42 JAMES A. GRIEG. [SEC. ARCT. EXP. FRAM 
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” 1898—1902 no. 18, 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 Fram 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.
