propodos, and produced at the end inferiorly to a lammellar setous lobe, 

 somewhat larger on the posterior pair, though not quite extending to the 

 palm, meral joint in both pairs simple, without any dentiform projection. 

 Pereiopoda rather slender, and densely edged with fascicles of small bristles; 

 basal joint of the 3 posterior pairs very large, especially that of the last pair. 

 Uropoda with the rami densely spinulose, last pair reaching about as far as the 

 1st pair, basal part scarcely longer than the rami. Telson of moderate 

 size, not quite extending to the end of the basal part of the last pair of 

 uropoda, conical]y tapering distally. Body of whitish colour, banded with 

 light red. Length of adult female b l /z mm. 



Remarks. The above described form, which was referred by Boeck 

 to the genus Amphilochus, may properly be regarded as the type of the present 

 new genus. It is easily recognized by the 2 recurved dorsal processes of 

 the metasome, from which characteristic, indeed, the specific name was derived. 



Occurrence. Though nowhere in any abundance, I have met with 

 this form in several places, both off the south and west coasts of Norwa.y, 

 as also in the Trondhjemsfjord. It extends northwards to the Lofoten Isles, 

 where I found it many years ago at the fishing place Skraaven. Boeck 

 records it from Christianiafjord, Haugesund, Hardangerfjorcl and Christian- 

 sund. It occurs, as a rule, only in rather deep water, from 50 to 100 

 fathoms. 



Distribution. Greenland (Hansen); coast of France (Chevreux).

Body quite smooth, and very like in its outer appearance that of the 

 species of Amphflochus, though being perhaps somewhat more slender. 

 Cephalon not fully as long as the first 2 segments of mesosome combined, 

 rostrum strongly curved, and reaching beyond the middle of the basal joint 

 of the superior antennae, lateral corners but little projecting, and nearly 

 rectangular. First pair of coxal plates very small, obliquely quadrangular 

 in form ; 2nd pair slightly expanded in their outer part, distal edge rounded 

 nnd coarsely dentatecl, 4th pair considerably deeper than the corresponding 

 segment, distal edge evenly curved. Last pair of epimeral plates of meta- 

 some nearly rectangular. Eyes rather large, rounded oval in form, with 

 well- developed visual elements. Antennas comparatively short, and subequal 

 in length, the superior ones with the first 2 joints of the peduncle nearly
