[Published in twenty-six fascicules ; the first twenty-five under the title: 
‘*Ostéographie ; ou, description iconographique comparée du squelette et du 
systeme dentaire des cing classes d’animaux vertébrés récents et fossiles, pour

The twenty-sixth and last fascicule was issued with the speczal title above 
given, titles for the four volumes of text and four of plates, table of contents 
and index, by the Bailliéres in 1864. The subscription price was 2 frances 35 
centimes per plate; the price of the twenty-sixth livraison, 45 franes; and of 
the whole, on completion, 800 francs, ‘‘ au lieu de 961 fr.” 
The culpable neglect of the publishers to give the dates of publication of the 
several fascicules has doubtless devolved upon many investigators, as upon the 
writer, much trouble and annoyance in ascertaining them, and to save to 
others similar trouble, a collation is here presented, the dates having chiefly 
been ascertained from Wagner’s annual reports in the ‘* Archiv fiir Natur- 
geschichte.”” The appearance of successive fascicules has not been noticed in 
the ‘‘ Bibliographie de la France.”’ 
The titles of the respective monographs given below are those at the upper 
fourth of the first page of each monograph, and which are the only special 
titles published. 
The work is more remarkable as a methodical repertcry of facts respecting 
superficial osteological details, than as a digest exhibiting acute appreciation of 
the value and subordination of characters and their taxonomical application.
