Note. The abbreviations of separate works are readily recognizable, 

 and do not require explanation. Memoirs that appeared in serials are 

 always quoted from such serials, with one or two exceptions, like Pomel's 

 ' Catalogue Me"thodique ' 1 (Paris, 1853) and H. von Meyer's ' Die fossile 

 Zahne und Knochen von Georgensmund ' (Stuttgart, 1834), which ori- 

 ginally appeared in serials but are better known as separate volumes. 



1 The first part of this Catalogue appeared in its original form in 1852, in 

 the ' Ann. Sci. Auvergne ' ( Clermont-Ferrand).
