12 G. 0. SARS. CRUSTACEA. [norw. pol. exp. 



28th June, 1895. 



84° 32' N. Lat., 76° E. Long. 



About midway in the route of the 'Fram'. 



Sample taken by towing from a boat in a large open lane in the ice. 



Parathemisto ohlivia, (Kroyer). 



Calanus finmarchicus, (Gunn.). 



— hyperhoreus, Kr. 

 Scaphocalanus acrocephalus, G. 0. Sars. 

 Undinella oblonga, G. 0. Sars. 

 Euchosta norvegica, Boeck. 



Chiridius armatus, (Boeck). 



— tenuispinus, G. 0. Sars. 

 Heterochoeta norvegica, Boeck. 



— compacta, G. 0. Sars. 



Metridia longa, (Lubb.). 

 Temorites hrevis, G. 0. Sars. 



Conchoecia maxima, Brady & Norm. 

 Sagitta (Spadella). 

 No algae. 



Of the 11 species of Copepoda enumerated from the above-named sample, 

 6 also occur off the Norwegian coast; but it is worthy of note, that all of 

 them, except Calanus finmarchicus, are here confined to great depths, 

 more than 100 fathoms. The above-named Hyperiid, Parathemisto ohlivia, 

 is also a pronounced deep-water form off our coasts, and the same is also the 

 case with the 3 Norwegian species of Conchoecia, one of which, C. horealis 

 G. 0. Sars, is very closely aUied to the arctic form here named. 



In the following pages, I shall try to give an account of all the species 

 of Crustacea found in the collections of the 'Fram', with notes on their 

 occurrence and distribution, and with descriptions and figures of the new or 

 less familiar forms. 



The plates accompanying this account have been prepared by the auto- 

 graphic method employed by the present author in most of his recent publi- 

 cations, and will, I hope, serve for an immediate recognition of the species.
