II. AMPHIPODA AND ISOPODA, WITH DESCRIPTIONS 

 OF TWO NEW SPECIES. 



By W. M. Tattersall, M.Sc. 



During the examination of a small collection of Amphipoda and 

 Isopoda made by Dr. Wolfenden in the course of various cruises in 

 the eastern part of the Atlantic, between the Faeroe Islands and the 

 Azores, the two new species here described were met with. They 

 are both deep-water forms of great interest, the Amphipod of true 

 bottom-haunting habits, the Isopod more probably belonging to the 

 bathypelagic fauna of the ocean. 



In addition to these new forms, several interesting species, which, 

 however, do not call for more than brief notice here, were found in 

 the collection. Among the Amphipoda may be mentioned a remark- 

 ably fine specimen of Mimonectes Loveni, 1 Bovallius ; two examples of 

 Lycceopsis Lindbergi, 2 Bovallius, a species not taken again since its 

 description by Bovallius in 1889 3 ; Katius obesusf Chevreux, recently 

 described 5 from the collections of the Prince of Monaco, and since 

 rediscovered in deep water off the west coast of Ireland 6 ; and a 

 magnificent specimen of (Ediceros saginatus? Kroyer, measuring 

 26 millimetres, a length 6 millimetres in excess of that given for the 

 species by G. 0. Sars in his work on the ' Amphipoda of Norway.' 

 Among the more noteworthy of the Isopoda may be noticed Arcturella
