works : are not uncommon, especially in the case of French works 

 issued in livraisons. 



The " Didot " or Plassan edition disposed of, it becomes 

 necessary to determine the original place of publication of the 

 tableaux. Mr. Sherborn quotes from Engelmann (Bibl. Hist. 

 Nat., 1846, 376) a tract " in-4. Paris. an VII. (1799). 

 Plassan. (38 pag.)," supposed to contain these papers, 2 but waiv- 

 ing this as inaccessible and doubtful, the earliest published 

 reference, in the case of the bird portion, appears to be Daudin's 

 'Traite,' Vol. I, 8 Jan. 1800 (422-438). Here the principal bird 

 classifications from Johnston, 1657, to Lacepede, 1799, are shown, 

 with more or less detail, giving in each instance the name of 

 the author and work from which it was extracted. Lacepede's 

 tableau (in full, but differing in some details from that of 1801), 

 however, is cited simply as " Methode de Lacepede, 1799," 

 indicating apparently that it was previously unpublished. Hav- 

 ing been read before the Institute June 9, 1799, 't was undoubt- 

 edly accessible to Daudin. The specimens in the Paris Museum 

 were at that time arranged, and no doubt labelled according to 

 the tableau. (Cf. Daudin, Traite, I, 35.) 



The various genera in our Check-list credited to Lacepede, 180 1, 

 and others to Cuvier, Lecons d'Anat. Comp. 1, 4 should properly 

 be quoted " Lacepede, in Daudin, Traite," etc. 



In order to render the dates of publication of the Plassan 



1 Byron's Narrative of the voyage of the ' Blonde,' dated 1826, was publ. 

 Feb. 20, 1827 ; the Appendix to Parry's 2nd voyage, dated 1S25, was publ. 

 in Feb., 1827 ; Swains. & Rich. Fauna Boreali-Americana, II, dated 1831, was 

 publ. in Feb., 1832. 



With French works it was often the practice to issue the title page, table of 

 contents, etc. in the first livraison ; among antedated works may be noticed 

 Vieillot's Ois. Am. Sept., dated 1S07, but published in 22 livraisons, of which 

 the first was issued Dec. 1, 1S07 ! — The Zoology of the voyage of the ' Ura- 

 nie'& ' Physicienne,' dated 1S24, was published in 16 livraisons, the last in 

 June, 1826, etc. 



2 There is no mention of such a tract in the Journ. Typ. for the year 1799. 



3 Announced in the Journ. Typ., Jan. 19, 1S00. Giebel (Orn. Thesaurus, 

 I, 1872, 3), for some reason, gives it as " 1799." 



4 Published in April, 1800 (Journ. Typ. Apr. 19, 1800).
