and pseud- to earlier specific names, and claiming them as new 

 d'Orbignyan species — thus : Textularia suh-elongata d'Orb. for 

 T. elongata Cornuel/ Fr07idic'ularia 'pseudo-ovata d'Orb. for F. ovata 

 Phil.'-^ It will be readily appreciated that any reference to the 

 " Prodrome " in synonymies, though often justifiable and valuable, 

 must be made with very great care. It must also be borne in 

 mind that his new family Cyclostegues (see ante, p._26) appeared 

 and disappeared with this work.^ 



It was d'Orbigny's announced intention ^ to issue a yearly 

 Supplement to the " Prodrome," and he begged authors of papers 

 on the MolJusca^nd Eadiata to give him notice of their papers to 

 that end. No such Supplement, however, was ever issued, a 

 failure of an "intention which, how^ever praiseworthy in itself, one 

 cannot help being thankful was never realized. 



Immediately after the publication of vol. iii. of the " Prodrome " 

 in 1852, the second volume of the " Cours Elementaire " made its 

 appearance. We need not refer to any other section than that 

 devoted to the Foraminifera (p. 189), where they are placed as 

 the second division of the Zoophytes — " Zooj)hytes Globuleux." 

 This section is mainly interesting as containing his latest expressed 

 views upon the group. The general introduction, which is very 

 short, is a condensation of that in the Vienna Memoir, and the 

 text is an analysis of genera only, no species being named, excepting 

 in the legends to the seventeen woodcuts which illustrate it. Of 

 these, eleven are reproduced from the Vienna, one from the Paris, 

 and one from the South American Memoirs. The figures, which 

 are new so far as d'Orbigny's work is concerned, are : —

p. 689, fig. 557).^ 

 „ 318. Marginulina harpula (repeated at p. 475, fig, 427). 

 „ 322. Nummulitcs plamdata (of which the middle figure 



appears to be an Anomalina). ^

- XV., vol. iii., p. 153. Not to multiply instances, I may refer to Dentalina 

 striata d'Orb., 1826, which is ignored by Sherborn, but is claimed by d'Orbigny 

 here (vol. iii., p. 152) as the original, and therefore the correct name of Nodosaria 

 acicula (Phil., 1844). ^ See XVII., pp. 7, 105. ' XV., p. Ix. 



^ The genus Orbitoides was first instituted by d'Orbigny in 1847 for the recep- 

 tion of a peculiar fossil brought from the United States by Sir C. Lyell, who had 

 noticed it (Q.J. Geol. Soc, iv., p. 12) under the name of Nummtdites mantelli 

 previously conferred upon it by its discoverer Morton. I have not, however, been 

 able to discovt r that d'Orbigny gave any definition of the genus previously to the 

 publication of the second volume of his " Prodrome," in which he characterizes it 

 by a portion of the de cription which he afterwards more fully gave in his " Cours 

 Elementaire," ii., p. 194 (XVIL, p. 298). See Appendix P., note. 



'^ It might equally be taken to be identical with his Rotalina voltziana, of the 

 Paris Chalk Memoir (pi. ii., fig. 33). 



^ The figures which inake up tlie composite illustration of this species are very 

 iamiliar, the vertical section having done duty in many works both before and since
