PREFACE. 



Shortly after I began the study of the recent crinoids Drs. W. 

 Wehner and R. Hartmeyer of the Museum fiir Naturkunde offered 

 me for study the collection which had been brought together by the 

 German steamer Gazelle on her memorable voyage in 1874-1876. 

 When the work on this material was completed these gentlemen 

 most generously offered me the entire collection of their museum, 

 which was sent to Washington in order that I might compare the 

 specimens directly with those in the collection of the United States 

 National Museum. The debt of gratitude which I owe to Drs. 

 Weltner and Hartmeyer for their kindness can only be appreciated 

 when it is remembered that the collection includes the types of 

 many of the species described by Prof. Johannes Miiller in 1841 and 

 1849, and by Dr. Clemens Hartlaub in 1890. 



During the summer of 1910 I visited Berhn and examined the few 

 specimens wliich had not been sent to me, and also some others which 

 had been recently received. 



The Museum fiir Naturkunde has generously permitted tiie United 

 States National Museum to retain a number of the specimens belong- 

 ing to tlieir collection, and to have photographs made of all the 

 specimens of particular interest. 



The species represented by the specimens retained, and the local- 

 ities, are the following:
