COPEPODA. 



Copepoda were fairly numerous in Mr. Bruce's collection of 

 Pranz- Josef Land Crustacea. They represent a considerable 

 number of species, and two of them are freshwater forms. 

 Several of the species have been long known as denizens of the 

 Arctic seas ; but, on the other hand, this is the first time that a 

 large proportion of them have been recorded from such high 

 latitudes. Nearly all the Franz-Josef Land Copepoda belong to 

 described species, only a very few being new to science. Another 

 interesting point in regard to these Arctic Copepods is, that 

 while the majority of the pelagic forms — that is such as are 

 usually captured by tow-net — are of large size and belong to few 

 species, the majority of those taken with the dredge are small 

 and the species numerous. It may be remarked further that 

 in recording the species of Copepoda obtained in the Franz- 

 Josef Land collection, thofe belonging to the Calanidse are 

 placed first, then follow the Centropagidae, the Mesophriadse, the 

 Cyclopidae, the Harpacticidae, and the Oncseadse. The families 

 Centropagidae, Mesophriadse, and Oncseadse are each represented 

 by a single species, the Calanidse and the Cyclopidae by four 

 species each, and the Harpacticidae by 36 species, or 47 in all.

This species was fairly well represented in the Franz-Josef Land 

 collection ; it occurred chiefly in tow-net collections from the 

 vicinity of Cape Flora, Northbrook Island, as, for example, at 

 "West Bay; off" east end of Cape Gertrude ; two-thirds of a mile 

 south-west of Elmwood ; off West Glacier, and also near East 

 Glacier.

 junior and adult forms. Calanus Jiyperboreus was of rather more
