Many of the forms already described are nevertheless little known and my endeavours 

 to fill these gaps of our knowledge, as far as I could, have greatly enlarged the scope of the 

 present work, not only because I tried to arrive at a survey, as complete as possible vvith the 

 means at my disposal, of all the Indo-Pacific, and partly also of the Atlantic, species, but also 

 because it proved necessary to figure, either for the first time or anew, a large part of the 

 "known" forms. 



Again it is a grateful task to me to thank Dr. J. G. de M.an for some good advice 

 and for the loan of rare papers, which otherwise would be inaccessible to me.
