Remarks. Jn tin- -lender form of the .-interior antenna 1 and in the struc- 

 ture of tin 1 1st and la-t pairs of legs, this species -'''-ins to agree i-\.-ictly with 

 the form dcsrrihed ly Th. Scott under the abo\e name. The si/.e of the Nor- 

 \\e-ian specimens is houever inucli inferior to that recorded !>y Th. Scott (<U'>7 



nun.), and for this reason the identih of these 2 forms may perhaps appear some- 



\\liat douhtful. 



Occurrence. 1 ha\e met with this small species not (infrequently in 

 places both off the south and west coasts of Norway in moderate depths

>'/r///V- Clttn-iirfrr*. Fi'HKtli'. Body rather slender, sublinear in form, with 

 the cephalic segment less deep than in the preceding species. Last caudal seg- 

 ment shorter than the preceding one. Caudal rami about as long as they are 

 broad and transversely truncated at the tip, apical setae of moderate length. 

 Anterior antenna- shorter than the cephalic segment, and having the 2 basal joints 

 rather dilated, terminal part not attaining half the length of the proximal one. 

 Mandibular palp with a single thiekish seta inside the basal joint. 1st pair of 

 legs with the outer ramus about half the length of the inner, terminal joint of 

 the latter very -lender, linear in form, being about 3 times as lon.^ as the 2nd. 

 both together nearly as long as the 1st. Last pair of legs resembling those in 

 .1. tenuicomis, but with the distal joint comparatively smaller.
