108 Rev. Canon Norman on the Marine 



X. — Notes on the Marine Crustacea Ostracoda of Norway. 

 By the Rev. Canon A. M. Norman, M.A., D.C.L., 

 F.R.S., &c. 



During a dredgmg-expedition undertaken this last summer In 

 East Finmark I explored the Varanger Fiord, and especially 

 the fiords which run inland on its southern side close to the 

 Russian frontier. Several arctic Ostracoda were here added 

 to the Norwegian fauna, and the range of many species ex- 

 tended northwards. In noticing the species of this district I 

 have thought it well to bring together the results of my former 

 expeditions in 1878, 1879, and 1882 to the Norwegian coast, 

 though most of the localities of the species belonging to the 

 section Podocopa have been previously published in Pro- 

 fessor Brady's and my recent monograph *. Since the 

 publication of that work Prof. Gr. O. Sars has published f 

 a revised list of the Norwegian species of this order, with 

 descriptions of new species ; but these latter do not embrace 

 any marine forms. At the end of this paper I have added a 

 list of twenty -three species which have been found by him 

 and not by myself, and these, added to the ninety-five which 

 J here record, give us one hundred and eighteen marine 

 Ostracoda at present known in the Norwegian seas. 



As it appears to me that we have now sufficient knowledge 

 respecting the distribution of most of the species to enable us 

 to approximately divide them into arctic, boreal, and abyssal 

 forms, I have attempted to do this at the close of the paper. 

 At the same time it cannot be doubted that more extended 

 investigation in the future will lead to much modification of 

 the assigned origin here given of species, though upon the 

 v.hole it will, I think, as far as it goes, prove to be fairly 

 correct. 



The synonyms I have added are not the names now 

 employed by Prof. G. O. Sars, but those under which he 

 described the species in his monograph ' Oversigt af Norges 

 marine Ostracoder,' published in 1865.
