GENEBAL CATALOGUE 



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

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

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

 under which circumstances tliey 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.
