pair provided with 2 strong spinulose setae; apical spine and seta in all pairs 

 very long and slender ; inner ramus scarcely half as long as the outer, with the 

 1st joint very small and simple, middle joint the largest and produced at the end 

 inside to an acute corner, terminal joint carrying on the tip a moderately long 

 spine and inside 2 unequal setae, the distal one very long and slender. Last pair 

 of legs with the distal joint well-developed, oval in form, and edged with 6 setae 

 of rather unequal length, the innermost but one very long and slender; inner 

 expansion of proximal joint comparatively short, not extending to the middle of 

 the distal joint, and carrying at the obtusely rounded extremity 2 unequal setae 

 and inside them 2 short spines bifid at the tip. 



Colour not yet ascertained. 



Length of adult female 0.48 mm. 



Remarks. The above-described species is unquestionably referable to the 

 genus ' Phyllocamptus, as defined by Th. Scott, and comes very near P. fairliensis 

 Scott. It is however of much smaller size and differs moreover in the perfectly 

 smooth caudal segments, as also slightly in the structure of the legs. 



Occurrence. Only a solitary female specimen of this form has hitherto 

 come under my notice. Is was found in a sample taken last summer at Korshavn 

 from a depth of about 20 fathoms. 



Gen. Paramesoehra, Scott, 1892. 



Generic Characters. Body more or less slender, with the anterior division 

 distinctly broader than the posterior and somewhat depressed. Integuments very 

 hard. Rostrum obsolete. Genital segment in female large, not subdivided. Caudal 

 rami more or less produced. Anterior antennae short and stout. Posterior antennas 

 with the proximal joint distinctly subdivided, outer ramus well developed, though 

 uniarticulate. Mandibles very strong, with the palp well developed, biramous. 

 Maxillae comparatively small, with the epipodal lobe imperfectly developed. An- 

 terior maxillipeds with 4 subequal setiferous lobes inside, the outermost issuing 

 from the distal joint, apical part well defined. Posterior maxillipeds with the 

 dactylus composed of a small basal joint carrying 2 or 3 claw-like spines. Legs 

 comparatively small and of simple structure; 1st pair with both rami biarticulate, 

 the inner one distinctly prehensile; the 3 succeeding pairs with the basal part 

 broad and flattened, outer ramus 3-articulate, inner biarticulate; natatory setae 

 imperfectly developed. Last pair of legs with the distal joints very small, proximal 

 joints confluent inside to a large median plate.
