144 CRUSTACEA MALACOSTRACA. III. 



of the rami of the uropods, and by the totally different shape of the abdominal operculum both in 

 male and female. But I have been unable to find any difference excepting in size between specimens 

 from the warm and from the cold area. - The differences between E. inermis and E. Hanseni are 

 pointed out later on. 



Occurrence. Taken by the "Ingolf" at five stations in the warm and nine in the cold area. 

 Davis Strait: Stat 35: Lat 65i6' N., Long. 55O5' W., 362 fath., temp. 3-6; 9 spec.

Stat. 119: Lat. 6753' N., Long. ioi9' W.. 1010 fath., temp. -4- ro; 2 spec. 

 South of Jan Mayen: Stat. 117: Lat og ^' N., Long. 823' W., 1003 fath., temp, -i- ro; ab. 18 spec. 



Stat 116: Lat. 7OO5' N., Long. 826' W., 371 fath., temp. -1-0-4; 10 spec. 

 Besides, this species has been taken by the "Thor" at two places in the warm area. 

 South-West of the Faeroes: Lat 6ii7' N., Long. 93o' W., 443 fath.; 5 spec. 



Lat 6ii5' N., Long. 935' W., 463 515 fath.; ab. 15 spec. 



Distribution. E. inermis has not been separated from E. cornuta by Sars, and I am sure 

 that his animals from at least several of the nine stations in the cold area enumerated by him in 1886 

 as belonging to E. cornuta in reality are E. inermis] some of his specimens from the deepest stations 

 may belong to E. Hanseni. It is probable that the specimens from the Kara Sea referred by Stux- 

 berg to E. cornuta belong to E. inermis; whether some or all of the above-mentioned specimens referred 

 by Grieg to E. cornuta belong to this species or to E. inermis cannot be guessed. 



E. inermis certainly lives at the bottom, as, in spite of its considerable size, it has not been 

 taken by the "Thor" in the young-fish trawl when this instrument did not touch the bottom. The 

 list shows it to have been found from 293 to 1010 fathoms and to be widely distributed both in the 

 warm and the cold area.

Description. Similar and closely allied to E. inermis in size, general appearance, and most 

 features. The front area (fig. 3 a) between the basal joints of the antennulee is, seen somewhat from 

 the side, horizontal to the end as in E. cornuta, but longer than in this species, consequently very
