2 BULLETIN 76, UNITED STATES NATIONAL MUSEUM 



of Bell's Cdhxuterias aniipodum and Sladen's Calvasterias stolidota and has supplied 

 information concerning essential anatomical details, omitted by the describers. 



From acknowledgments to many colleagues who have directly or indirectly 

 aided my work it is to be hoped I have made no serious omissions in the introductory 

 paragraphs to parts 1 and 2. It is a truism not too often repeated that no serious 

 piece of scientific work can be completed without the cooperation of others. 



In bringing this monograph to a close it is perhaps permitted one to indulge in 

 the pleasant retrospect of personal contacts and to record the hearty cooperation of 

 the staff of the United States National Museum which has been more formally 

 alluded to in the foregoing parts. The late Dr. Richard Rathbun, then assistant 

 secretary of the Smithsonian Institution, always evinced a lively interest in the 

 progress of this report — an interest which has happily been continued by his suc- 

 ceesor, Dr. A. Wetmore. Nor should I forget, in matters taxonomic, the wise deci- 

 sions of such experienced experts as Dr. Theodore Gill and Dr. Leonhard Stejneger; 

 nor in matters of book making, the seasoned counsel of the editor, Dr. Marcus 

 Benjamin, cheerfully tendered for over a score of years. 



The retrospect, coming nearer home, inevitably focuses on the late Dr. Charles 

 Henry Gilbert, long professor of Zoology at Stanford University. A scientist of 

 unusual talents and a controlled and logical mind, he followed to the letter the 

 Bairdian precept that what is worth doing is worth doing well. To him as professor, 

 colleague, and friend, I owe much, as well as to our mutual professor, colleague, and 

 friend, the venerable Dr. David Starr Jordan. But for their confidence the present 

 monograph — and others — would have been the pleasant task of another.
