Forsblad Fjord, 90 — 50 fathoms, 2 specimens. 



These two specimens differ rather much. In one the adam- 

 bulacral spines are mostly disposed in single transverse series, 

 their number varying from 3 to 6 ; here and there a single 

 spinelet is found in the ambulacral groove, reminding of Cr. sang- 

 uinolenta. — In the other specimen the adambulacral spines 

 are disposed in double transverse series, very crowded, espe- 

 cially at the oral end of the groove. The marginal plates are 

 very distinct in this specimen and the larger tubercles on the 

 abactinal side rather numerous. The one of these specimens 

 thus unites two of the most important characters of the Var. 

 tuberculata Dan. Kor. : the distinct marginal plates and the nu- 

 merous tubercles of the abactinal side, with the disposition of 

 the adambulacral spines found in the typical form, whereas the 

 other specimen has the adambulacral spines disposed as in the 

 Var. tuberculata^ but no marginal plates and very indistinct 

 tubercles on the abactinal side. The Var. tuberculata Dan. Kor. 

 thus evidently cannot be maintained as a distinct variety — as 

 also results from the researches of Doderlein and Levinsen.

Hurry Inlet, 50 fathoms (Clay with stones). One specimen, 

 agreeing perfectly with the descriptions given by Verr i 11 and 



In a recently published paper (Oversigt over det nordlige Norges Echi- 

 modermer. Bergens Museum Aarbog 1902 p. 28). J. A. Grieg states the 

 Echinaster scrobiculattis to be only a young stage of Cr. sanguinolenta.
