Mr. W. Small on Annelida Polycliceta 



regarded as Biilisli. The British Association Committee 

 defined the British Marine Area as consisting of a shallow- 

 water district bounded by the 100-fathom line and a British 

 Atlantic-slope district, or deep-water district, extending off 

 our western and nortlicrn shores from tlie 100-fathom line to 

 the 1000-fathom line, ?'. e. to tlie boundary of the continental 

 ])lateau. This arrangement includes the " cold area " or 

 Faroe Channel in British waters. Canon Norman's recom- 

 mendation to exclude this part from the British Marine Area 

 seems based on natural grounds. It is well known that 

 many forms occur on the ridge between the Faroe and 

 Shetland Islands which are not found in adjacent and deeper 

 waters or to the south. 



In the present Report, the Faroe Channel will be found to 

 have yielded annelids, e. g. Euiioa tritotii, M'lntosh, and 

 Euplirosyne hurealis, Q^]rstedt, which are not recorded from 

 the North Sea. Thcs'. forms may therefore be regarded as 

 arctic, and, if so, should be excluded from the British marine 

 fauna. 



Lists of synonyms liave not been given. They can be 

 got from Professor M'Intosh's monograph (1900) under the 

 heads of the various species, and they occupy a considerable 

 amount of space. 



I have to thank Prof. D'Arcy W. Thompson for his courtesy 

 in handing over the collection for examination and for pro- 

 viding a list of stations. I have also had the advantage of a 

 typical series of slides of each group from Prof. M'Intosh's 

 collection. 



Family Amphinomidap. 



Subfamily Eupsrosyninm. 



Genus EUPHROSYNE, Savigny, 1820. 



Eiiphrosyne horealis, Q^rstedt, 1843. 



Two specimens of this form were dredged along with 

 Eiinoa tritoni, MT., JSepJithys cceca, O. F. M., and Serpulids 

 in the Faroe Channel in 545-788 m. during the month of 

 June. These are the sole representatives of the genus 

 Euphrosyne and of the family Amphinomida?. Their scarcity 

 is not surprising, for these forms prefer a littoral habitat. Of 

 the two species of Euphrosyne obtained by the H.^hallenger ' 

 Expedition, one, E. capen&is, Kinberg, was found between 

 tide-marks, and the other, E. horealis, in 85 fathoms. The 

 present species would appear to have a preference for deeper 

 water.
