NOTE. 



By reason of an unfortunate misunderstanding, the proof-sheets of 

 pages 243-270 were not submitted to the author for revision. This over- 

 sight has resulted in the admission of a number of unpleasant inaccu- 

 racies of punctuation, particularly in the generic and subgeneric names;; 

 and furthermore has rendered necessary the insertion of the following, 

 list of
