ADDENDA ET CORRIGENDA.

In the Systematic Index, Conchology, Part I. for "Acephalis" read "Acéphales."
Pl. 92.page 1. line 13, for "caudi," read "caudis."
page 1. line 23, for "Dentatis" read "Dentati."
— 3. — 11 from the bottom, for "Lepidopteræ" read "Lepidoptera."
— 102.Add to the Synonyms, A. virginea. Lamarck. Syst. tom. 6. part 2. p. 131. Sowerby's Genera. Achatina, f. 2.
— 124.last line, for "female" read "male;" and in the line above, for "male" read "female."
— 125.for "P. Nireus" read "P. Nerius."
— 126.Add to the Syn. Lam. Syst. 7. p. 467. 55; and for Ency. Meth. pl. 326. f. 204., read pl. 326. fig. 2 and 4.
— 127.Add to the Syn. Lam. Syst. 7. p. 465. 50.
— 134.Strombus exustus, described by Lamarck (Syst. 7. p. 211) under the name of S. Papilio. The first of these names, however, has the right of priority. (See Mus. Cal. 1797.) The figures of Martini, tom. 3. tab. 8. f. 825, 826, clearly represent this species; although Lamarck has quoted them for S. lentiginosus.
Strombus lentiginosus. Add to the Synonyms, Lam. Syst. 7. p. 203. Knorr, 3. tab. 13, f. 2. Lamarck has omitted to quote any of the figures representing the young shells of this and the following species.
— 135.St. tricornis. Add to the Syn. Lam. Syst. 7. p. 201.
— 139.Sylvia plumbea. This bird greatly resembles the female of S. pusilla of Wilson (yellow-backed Warbler, Latham), yet differs in having the belly golden yellow instead of white: I was told, moreover, that this was a male bird: the one inhabits North, and the other South America. Latham's description of his yellow-backed Warbler, I should think, is not quite accurate; as he only alludes to one white bar on the wing covers, whereas both Wilson and Vieillot say there are two.
— 145.Eburna tessellata. Add to the Syn. E. Arcolata, Lam. Syst. 7. p. 282. 4.
— 146.Eburna Pacifica. Add to the Syn. E. lutosa? Lam. Syst. 7. 282. 5.
— 150.The upper figure is of Sphinx Leachii, and the under of S. fasciata.
— 152.Add to the Syn. Helix regina. Ferussac Moll. liv. 19. pl. 119.
— 153.Ditto S. bituberculatus, Lam. Syst. 7. p. 202. 6.
— 157.Amp. Effusa. Ditto, Lam. Syst. 6. 2. p. 178. 5.
— 164.Add to the Syn. Le Figuier Tcheric, Le Vaill. Ois. d'Af. 3. pl. 132.
— 166.Ditto Lam. Syst. 6. 2. p. 178. 5.
— 170.Ditto Le Vaill. Ois. d'Af. 3. pl. 112. f. 2.
— 177.Ditto Pyrula Spirillus. Lam. Syst. 7. p. 142.
