a report by Hubert Lyman Clark, entitled, " The Echinoderms 

 of the Woods Hole Region," published in 1904, in the Bulletin 

 of the United States Fish Commission for 1902. Many of the 

 species are described, with interesting observations on their 

 natural history, in Verrill and Smith's report on the " Inverte- 

 brate Animals of Vineyard Sound and Adjacent Waters," pub- 

 lished in 1874, in the Report of the Commissioner of Fish and 

 Fisheries. Other papers, which deal with particular species or 

 groups of species, are mentioned under the separate species, while 

 some of the more general treatises on the Echinoderms are in- 

 cluded in the Bibliography at the end of this report.
