by the general form of the body and more particularly by the structure of the 

 last pair of legs in the female. 



Occurrence. Off the west coast of Norway this form is by no means of 

 rare occurrence in the littoral region. I have taken it rather plentifully at 

 Aalesund and Christiansund, as also in the outer part of the Trondhjem Fjord, 

 and it is also recorded by Th. Scott from the Finmark coast. 



Distribution British Isles (Brady), coast of France (Canu), Mediterranean 

 (Glaus), the Red Sea (A. Scott), Bear Island (T. Scott), Franz Josef Land (same 

 author).

Specific Characters. Female. Body somewhat more slender than in D. 

 thisboides, and less regularly tapered behind. Cephalic segment less broad, with 

 the rostrum more prominent. Urosome with the segments more sharply marked 

 off from each other, each with a very conspicuous transverse row of spinules near 

 the hind edge ventrally and laterally. Anterior antennse comparatively more 

 slender and distinctly 9-articulate, distal part exceeding the length of the 3 pre- 

 ceding joints combined. Posterior antenna? with the outer ramus comparatively 

 smaller. 1st pair of legs with the outer ramus considerably exceeding half the 

 length of the inner, apical claws of moderate length and scarcely spinulose, apical 

 claws of inner ramus very unequal, the inner one more than twice as long as the 

 outer. Last pair of legs rather different in shape from those in D. tliisboides, 

 distal joint comparatively larger, oval cordate in form and edged with 7 not much 

 elongated setffi, 2 of which issue from the inner edge; inner expansion of proximal 

 joint much smaller than in D. thishoides, extending only slightly beyond the middle 

 of the distal joint; none of the marginal setse remarkably elongated. 



Male having the distal joint of the inner ramus of 2nd pair of legs 

 scarcely curved at the tip, apical spines subequal in length, spine of outer edge 

 more slender than in D. thisboides and attached rather in front of the middle. 

 Last pair of legs resembling in shape those of female, but of smaller size and 

 with only 3 marginal spines on the proximal joint. 



Colour pale yellow. 



Length of adult female 0.85 mm.
