— 134. Strombus exustus, described by Lamarck (Syst. 7. p. 211) under tlie name 



of S. Papilio. The first of these names, however, has the right of 

 priority. (See Mus. Cal. 1797.) The figures of Martini, torn. 3. tab. 8. 

 f. 825, 8^6, clearly represent this species j 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 Cyeliow-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 An)er:c;i. 

 Latham's description of his yeliow-backed Warbler, I should think, is 

 not quite accurate ; as he only alludes to o,ie white bar on the wing 

 covers, whereas both Wilson and Vicillot say there are two.
