B. PERDIX. _B._ umbilicatum subsulcatum, basi recta. The proposed name was _B. pennatum_, adopted from Rumphius: "lunari-patula" was not in the manuscript. B. POMUM. _B._ exumbilicatum, labio utroque dentato. "Barr. Ic. t. 1325. f. 12" (cited in the 'Systema'), and "Klein, 95. Semicassis, striata, costosa", were the additional synonyms of the manuscript: "s. sulcata", "nullum, interne", "at vero in adultioribus accrescit planum album", were subsequent emendations. B. DOLIUM. _B._ emarginatum subsulcatum rugosum, labio exteriore reflexo dentato. The _Dolium fimbriatum_, or, as Deshayes prefers it, _D. Minjac_ (the Malay name was Bia Minjac in Rumphius, who preceded Adanson), was assuredly the shell described in the 'Museum', as the recorded dentation of the outer lip clearly manifests. An excellent figure of it in Petiver ("Gaz. t. 99. f. 11") was cited in the original copy, where the drawing of Gualtieri was not referred to. B. ECHINOPHORUM. _B._ (changed to _Cassida_) tuberibus ("quaterna serie" interpolated) nodosum. The reference to Rumphius was correctly written 1, not I, in the original, where "albido-flavescens" was the indicated colouring. The printed emendations were "quadruplici s. quintuplici", instead of "triplici", and the entire account of the aperture, which at first ran simply as follows, "Labium exterius crassius, margine tenuiore, interne subrugosum, obsolete dentatum." B. TUBEROSUM. _B._ tuberibus gemina serie nodosum. The entire published account of this species had been interpolated by Linnæus in the written copy, with the exception of the "color pallidus." The "nodis anterioribus" was a misprint for "nodis acutioribus." Gualtieri's admirable figure of the _Cassis tuberosa_ of authors was not, however, cited, which confirms my statement that the species of the 'Museum' was not the _Cassis_ usually so designated. B. CORNUTUM. _Cas._ acuminibus antice cingentibus, superficic reticulata. The I in the reference to Rumphius was a misprint for the written 1: "maculata" was originally "maculis griseis." B. RUFUM. _Cas._ nodis sparsis. "Pyri" was a misprint for the written "pugni". Neither the "maculis fuscis" nor the "Variat tota albo colore" were originally present. The Rumphian name _rubra_ was the one written. B. FLAMMEUM. _Cas._ longitudinaliter striata, antice subnodosa. To the solitary synonym our author had added "List. t. 1004. f. 69" and "Sloan. Hist. 2. p. 242. n. 2". The final remark was not in the copy. B. TESTICULUS. _Cas._ lævis, striis longitudinalibus, sulcis transversalibus. "Vix ullus" was at first "nullus": "læve" was not present. B. DECUSSATUM. _Cas._ lævis, striis decussatis, labio exteriore dentato. "Bonan. Clas. 3. t. 157" was an additional synonym. B. AREOLA. _Cas._ glabra, spira papillosa. The erroneous references to Gualtieri, and to the figure 2 of Rumphius, were not present in the original, nor was there any allusion made to the sculpture of the inner lip.
