 Stat. 98 (77°N. 17V2°W.). 300 m. 1 specimen. 



The present specimen is of the typical form, closely resembling 



the excellent figure given by Döder- 

 lein (Taf. IV. Fig. 1). 



While, as pointed out by Döderlein 

 (Op. cit. p. 205), the spines of this spe- 

 cies do not carrj^ pedicellariæ-bundles, 

 as is otherwise generally the case in 

 this genus, the spines sometimes pre- 

 sent a sort of appendages, which, 

 on a superficial examination, might be 

 taken to be straight pedicellariæ. It is, 

 however, only a sort of branching 

 of the spine; but the skeleton of the 

 branch lies loose in the skin, without 

 any direct connection with the skeleton 

 of the spine itself and there is no trace 

 of such a connection ever having 

 existed (Fig. 4). It is thus a sort of 

 "false ramification".
