BIBLIOGRArHY.

Library of the Geological Department fortunately possesses Livraisons 

 nos. 1-12, stitched in their original covers, the dates of which are altogether 

 at variance with those cited by Bayan. The information connected with the 

 remainder of the dates has been procured from reviews and notices occurring 

 in the undermentioned works : — 



Fgrussac's Bull. Sci. Nat., 1826, vol. 8. pp. 133, 134. 



„ „ „ 1830, vol. 20. p. 340.

After a large amount of research I am able to present the following as a 

 fairly accurate statement of the dates required. The plates were published 

 simultaneously with the text, so that only paginations are given : —
