og bagtil endende med en fremstaaende triangulært
tilspidset Flig.
Forkropssegmenterne er meget korte og brede; de
til dem horende Epimerer særdeles smaa. De 4 forreste
Par af disse sidste er noget skraat fortilrettede og nedad
jevnt tilrundede; de 3 bagerste svagt 2-lappede.
De forreste Bagkropssegmenter er temmelig høie og
tiltager hurtigt i Størrelse, saa at 3die Segment næsten er
ligesaa stort som de 2 foregaaende tilsammen; dets
Sideplader ender bagtil med et omtrent retvinklet Hjørne. De
3 bagerste Segmenter er særdeles korte.
Øine synes ganske og aldeles at mangle.
lste Par Følere er temmelig forlængede og ulige samme
hos de øvrige bekjendte Arter. Skaftets 3 Led er
indbyrdes omtrent af ens Længde, uden Børster og noget
fortykkede paa Midten eller adskilte ved bemærkelige
Indsnø-ringer. Svøben er neppe mere end halvt saa lang som
Skaftet, sylforinig tilspidset og kun bestaaende af 4 Led.
Bisvøben er ganske rudimentær, 1-leddet.
2det Par Følere er rettede udad og bagtil langs
Siderne af Legemet og derfor vanskelige at undersøge uden
Dissection. De er betydelig kortere end lste Par og har
Skaftets 2 sidste Led i begge Kanter besatte med stive
Borster.
De 2 forreste Podpar er indbyrdes af ens Bygning,
men af noget ulige Størrelse. Næstsidste Led eller Carpus
er meget stort og bredt, hvorimod selve Haanden er
forholdsvis liden.
De 2 følgende Par er kraftigt udviklede og tæt
børste-besatte.
5te Par er af særdeles robust Bygning, med
Hofteleddet kort og bredt, de øvrige Led i Enden stærkt
udvidede og besatte med knippevis ordnede Torner; Endekloen
næsten lige.
De 2 bagre Par er af en lignende plump Bygning,
men er noget mere forlængede, med Hofteleddet større og
af oval Form; paa 6te Fodpar er dette Led i Kanterne
besat med lange og stive saugtakkede Børster.
De 2 bagre Par Halefødder er meget smaa og af ens
Bygning, uden tydelige Borster eller Torner.
Halevedhænget er forholdsvis lidet og dybt kløftet.
Farven var paa det friskt indfangede Exemplar
hvidagtig noget spillende i det gule.
Længden er kun 3""".
Forekomst. Et enkelt Exemplar af denne lille Art
erholdtes under Expeditionen^ 2det Togt i Havet XV. af
Finmarken (St. 200) fra et Dyb af 620 Favne. Stationen
tilhorer den kolde Area.
obliquely descending, and posteriorly, terminating in a
prominent triangular-pointed lappet.
The thoracic segments are very short and broad,
and their epimera exceedingly small. The 4 anterior pairs
of the latter occur directed somewhat obliquely forward,
below uniformly rounded; the 3 posterior faintly bilobular.
The anterior abdominal segments are rather high and
increase rapidly in size, the 3rd segment being almost as
large as the 2 preceding ones taken together; and its
lateral plates terminate posteriorly in a well-nigh
rectangular corner. The 3 posterior segments are exceedingly
short.
Eyes would appear to be absolutely wanting.
The 1st pair of antennæ ari’ rather elongate, and
unlike those in all other known species. The 3 joints of
the peduncle are about equal in length, without bristles,
and somewhat inspissated in the middle, or rather separated
by appreciable instrictions. The flagellum is scarcely half
as long as the peduncle, awlshaped-acute, and composed
of only 4 articulations. The secondary flagellum is quite
rudimentary, uni-articulate.
The 2nd pair of antennæ are directed outward and
backward along the sides of the body, and therefore
difficult to examine without dissection. They are considerably
shorter than the 1st pair, and have the 2 last joints of
the peduncle beset along both margins with stiff bristles.
The 2 anterior pairs of legs are uniform in structure,
but of somewhat unequal size. The penultimate joint, or
carpus, is very large and broad, whereas the hand itself is
comparatively small.
The 2 succeeding pairs are powerfully developed and
closely beset with bristles.
The 5th pair are exceedingly robust in structure, with
the basal joint short and broad, the remaining articulations
greatly dilated at the extremity and armed with fascicles
of spines; terminal claw almost straight.
The 2 posterior pairs are likewise clumsy in structure,
but a trifle more elongate, with the basal joint larger and
oval in form; on the 6th pair of legs, this articulation is
beset along the margins with long and stiff serrate bristles.
The 2 posterior pairs of caudal stylets are very small,
and uniform in structure, without distinct bristles or spines.
Thi’ telson is comparatively small, and deeply cleft.
Colour in the recently taken specimens whitish,
bordering on yellow.
Length not more than 4""".
Occurrence. — One individual only of this diminutive
species was obtained, on the second cruise of the
Expedition, in the sea north-west of Finmark (Ståt. 200), from a
depth of 620 fathoms. This Station was located in the cold
area.
