In the collections of the expedition of 1S9<S this species 

 is represented by five specimens which are all males. They 

 are from 



stat. 5. lat. 75' 49' N., loug. 24 25' E. between Beeren Islaud aud 

 Hope Islaud, depth 80 in., bottom terap. — 1,42' C, rocks,

Janira tricornis seems to liave a very restricted distribu- 

 tion, since it bas been found only in two parts of tbe Arctic 

 Ocean, viz., on the AVest coast of Greenland so far nortb as 

 Egedesminde (Kröyer, Hansen), and at Spitzbergen, wbere 

 the Norwegian ]^ortli Atlantic Expedition dredged it from a 

 station a little south of South Cape. By our expedition its 

 range extends farther east. Stebbing ^ also enumerates it 

 among crustaceans collected by Bruce 1898 in tbe sea east 

 of Spitzbergen. Everywbere it seems to occur very seldom. 

 The vertical distribution is from 5 to 70 fathoms, and it bas 

 hitherto been found only on stones or clay. 



Length of the greatest specimen (stat. 5) 8 mm., breadtb 

 3, .5 mm.
