by the rather deviating form of the 4th pair of coxal plates, as also by 

 the more strongly produced meral joint of the 3 last pairs of pereiopoda. 



Occurrence. — A few specimens of this form I have collected in 2 

 places off the Nordland coast, viz., Kvalo and Selsovig, at a depth of 30 

 to 40 fathoms. Some other specimens were found in the Amphipodous 

 collection of Boeck, but without any name or statement of locality,

20. Metopa propinqva. n. sp 



(PI. 03, flg. 1). 



Form of body nearly as in 31. sinuafa. Cephalon about twice as 

 long as the 1st segment of mesosome, lateral corners nearly rectangular. 

 Coxal plates rather large; 2nd pai'' obliquely rounded at the tip; 3rd pair 

 fully twice as deep as the corresponding segment, and scarcely widening 

 distally; 4th pair of a very similar form to those in M sinuata, the distal edge 

 being distinctly sinuated in the middle, anterior corner somewhat more 

 broadly rounded. Last pair of epimeral plates of metasome considerably 

 produced at the lateral corners. Eyes rather large, rounded, ])igment dark 

 red. Antennse much more elongated and slender than in 31. sinuata, the 

 superior ones nearly attaining half the length of the body, 1st joint of the 

 peduncle about the length of the other 2 combined, flagellum more than 

 half as long again as the peduncle, and very slender. Inferior antennae 

 shorter than the superior, the 2 outer joints of the peduncle nearly of equal 

 length, flagellum fully as long as those joints combined. Anterior gnathopoda 

 comparatively small, propodos shorter than the carpiis, and umch narrower, 

 inferior edge without any denticles. Posterior gnathopoda rather powerful, 

 propodos much longer than the 3 preceding joints combined, and rather 

 expanded, palm scarcely as long as the hind margin, from which it is defined 

 by an acutely produced projection, its edge distinctly serrated, dactylus 

 rather strong. First pair of pereiopoda comparatively slender, the others 

 powerfully developed; last pair with the basal joint irregularly rounded, 

 the posterior edge bulging out considerably in the middle, meral joint rather 

 lai'ge. and produced at the end posteriorly, to a curved lobe reaching beyond the 

 carpal joint. Last pair of uropoda with the basal joint shorter than the 

 other 2 combined, and armed with 3 unusually strong denticles blunt at the 

 tip. Telson oblong linguiform, more than twice as long as it is broad, and 

 armed with 3 pairs of strong dorsal denticles, tip narrowly rounded. Body
