C. mappa. C. subturbinata characterisata, macula longitudinali dentata.

"Pet. Amb. t. 16. f. 2." was an omitted synonym. The terminal remark is an improvement upon the earlier "Noscitur linea utrinque dentata in superficie scripta."

C. Arabica. C. subturbinata characterisata, macula longitudinali simplici.

"Denticulis testaceis" and the description of the variety were additions by the hand of Linnæus.

C. Argus. C. subturbinata subcylindrica, maculis annularibus.

The synonyms of Petiver (t. 97. f. 6) and Bonanni (f. 263), quoted in the 'Systema,' were also present in the MS., where "2. s. 1" was in the place of "duabus." The "pallidis" was a misprint for the written "pallidæ." The account of the variety was subsequent to the copy.

C. testudinaria. C. obtusa cylindrica, extremitatibus depressis.

"Pet. Amb. t. 8. f. 7." was an unprinted synonym.

C. carneola. C. subturbinata pallida, fasciis incarnatis.

C. talpa. C. subturbinata violacea, fasciis pallidis.

"Pet. Amb. t. 16. f. 1." was an unprinted synonym: "pallide flavescens" was the earlier reading for "testacea." The final remark was not in the copy.

C. Amethystea. C. subturbinata, dorso violaceo.

Rumphius was not originally cited as illustrative.

C. Vanelli. C. subturbinata, maculata punctis lutescentibus.

"Obsoletis" was originally in the place of "acutis": the "sæpe lutescentibus" was an addition of the press. C. Ovum Vanelli was the intended designation.

C. lota. C. subturbinata alba, denticulis subulatis.

C. fragilis. C. subturbinata gibba fragilis, obsolete fasciata.

Linnæus himself inserted this heading, with the first three lines of the printed details, in the manuscript copy. Neither the reference, nor the longer account of the variety (evidently a different species) appeared there.

C. caput-serpentis. C. obtusa triquetro-gibba, postice obtusiuscula.

"Fusis" was the earlier reading for "confertis."

C. Mauritiana. C. obtusa triquetro-gibba, postice depresso-acuta.

"Pet. Gaz. t. 96. f. 8. ex Insula Mauritii" was added in the manuscript: "fuscus" was the earlier version of "fusco-testaceus."

C. vitellus. C. subturbinata livida, maculis albis.

The published reference was substituted for "Bonan. 3. f. 254," a more characteristic figure: "maxima ex parte distincta, sed" followed "Spira." "Albida," not "alba," was the tint at first ascribed to the base.

C. mus. C. obtusa subovalis gibba cinerea, fascia longitudinali fusca.

Our author himself inserted the account of this species in the manuscript. Seba was not quoted. "Habitat in Carthagena" was appended to the description.

C. tigris. C. obtusa ovata, postice obtusa.

In the synonym of Rumphius, 36 is a misprint for 38: the erroneous reference to the H of Gualtieri was not in the copy, where "Pet. Gaz. t. 96. f. 7" was indicated as illustrative. The printed additions were "aut alba," "fusco-ferrugineis" (in lieu of "fuscis"), and "s. alba, quasi exarata; postice subcylindrica, truncata"; the previous words "Linea, &c." of that sentence were also absent from the original description, but had been inserted by the hand of Linnæus. "Postice" preceded "planiusculo," and "subviolaceo" followed "nitore."

C. lynx. C. oblongo-ovata, linea flavescente, postice acutiuscula.

No variety was mentioned in the written copy.

C. Isabella. C. obtusa cylindrica, extremitatibus luteis.

"Pet. Amb. t. 16. f. 16." was cited in the manuscript, where the final remark was wanting.

C. onyx. C. umbilicata, subtus fusca.

Neither of the synonyms was quoted in the copy.

C. succincta. C. umbilicata, labio interiore utraque extremitate rotundato.

The entire account of this shell (the C. bicincta of the MS.) was added to the copy by our author.

C. ziczac. C. umbilicata, subtus lutea punctis fuscis.

None of the cited figures were referred to in the original, where "interiore" stood in the place of the printed "utroque fusco."

C. hirundo. C. umbilicata, supra cærulescente.

"Sparsis", "s. fusca", "necnon macula, &c." were emendations of the press: "postice" preceded "fere marginato" in the original.

C. asellus. C. umbilicata alba, fasciis tribus fuscis.

"Pet. Amb. t. 16. f. 18." and "Pet. Gaz. t. 97. f. 11." were cited in the copy as illustrative.

C. cribraria. C. umbilicata, maculis albis.

"Margo" preceded "adscendens" in the copy, in which "livide flavo" was found in place of "luteo": "flavicantibus" was omitted. The intended name was C. Argiolus.

C. errones. C. umbilicata, macula testacea æquali.

Erratica was the original specific appellation.

C. moneta. C. marginate-nodosa.

"Pet. Gaz. t. 97. f. 8." and "Pet. Amb. t. 16. f. 8." were omitted in printing; "subflavescente" followed "convexo"; "subtus planiuscula" and "incisis" were absent. In place of the final remark (added, however, by the hand of our author), there originally stood "Noscitur tuberibus quinque elevatis."

C. annulus. C. marginata annulo flavo.

The "s. rotundata" was added in printing.

C. erosa. C. marginata flava albo-punctata.

"Undique aspersa" and "Macula fusca notat medium utriusque lateris" are the printed emendations.

C. helvola. C. marginata, postice crenata, subtus flava immaculata, supra albo punctulata.

The final remark was unwritten, and the size not mentioned: "marginis gibbi" was "margine exteriore gibbo", and "subcrenati" was "latere subcrenato."

C. stolida. C. marginata variegata cinereo testaceoque.

"Quinque" and "adspersis" were not in the original.

C. ocellata. C. marginata lutea, ocellis nigris.

C. flaveola. C. marginata fulva, albo punctata.

C. poraria. C. marginata subviolacea, albo punctata.

C. pediculus. C. transversim sulcata.

"List. 168. t. 3. f. 17." and "Barr. t. 1326. f. 28." were cited in addition to the printed synonyms. The last four words of the description were not in the copy.

C. nucleus. C. sulcata punctata tuberculis, rostrata.

"Pet. Amb. t. 16 f. 11." was cited as illustrative.

C. staphylæa. C. punctis elevatis sine striis, subrostrata.

The printed "minus" has been substituted for the earlier "vix"; "lutea" for "flava"; and "totam basin" for "maximum partem baseos."

C. globulus. C. rostrata lævis.

The printed additions were "alba s.", "extremitate utraque" (in place of "postice"), "Superficies punctis vix manifestis notata", and "excurrentes in strias".
