 Tills work has unfortunately not been accessible to me. I have had to use 



the extract from it found in Jones's "Manual of the Natural History, Geology and 

 Physics of Greenland and the Neighbouring Regions", 1875, p. 510. 



A more complete survey of the literature touching upon the echinoderms men- 

 tioned in this paper, will be found in "Fauna Aretica", published by ROmer & Schaudinn. 

 (See Nos. 7, 8, 12, 21 and 22 of the present list). In that work there will also be 

 found a complete account of the distribution of the species, and their synonyms
