 along the Nordland coast to Selsovig lying exactly within tlie polar circle. 

 Off the coast of Finmark I have, on the other hand, not met with it.

 Syii. (Edioeros affinis, Goes (part). 



Body ratlier stout, with the segments sharply defined. Cephalon not 

 attaining the length of the 3 anterior segments af mesosome combined, fron- 

 tal part strongly convex, rostrum rather large, deflexed, acute, reaching 

 beyond the basal joint of the superior antennae. First pair of coxal plates rather 

 expanded distally, 4th pair somewhat deeper than the corresponding segment, 

 and regularly quadrangular in form, with the distal edge evenly curved and 

 the infero-posteal corners but little produced. Eyes of moderate size, placed 

 within tlie strongly convex fore-part of the front, pigment bright red. Su- 

 perior antennae in female about the length of the cephalon and the 3 anterior 

 segments of mesosome combined, 1st joint of the peduncle equalling the length 

 of the other 2 taken together, 2nd joint produced at the end anteriorly to a 

 nodiform projection provided with stiff anteriorly curving bristles, flagellum 

 a little longer than the peduncle, and composed of about 8 articulations. 

 Inferior antennae scarcely longer than the superior, last joint of the peduncle 

 shorter than the penultimate one, ilagellum scarcely more than half as long 

 as the peduncle.. Anterior gnathopoda rather strong, propodos somewhat 

 curved, and oblong oval in form, with the palm about the length of the hind 

 margin, carpal lobe comparatively short, not extending to the palm of the 

 propodos. Posterior gnathopoda a little more slender than the anterior, though 

 scarcely longer, propodos about 3 times as long as it is broad, carpal process 

 not extending to the palm of the latter. The 2 anterior pairs of pereiopoda 

 nearly as in 31. pallidum; the 2 succeeding ones with the basal joint com- 

 paratively broader and the propodal joint longer. Last pair of pereiopoda 

 extremely elongated, propodal joint the longest, and provided on both edges 

 with slender setae, carpal joint exceeding the length of the 2 preceding joints 

 combined, terminal joint very narrow. Telson oval quadrangular, with 

 the terminal edge slightly insinuated. Colour yellowish, with shadows of a 

 diffuse orange pigment; ova in the marsupial pouch dark violet. Length 

 of adult female 7 mm.
