The list of synonyms shows that I now unite U. Lindahlii with 

 U. encrinus, while in my report on the Ingolf-Pennatulids I thought 

 it convenient to distinguish two separate, although very closely re- 

 lated, species, the one characteristic of the "warm" the other of the 

 "cold" area of the northern Ocean. Since the publication of the 

 account mentioned I have had the opportunity to examine a large 

 number of Umbellulas, old ones as well as young, from Greenland 

 xuii. "" 38
