as in this species. Last joint (with the claw) of the second 

 pair of maxillipeds is of more than half the length of the 

 preceding joint. In A. ahhreviata it is much shorter. Perei- 

 opods and pleopods of the usual structure. 



As mentioned above, a single specimen of Amhlijops Cro- 

 zetii was taken in the Southern Ocean off Crozet Islands in 

 lat. 46" 16' S., long. W 27' E. at a depth of 1600 fathoms. 

 The find of it in the Arctic Ocean was. therefore, very sur- 

 prising and seems, in my opinion, to corroborate the view of 

 Chun that a communication of animals still exists in the 

 deeper or abyssal strata of the oceans between the Arctic 

 and Antarctic seas. However, further researches in the far 

 Southern Ocean afford the only nieans of fully settling the 

 interesting problem of »bipolarity».

Fig. 4. 



Carapace submembranaceous, covering whole pereion ex- 

 cept the hindmost segment. Sixth segment of pleon as long 

 as the three preceding ones. The anterior, or cephalic, part 

 of the carapace is marked off by a distinct sulcus and 

 arched above. The frontal margin ends in an angle, which, 

 seen en profih', seems to form a short, somewhat upturned 

 rostrum. The antero-lateral corners evenly rounded. 



The eye-scales, or ocular plates, as compared with those 

 in the other species of the genus, rather small, not conti- 

 guous, with a free space between them. They are of an almost 

 quadrate form, with a sharp line running along the lateral 

 side. The upper side with a short styliform process visible 

 from above and from the medial side. The anterior-inferior 

 margin is rounded ofF. 



The peduncular joints of the antennula3 very large, short 

 and thick, especially the last one, which is as long as the 

 two proximal ones, but broader. An oblique, broad band of 

 dark-brown pigment-spots is on the upper side of the third 

 joint, which gives it a somewhat stränge appearance. As the 

 distal part was broken off, it was impossible to make out 

 the exact form of the antennal scale. The non-setous part of
