taken it very plentifully on a muddy bottom ; but as the appendages are extremely 

 brittle, it is rarely secured in a perfect condition. 



Distribution. — Several Stations of the Norwegian North Atlantic Expedition 

 (the present author), Skagerak (Meinert), Atlantic coast of North America (Harger).

 af Christianias og Christiansands Stifter. pag. 32. 



Sepcifie Characters. — Body oval, about twice as long as it is broad, and 

 slightly tapering both in front and behind. Cephalon with the frontal part con- 

 siderably produced, forming a narrow linguiform projection slightly bilobed at the 

 tip, outer edges of the lobes minutely denticulate. Anterior segments of mesosome 

 distinctly excavated above, lateral parts acutely produced in front; the 3 posterior 

 segments all well defined and of about equal length, antero-lateral corners pro- 

 duced. Caudal segment rather large, nearly twice as broad as it is long, and evenly 

 rounded at the tip, edges perfectly smooth. Superior antennae rather elongated, 

 with the flagellum composed of about 20 articulations. Inferior antennae about 

 3 times as long as the body, penultimate joint of the peduncle edged inside with 

 slender spines, flagellum about the length of the peduncle. Epignath of maxilli- 

 peds slightly angular outside. 1st pair of legs slender, with the propodal joint 

 scarcely more than half as long as the carpal one; the 3 succeeding pairs some- 

 what exceeding the length of the body, and very slender ; 2nd pair comparatively 

 stronger in male than in female, with the carpal joint slightly dilated and spinous 

 inside. Natatory legs of a similar structure to that in E. cornuta, though having 

 the dactylus comparatively smaller. Uropoda with the outer ramus much narrower, 

 but scarcely shorter than the inner. Colour of dorsal face light yellow, all the 

 segments bordered behind with light chestnut. Length of adult female 3 mm. 



Remar 7cs.— This species is nearly allied to E. cornuta, but of smaller size, 

 and is moreover easily distinguished by the less oblong body, the greatly produced 

 frontal part, and the different colouring of the dorsal face. 



Occurrence. — I have met with this species not rarely in several local- 

 ities of the Norwegian coast, from the Christiania Fjord to Vadso, in depths 

 ranging from 60 to 400 fathoms. Out of Norway it has not yet been recorded.
