GENERAL CATALOGUE. 



N.B. In the following catalogue I .have not considered it necessary to 

 indicate which of the species have been found subf ossilized, except in those 

 particular instances where they have been observed only in that state, 

 under which circumstances they must be looked upon practically as extinct. 

 The names of those in this latter predicament have not only an asterisk (*) 

 prefixed to them, but are also printed in italics.
