PREFACE. 
Part of the following Report was published at an earlier date, with kind permission of 
Prof. Dr. Max Weber, — viz. the results of the investigation of the subgenus Eucirripathes. 
I am very much indebted to my sister Mrs. L. Wap-van Pesch for the tiresome work 
of reading through and correcting my English translation of the manuscript. 
January 1914. 
A. J. van Pesch.
