14G Messrs. Parker, Junt.-.s, and Brady on 



uiifinislicd work, and the latter represents, in all, something 

 less than a score of species without arrangement or reference 

 to each other. 



In the ' Tableau Mdthodique,' however, not only are the 

 Foraniinifera separated (though on wrong grounds) from their 

 supposed congeners, but all the species knowni up to the time 

 of its publication are grouped in a perfectly intelligible though 

 artificial way. It is, in point of fact, a classified index to 

 about 550 species, with copious references to figures and de- 

 scriptions given by earlier A\Titcrs, and illustrated by seven 

 excellent plates of well-selected typical forms. 



In two previous papers (Parts X. and XII. of the present 

 series ; see Ann. Nat. Hist. Dec. 1863 and July 1865 respec- 

 tively) some portions of the ' Tableau ' have been critically 

 reviewed, namely : — 1st, the species (sixty' -three in number) 

 adopted from earlier authors, with four others named by 

 D'Orbigny from previously published figures (except Soldani's); 

 2ndly, the twenty-six species of which drawings are given in 

 tlie ])lates appended to the memoir (Ann. Sci. Xat. vol. vii. 

 plates 10-17*) ; and, 3rdly, species, a hundi-ed in number, 

 illustrated by models f- Our present task, the longest and 

 most difficult, perhaps also the most important, is to give the 

 result of a cntical examination of the species based upon the 

 figures in iSoldani's ' Testaceographia.' 



For reasons which will appear as we proceed, the Soldanian 

 forms named by D'Orbigny have never received proper re- 

 cognition from naturalists ; we are glad therefore to be able 

 to ap})end to the present synopsis a set of outlines, carefully 

 reduced from the figures in the ' Testaceographia ' refeiTcd to 

 in the ' Tableau Methodique,' which, as there is often a diffi- 

 culty in obtaining access to the originals, may form a useful 

 basis for future students. 



A few words at the outset on the work itself and its author 

 can scarcely be out of place. 



Of ISoldani's personal history we know but little, and that
