Family EUCOPIIDAE 

 Eucopia grimaldii Nouvel, 1942 



This mysid is a moderately large bathypelagic 

 species that occurs most commonly at depths 

 of about 2,000 m and has not been found at less 

 than 300 m. Its nfeoKraphic distribution is cos- 

 mopolitan, it having- been reported from the 

 North and South Atlantic, Pacific, and Indian 

 Oceans. The majority of records are from tem- 

 loerate and tropical waters, but it has been re- 

 corded from as far north as Iceland and southern 

 Greenland and as far south as South Africa and 

 New Zealand (Fage, 1942; Tattersall, 1951). 



There is only one specimen of E. gthnaldii in 

 our collection (Burns and Wigley, Table 2). 

 taken at a dce|)\vater station (700 m) along the 

 continental slope off southern New England 

 (Figure 2). This siiecimen was caught in a 

 12.2-m shrimj) trawl equipijed with a coarse- 

 mesh (6.5 cm extension measure) net. Al- 

 though the net was fished on bottom, it cannot 

 be determined at what depth the specimen oc- 

 curred. The low fishing efiiciency of this trawl 

 during setting and retrieval, however, lends 

 support to the belief that it was caught on or 

 near the ocean bottom. 



This is only the second record of this species 

 from off the eastern coast of the United States, 

 even though it is moderately common in other 

 areas and widely distributed throughout the 

 world. Its occurrence in deej) water over bot- 

 tom sediments compo.sed of silts and clays is 

 typical for this species.
