COKRECTIONS AND ADDITIONS. 



The foregoing work was written three years ago, and the 

 first parts were then put into type. Consequently, there have 

 been many additions to the fauna, during this time, and, unfor- 

 tunately, some changes have been made in the nomenclature ; 

 besides this, the eggs of some species have since been discov- 

 ered. Thi-ough press of business, I have been largely depend- 

 ent upon proof-readers, who, although perfectly competent as 

 regards the general text, have, naturally, allowed some errors 

 in the Latin names to escape their attention. These are, in a 

 measure, corrected here.
