tionen taget dome smukke Form enkeltvis paa 5 forskjel- 
Stationer. Af disse ligger de 2 (Stat. 31 og 87) i 
H.imt udenfor BrOinsdalen, den 3die (Stat. 48) 0st af Island, 
den 4 de (Stat. 200) NY. af Finmarken og den 6te (Stat.

Dens for Tiden bekjendte Udbredningsfelt er herefter 
teinnielig betydeligt og strsekker sig fra den 63de til den 
7<ide Bredegrad og fra omtrent 31° 0. L. til 10° Y. L. 
A' ten er utvivlsomt at betragte som en segte arktisk Form.

Occurrence and Distribution. - This beautiful form 
was taken on the Expedition — isolated specimens — at 
5 different Stations. Two of these (Stats. 31 and 87) were 
located in the open sea, off the coast of Romsdalen; the 
3rd (Stat. 48) lay east of Iceland, the 4th (Stat. 200) 
north-west of Finmark, and the 5th (Stat. 338) south oi 
Spitzbergen. All of the Stations were in the cold area; 
depth from 146 to 620 fathoms. The species occurs, too, 
off the shores of Norway, viz. in the Varangerfjord, where 
I have not infrequently taken it at a depth ol about 100 
fathoms. 
Hence, its range of distribution, as at present known, 
is rather considerable, extending from the 63rd to the 76th 
parallel of latitude, and from long. 31° E. to long. 10° \Y. 
The species must unquestionably be ranked as a true Arctic 
form.

Specific Character. — Body exceedingly slim, with 
small epimera, 1st pair largest, rounded at extremity. 
Lateral corners of head obtusely rounded. Lateral plates 
of 3rd abdominal segment almost rectangular. No eyes. 
First pair of antenna; somewhat shorter than body; with 
the 2 first joints of peduncle about equal in length; flagellum 
shorter than peduncle, secondary flagellum four -jointed. 
Second pair of antennae one-third shorter than 1st. First 
pair of legs feeble in structure, with hand scarcely at all 
larger than preceding joint; second pair exceedingly robust, 
with broad, well-nigh quadrate hand. Remaining legs very 
slender, the 3 posterior pairs longer than the 2 preceding 
ones, with basal joint narrow, linear. Terminal pair of 
caudal stylets about same size as preceding pair, with both 
branches lanceolate and well-nigh equal in length. Telson 
short, bilobular. Colour whitish, translucent. Length
