PEEFACE 



Parts 3,4, and 5 of Volume 1, Bulletin 82, include the systematic discussion of 

 the species and higher groups of living comatulids or unstalked crinoids. Part 3, 

 the present part, includes the account of the superfamily Comasterida, which covers 

 the single family Comasteridae. 



In the preparation of the present part I have been under special obligations 

 to Dr. Th. Mortensen, of the Zoological Museum, Copenhagen, who has sent me for 

 examination the magnificent collections which he made in the Kei and Philippine 

 Islands and elsewhere; to Dr. C. C. A. Monro, of the British Museum, who has sent 

 me all of the comatulids which have been received at the British Museum since my 

 last visit to that institution in 1910; to Dr. Torsten Gisl^n, of Uppsala, Sweden, 

 who sent me a series of specimens from the Bonin Islands; and to Mr. Edward J. 

 Holmes, of Boston. 



A complete index to all five parts of Volimie 1 will be found at the end of 

 Part 5.
