Lfengden gaar op til 15 mm . 
The telson (ibid.) is likewise very similar, but has 
the incision not quite so deep, though considerably exceed- 
ing half the length of the appendage. 
Colour in the recently taken specimens whitish, with 
a faint tinge of red. 
Length reaching 15’""'. 
Forekomst og Udbredning. Enkelte Exemplarer af 
^au \ amende Art erholdtes paa 2 forskjellige Stationer (St. 
b3 og 213), begge beliggende i Havet omtrent midt imel- 
'* an Mayen og Finmarken, Dybden fra 1710 til 1760 
<l 'ue. Den synes saaledes at vaere en for den kolde Areas

Occurrence and Distribution. — A few examples of 
the present species were obtained at 2 different Stations 
(Stats. 183 and 213), both about midway in the tract of 
ocean stretching between Jan Mayen and Finmarken; depth 
from 1710 to 1760 fathoms. It would, therefore, appear to 
be a form peculiar to the greater depths of the cold area.

Specific Character. — Body exceedingly tumid, with 
breadth almost equal to height. Lateral corners of head 
pointed. The 4 anterior pairs of epimera rather large; 
5tli pair about equal in height and breadth. Lateral 
plates of 3rd abdominal segment drawn out posteriorly 
as a sharp, somewhat upward-curving projection; 4th seg- 
ment slightly impressed in the middle. Eyes distinct, oval, 
broader below, with a red-coloured pigment. First pair of 
antennas with peduncle greatly swollen; flagellum short, 
with 1st articulation very large; secondary flagellum rather 
well developed, four-jointed. First pair of legs thickset, 
distinctly subcheliform, with the hand scarcely at all longer 
than the preceding articulation. The 3 posterior pairs of 
legs with basal joint large, lameffifonn, and of a regular 
oral shape. Caudal stylets robust, with naked, lanceolate 
branches. Telson short and broad, obtuse at extremity, 
with a short and narrow incision, that does not reach to the 
middle. Colour yellowish-red. Length 13’“. 
Locality. — Stat. 323. 
Remarks. — Of the known forms belonging to this 
enus , the present species approximates closest 0. Edwardsii 
Kroyer. from which however it may at once he distinguished 
by the remarkably clumsy and inflated form of body, a char- 
ter that gives the animal greater resemblance to 0. plautus 
Krover. which, in other respects, however, differs very 
decidedly.
