As лу111 be seen from the list of synonyms I quite agree with 

 Broch (1. с. 1911 p. 43) in joining together the three forms which 

 Kükenthal kept separate in his group "'Umbellata'\ with the sugge- 

 stion, however, that they possibly later might be united into one 

 species, an opinion which also Hickson (1. с 1907, p. 6) seems to 

 share. That in this case the specific name must be that given by 

 Rathke needs no further justification. 



E. florida has only been taken by the Carlsbergfond Ex- 

 pedition, and at the following localities: Turner Sound (69°45' N, 

 23°20' W), 3 fthms. -^/7 1900 (a single small specimen); Cape Tobin 

 (at the northern side of the entrance to Scoresby Sound, 70°23' N, 

 ca. 22° W), 57 fthms., ^^/s 1900 (2 well sized colonies, resp. 65 mm. 

 and 50 mm. high). 



This species seems to be arctic as well as boreal, but according 

 to the facts hitherto known its geographical distribution is consider- 

 ably more restricted than that of any of the preceding species, no 

 specimens having been taken east of the Kolafjord nor in any part 

 of the N. American arctic archipelago; it therefore seems doubtful, 

 if the species really should turn out to be circumpolar.
