Echinodermata. 



(Supplement.) 



When examining the mollusca collected by the 2nd Fram Expedition 1 found 

 among them some echinodermata from localities not mentioned in the report on 

 echinodermata found during the expedition (Rep. II Norweg. Arctic Exp. in the 

 "Fram" 18981902 no. 13, 1907). One species, cucumaria minuta, is not even re- 

 corded in the report, and does not seem to have been previously found in the 

 waters about Jones Sound and Smith Sound. As a supplement therefore to the 

 report on the Echinodermata of the Frara Expedition I append a description of these 

 species. From the archipelago west and north of Baffin Bay we are, it would seem, 

 now acquainted with : 2 crinoids, 6 asteroids, 6 ophiuroids, 1 echinoid and 4 holo- 

 thurians.

 armed specimen with three of the arms fully developed and of
