 that in the legends or explanations of the plates. Thus in this 

 work Rosalina berthdoti in the text is It. hcrthclotiana in the 

 plate ; and Nonionina stelligera in the text becomes N. stelliferct 

 in the plate. The name in the text, of course, stands. 



IX. — The South American Memoir. 



The " Voyage dans I'Amerique Meridionale " was the magnum 

 opus of d'Orbigny's life, in the sense that it was the only one of his 

 vast projected and commenced works which ever arrived at com- 

 pletion (see post, p. 59).^ There exists some confusion as to its 

 precise date, but as regards the section devoted to the Forami- 

 nifera it is certainly the last-issued of the 1839-40 Memoirs. In 

 a note on p. 1 he tells us that he published the Cuba, Canary 

 Islands, and Paris Basin Memoirs " last year." The Paris Basin 

 Memoir was read before the Societe Geologique de France on 

 December 2, 1839, and published in their " Memoires " in 1840. 

 There is little doubt, therefore, that this latter work was issued 

 early in 1840. In the month of June, 1840, Troschel published in 

 Wiegmann's " Archiv " a combined abstract and translation of the 

 Cuba, Canaries, and South American Memoirs, in which every 

 genus and species described in the three Memoirs are brought 

 together under their families ; he (Troschel) says himself : " It 

 seems to me most appropriate to bring together here all that is most 

 interesting out of all three works." - Messrs. Sherborn and 

 Woodward dealt with this vexed question in one of their many 

 Bibliographical notes,^ and agreed that for all practical purposes 

 1839 is the date to be assigned to this portion of the work. 



The publication of the entire work in seven volumes folio, with

 . . . 1833 par Alcide d'Orbigny . . . Ouvrage dedi^ au Roi et publie sous les

 Strasbourg (Levrault) ; 1839. 



- " Es scheint mir am Zweckmassigsteu das Interessanteste aus alien drei 

 genannten Arbeiten hier zusammenzustellen," Dr. Troschel. " Die Foraminiferen 

 Amerika's und der Canarischen Inseln von Alcide d'Orbigny." Im Auszuge mit- 

 getheilt von Dr. Troschel. In A. F. A. Wiegmann's Archiv fiir Naturgeschichte, 

 Jahrg. 6 (1840) pp. 398-462, Berlin. The last paper in the first half-yearly 

 volume. 



* " The title-page of the 'Foraminiferes' is dated 1839, the wrapper is dated 

 1843. Troschel in 1840 translated and printed the whole work. Apparently the 

 whole work was printed by the Government, and was ready for publication by 

 1839, but for some reason or other was delayed. The fact that Troschel re- 

 printed the paper, however, allows us to take the original date of 1889, rather 

 than to disturb the history of so many specific names." — C. Davies Sherborn 

 and B. B. Woodward, in Ann. Mag. Nat. Hist., ser. 7, vii., pp. 388-9.
