of thrin detected e\ en the slightest trace of the >] uniform lappet on the 2nd joint 

 of thi' anterior antenna- so characteristic of .1. il>-)ili,-n/iifii.-.-. I think that it must 

 be kept apart from that species. 



Occurrence. Some specimens of this form, all of the female sex. \vcre 

 loiiiid ill a sample taken last summer at Korshavn from moderate depth. It also 

 occurred occasionally in another locality, vi/.. at Aunefest. uppermost part of the 



Fjord.

(Siip|,l. I 1 !. 19. li.-r. 2). 



N//CC///C ('htirin-ti-r*. - 1^'nuih'. Body rather slender and only slightly atten- 

 uated behind, with very thin and pelluid integuments. Rostrum prominent, 

 i-onically produced. I'rosome not nearly attaining the length of the anterior 

 division, last segment scarcely shorter than the preceding one. Caudal rami 

 -ln.it. broader than they are long; apical setae normal. Eye replaced by a diffuse 

 branching pigment of a light yellow colour. Anterior antenna- moderately slender. 

 > articulate-, the first 2 joints much the largest and sube((iial in sixe, 4th joint a 

 little longer than 3rd. terminal part scarcely exceeding in length those joints 

 combined. Posterior antennae with the middle joint of the outer ramus well 

 defined and setiferous. 1st pair of legs with the outer ramus considerably shorter 

 than the 1st joint of the inner, middle joint without any seta inside, last joint 

 !' about same sixe and armed with 3 spines and 2 geniculate seta-; inner ramus 

 with the 1st joint narrow linear in form carrying near the end inside a slender 

 i. la^t joint 3 times as long as the middle one and armed in the usual manner, 

 both joints combined scarcely more than half as long as the 1st. Natatory legs 

 with the rami very slender, but having the full number of seta?. Last pair of 

 leg> with the distal joint oval in form, tip slightly bilobular. marginal setae 

 comparatively shoit and i in number, the 2 apical ones vry thin, hair-like: 

 inner expansion of proximal joint narrow triangular and extending somewhat 

 beyond the middle of the distal joint, marginal seta- ~> in number. 



' olour whitish.

RemarJcs. This form may. in the fresh state, at once lie recognised by 

 its lik'lily pellucid body and the imperfectly developed visual organ. In the 

 structural details .-iKo Mime \\ell marked differences are round to exist, distinguish- 

 ing it from the other known species.
