lappet densely hairy and exserted to a slender setiform lash; palp provided at 

 the end with 3 setae, the innermost very small. Anterior maxillipeds with the 

 terminal process only slightly curved and having 3 of the denticles stronger 

 than the others. Posterior maxillipeds of moderate size, propodal joint scar- 

 cely as long as the basal one and provided inside, about in the middle, with 

 a short seta; dactylar joint conical in form and having outside a slender spine. 

 Inner ramus of the 3 anterior pairs of natatory legs somewhat longer than the 

 outer; that of 4th pair however rather shorter, with the terminal joint narrow 

 sublinear in form and only provided with 2 unequal spines, both issuing from 

 the end. Last pair of legs with the free joint subfusiform in shape, inner 

 apical seta short, spiniform, outer one 3 times as long. 



Colour not yet ascertained. 



Length of adult female 1.75 mm. 



Male unknown. 



Remarks. This new species is readily recognised by the broadly 

 expanded anterior division of the body, the comparatively short caudal rami, 

 and the very powerful structure of the posterior antennae. In size it is, next 

 to H. maxima (Thompson), the largest of the northern species. 



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

 come under my notice. It was taken, several years ago, in the inner part of 

 the Stavanger Fjord, at Hjelmeland, from a depth of about 50 fathoms, among 

 dredged material.

Specific Characters, Female. Body far less robust than in the pre- 

 ceding species, with the anterior division regularly oval in outline, greatest 

 width not nearly attaining half the length of the body and occurring in the 

 middle. Cephalic segment rather large and somewhat applanated, exhibiting 

 behind a well-marked transverse suture, front narrowly rounded. Epimeral 

 plates of the 3 succeeding segments obtusely rounded. Last trunkal segment 

 very small. Tail not fully attaining half the length of the anterior division 

 and attenuated behind; genital segment obpyriform in shape and scarcely longer 

 than the 3 succeeding segments combined. Caudal rami rather narrow, sub- 

 linear in form, and scarcely at all divergent, exceeding in length the 2 preced-
