NOTE 



IT is but just to the author to put on record the fact that the 

 MS. of the chapters on the Platyhelmia were written during 

 the years 1895-97; much of it was printed, and the proofs 

 corrected in 1897; and the whole of the Part was in proof, 

 and most of the figures were already prepared, early in 1898, 

 when the author left England for New Zealand. At the 

 same time the editor is satisfied that no important omissions 

 due to this fact occur in the hook, the proofs of which have 

 been revised and some additions made during the present year.
