his genus Andaniu, and Lis generic diagnosis agrees pretty well with this 

 species, but not with the other form he comjDrises in the same genus. When 

 alive, this form is at once recognized by the very conspicuous milk-white eyes, 

 and the dark greyish colour of the body. 



Occurrence. — The species is a true deep water form, only occurring 

 in greater depths, from 200 to 400 fathoms. I have met with it in several 

 places off the west coast of Norway, and northwards to the Lofoten Isles, 

 as also in the Trondhjemsfjord. Boeck records it also from Christianiafjord. 



Disrihufion. — Outside the great fishing banks of the Norwegian 

 coast (Norw. North Atlantic Exped.).

Form of body about as in the preceding genus. Cephalon rather 

 short, with the lateral corners but little projecting. Coxal plates, compara- 

 tively, somewhat deeper than in Andania ; 4th pair rather l)road, fully 

 encompassing the succeeding pair interiorly. Eyes distinct, though rather 

 small. Antennae subequal in length, flagellum of the superior ones only composed 

 of 4 articulations. Epistome rounded in front. Anterior lip distinctly bilobed. 

 Mandibles nearly of same shape as in Andania, but with the cutting edge 

 minutely dentate. First pair of maxillse comparatively less strong, masticatory 

 lobe rather narrow, palp very small, uniarticulate, not reaching to the 

 end of the former. Second pair of maxillae nearly of same structure as 

 in Andania. Maxillipeds with the l)asal lobe well-developed, and transversely 

 truncated at the tip, masticatory lobe rather large, obliquely oval, and 

 finely spinulose inside, palp very slender. Gnathopoda nearly exactly alike, 

 both as to size and structure, propodos in both rather narrow, tapering 

 distal ly, dactylus short and smooth. Penultimate pair of pereiopoda with the 

 basal joint narrow, linear. Last pair of pereiopoda much smaller than the 

 preceding pairs, basal joint laminarly expanded, meral joint very large and 

 produced at the infero-posterior corner. Uropoda and telson nearly as in 

 the preceding genus. 



RemarJcs. — I have found it necessary to establish this new genus 

 in order to include the form described by Boeck as Andania. nordJandica. 

 The closer anatomical examination of this form has indeed shown it to differ 

 from the t3qie of the genus Andania in some characteristics apparently of 

 generic value. Thus the mandibles, tliough being otherwise rather similar,
