"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.
