and distinctly 12-articulate anterior antennae, and the remarkably short caudal 

 rami, which latter character has given rise to the specific name here proposed. 

 Occurrence. I have met with this form in several distant places on the 

 Norwegian coast, for instance at Ris0r on the southern coast, at Skutesnses on 

 the south-western coast, and at Bejan outside the Trondhjem Fjord. A single 

 well-marked ovigerous specimen was found, moreover, in a sample taken by Mr. 

 Nordgaard in the Porsanger Fjord, Finmark. The specimens observed by me 

 were taken in depths ranging from 10 to 30 fathoms, muddy bottom.

Specific Characters. Female. Body very slender, with the anterior division 

 narrow oblong in form, greatest width not attaining half the length and occurring 

 in its anterior part, front evenly rounded. Tail almost as long as the anterior 

 division and having the genital segment unusually large and tumid, clothed on 

 each side with small spikes; anal segment fully as long as the preceding one. 

 Caudal rami long and slender, equalling in length the last 2 segments combined; 

 outer edge with 2 successive bristles, the smaller one occurring at a short distance 

 form the base, the other attached nearer to the end and somewhat dorsally ; 

 apical setae of moderate length, that of the outer corner shorter than that of the 

 inner. Anterior antennae moderately slender, though not attaining the length of 

 the cephalic segment, and composed of 18 joints, the 4th and 5th joints exhibiting, 

 however, a more or less distinct sub-division, so that the number of joints may 

 be increased to 20 21. Posterior antennae with the terminal joint scarcely longer 

 than the antipenultimate one, Mandibular palp comparatively more slender than 

 in the other species, with the outer ramus shorter. Posterior maxillipeds with 

 the terminal part composed of 5 well-defined joints. 1st pair of legs, like the 3 

 succeeding ones, provided with 2 setae inside the middle joint of the inner ramus, 

 these setae being in 4th pair very coarse, almost spiniform. Last pair of legs 

 distinctly 3-articulate. 1st joint with a coarse ciliated seta inside, middle joint 

 rather dilated and carrying outside the usual slender bristle; terminal joint nar- 

 row oblong in form, exceeding in length the other 2 combined, and provided 

 outside with 2 setae, at the tip with another very slender seta and a stout spine. 

 Ovisacs of moderate size and somewhat divergent.
