HYHROIDA II 



We have thus reached a total of 91 species certainly known. The nature of the additions is 

 not uninfluenced by the fact that the investigations were largely carried out on the deeper slopes of 

 the coastal banks, so that southern and eurytherm species form the majority of the species thus added 

 to the fauna list of the island. 



We now come to the fauna of the Faroe Islands area. The species from here which are included 

 in the material cover the entire range of our present knowledge as to the hydroid fauna of this sec- 

 tion. We have here the following 57 species:

Along the deepest portions of the slope of the banks, the following five were found: Tubularia 

 regalzs, Corymorpha glacialis, Corymorpha groenlandica, Lictorella pinnata, and Serlularella mirabilis; 



save for the last but one, all of these belong to the cold area; finds lie so far out in the peripherv 

 that it is doubtful whether they should really be counted as belonging to the fauna of the Faroe 

 Bank. If we do so, then we have up to now 62 species recorded from the Faroe Islands sec- 

 tion, but the number will doubtless be increased by further study. We must at any rate expect to 

 find the following six species at the Faroe Islands, since they are found, and partly also frequent, iu 

 Iceland waters and round the British Isles: Cory ne Sarsii, Corymorpha nutans, Hydraciinia rchinafa, 

 ( uspidella humilis, Plumularia setacea, and Diphasia a/tcnuata. This, however probablv bv no means 

 exhausts the list of species, and in particular we may expect to find more southern forms as more 

 or less sporadic visitors to the Faroe Islands. 



A comparison between the fauna of the three areas shows that the Greenland area includes 

 11 species not known from Iceland or the Faroe Islands. These are:
