The Crustacea and the Mouuusca have been already 
mentioned under the list of localities (p. 79). Finally 
the TunicatTa form a large collection of from 25 to 30 
species represented by several hundred specimens. I am 
now examining them in detail with the assistance of Miss 
J. H. Willmer. As we are going over every specimen 
with the view of determining the variations, and as Canon 
Norman has kindly sent me the collection of Ascidians he 
made last year in Finmark in order that they might be 
examined along with the “Argo” specimens, it will be 
some weeks before the descriptions and drawings are 
finished. Consequently as it is desirable that this general 
account of the results of the ‘‘ Argo”’ cruise should not be 
further delayed, I shall give here a preliminary list of the 
Tunicata so far as they have yet been identified, leaving 
the detailed account for a separate report, like that on the 
Sponges by Dr. Hanitsch.
