the end anteriorly with a slender biarticulate claw and 3 small bristles; terminal 

 joint carrying on the end 5 curved setae and a slender claw of same appearance 

 as that on the penultimate joint. Posterior maxillipeds with the propodal 

 joint considerably dilated and oval in form, carrying somewhat beyond the 

 middle a short spine and in front of it a slender seta; dactylar joint exserted 

 in the form of an almost straight claw with a slender spinule at the base. 

 Natatory legs with the rami in the 3 anterior pairs nearly equal-sized; inner 

 ramus of 4th pair, however, much reduced in size, forming a single oval joint 

 with 2 somewhat unequal spines on the tip. Last pair of legs with the free 

 joint rather small and oblong in form; apical setae not much produced and 

 subequal in size. 



Colour not yet ascertained. 



Length of the specimen examined 0.45 mm. 



Male unknown. 



Remarks. The above-described form may be easily distinguished from 

 any of the other Lichomolgidae by its small size, the unusually short anterior 

 antennae and the structure of the tail. 



Occurrence. Only a single specimen of this form, an apparently full- 

 grown female, has hitherto come under my notice. It was picked up from a 

 sample taken several years ago at Skutesnaes, SW coast of Norway, from a 

 depth of about 20 fathoms.

Specific Characters. Female. Body moderately slender, with the an- 

 terior division oval fusiform in outline, greatest width about half the length 

 and occurring in the middle, dorsal face evenly vaulted throughout. Last 

 trunkal segment extremely small. Tail not attaining half the length of the 

 anterior division; genital segment evenly dilated in the middle and slightly 

 longer than the remaining part of the tail; anal segment larger than either of 

 the 2 preceding segments. Caudal rami comparatively short, scarcely attaining 

 the length of the anal segment; seta of outer edge attached about in the 

 middle; apical setae not much produced, that of the inner corner very small, 

 shorter than that of the outer. Structure of the several appendages very similar
