CRI'STACEA MALACOSTRACA. III.

ilitfi-rent from that in /'. inermis; the anterior end is emarginate and protrudes freely and considerablv 

 above the base of the clypens. The basal joint of the antenuulsc (fig- 3b) differs much in shape 

 .1 that in E. comttia or E. inermu; the inner margin is even slightly longer than the breadth of 

 the joint, as the anterior inner part is produced into a large, triangular lobe which is a little longer 

 than broad and twice as long as in the last-named species; second and third joints mainly as in / 

 tnrrmis. - - The antennal squama (fig. 3 c) is longer and more narrow than in / in, nun. being some- 

 what more than half as long as the breadth of third joint 



The thoracic epimera, the uropods (fig. 3 e), the female operculum and the lateral plates of the 

 male operculum do not afford any valuable specific difference from /:. tin rnn\. Judging from my single 

 male the median lamella of its operculum has the terminal lol>es shorter than broad (fig. $A\ thus 

 considerably shorter than in /-.'. inermis. 



Length of the largest female, without marsupium (from StaL 113), 10 mm., of the single male 

 nin. 



Remarks. E. Hanseni is easily distinguished from E. inrrmis by the shape of the anterior 

 part of the front area, from both /:'. cornula and /:". incrmis by the very long lobe from first antennular 

 joint, from E. tornuta besides by the widely different shape of the abdominal operculum in both sexes. 



Occurrence. Taken by the "Ingolf 1 at four stations of the deeper part of the cold area. 



But of Iceland: StaL 105: Lat 65=34' N M Long. j $i' W., 762 fath., temp. -j-o-8"; 3 spec, (small).

(large). 



Distribution. Uhlin recorded it from a place nearly midway between Kast Greenland and 

 southern Spitsbergen, viz. at Lat. 7752* N., Long. 3s' W n 1460 fath., temp. ~ 1-4, and from west of 

 Horn Sound, West Spitzbergen, LaL /636' N., Long. I2io' E., 929 fath. - Certainly some of the deep- 

 sea specimens of Sars' specimens of E. cornuta from the Norw. North-Atlantic Hxped. (comp. p. 142) 

 belong to E. Hansrni, which evidently is a cold water form inhabiting from considerable to very 

 great depths.

The species has been elaborately described and on the whole sufficiently figured by Bonnier; 

 some features may yet be mentioned and a few figures added. 



The front area (fig. 4 a and 4 b) differs from that in /:. cornula in being distinctly broader with 

 the end very deeply incised; the incision is rounded at the bottom and the processes limiting it are 

 about as long as broad, triangular, very acute. - The first joint of the antenuula: at least frequently 

 broader than long, and it differs from that in /:'. cornula especially in having the inner margin distinctly 

 convex (fig. 43) and the inner distal lobe not triangular but obtuse and somewhat broadly rounded,
