During the Swedisli Arctic Expedition of 1<S98, this spe- 

 cies whicli, at the first glance, re.'^enil)les veiy mueh the iiearly 

 allied Antaretic Edotett tnhcrciihitd Guérin-Méneville. was 

 collected only at one locality, viz.

In the most important points I have found my specimens 

 agree very well with Kröyer's description and figures. The 

 fiagellum of the antenn* in the male consists of 10 — 11 joints, 

 that in the female of 6 — 7 joints. 



Length of the greatest male 21,5 ram.

The colour is a uniform dark olive-green, sometimes, on the 

 epimeres, with a trace of purplish spöts, like those in Sf/n- 

 idothca hicusinda. 



The species is first described b}' Kröyer on specimens 

 from "W^est Grreenland, where it has been found as far north 

 as GodhaYn (Hansen). Låter on, it is collected almost in 

 every part of the Arctic Ocean, although it does not seem 

 to occur very abundantly. Harger mentions it from the 

 Pacific coast of Xorth America as far south as British Co- 

 lumbia, and from the East coast southward to St. George's 

 Bank; further eastward, it is collected off Spitzbergeu, in 

 the Murman and in Barents Seas, off Nova Serabla, in the 

 Kära and Siberian Seas, and in the North American Archi- 

 pelago. Thus, it has a circumpolar distribution. It lives in 

 shallow water, mainly on sand or clay. and the greatest depth 

 from which it has been dredged is, I think, 90 m.
