Rostrum er (so Fig. 6) mindro tydeligt begraendset 
* ra Rasalstykkenie, saa at jeg fprst tog fail af (lets Form. 
synes imidlertid at vsere vel udviklet og kileformigt 
cllcr pyramidalt som hos Sc. Str0nnii, med Basalranden 
temmelig bred, og jevnt afsmalnende mod Spidsen. 
Stilken er forholdsvis kort, neppe mere end halvt saa 
^ aa 8 som Oapitulum og noget indknebet paa Midten, uden 
^°g at vise nogen maerkbar Boiniug. Den er som hos Sc. 
tcemii daekket af store regelmgessigt taglagte Kalkskjael, 
1:1 alene ved den noget udbredte Basis bliver meget smaa 
°g rudimentsere. 
Den ydre Beklsedningsmembran er overalt, saavel paa 
Oapitulum som Stilken, ru af fine Smaapigge, der ligesom 
fint Dun overdrager hole Legemet. 
Paa et af de undersogte Exemplarer fandtes fsestede 
® Indsiden af Skjoldene mer deres Aabningsrand 2 af de 
e it'tidommelige supplementaere Hanner, hvoraf den ene er 
afbildet Fig. 7 staerkt forstOrrret. Legemet er blodt, uden 
8 P° r af Valvler eller Kalkplader, hvorimod den tynde con- 
Daetil© Had er overalt ru af yderst fine Smaapigge. Af 
"nn er det temmelig regelmsessigt ovalt og viser i den 
® ne Rude en af 4 lmbeformige Fortykkelser begrsendset 
ahning, hvorigjennem et Bundt af stive Burster (de rudi- 
nientsere Randor) rager frem. Paa den ene Side af Lege- 
mot °6 i temmelig b.etydelig Afstand fra den aborale Elide i 
* (ies de 2 Hefteantenuer med sine Borster og Hefteskiver. 
e gemet er fyldt med et fint kornet Indhold og i den ydre 
, Uc ^ se es tydelige fra Hefteorganerne radierende fine Muskel- 
fibre. 
Farven er som bos de 2 foregaaende Arter ensformig 
hvid. 
Esengden af det storste erholdte Exemplar er 35 mm , 
nairvaerende Form horer saaledes til de storste bekjendte 
lter a f Slsegten. 
Forokomst. Yi har taget denne smukke Art paa 3 
jellige Stationer, alle tilhorende den kolde Areas Dyb. 
Af dis se ligger de 2 (Stat. 18 og 35) i Havet mellem Norge 
^ Emroerne, den 3die (Stat. 312) NY af Beeren Eiland; 
ybclen fra 412 til 1081 Favne. Exemplarerne fandtes 
■istheftede dels til Spongier, dels til Smaastene fra Hav- 
bunden. 
Plie rostrum (see fig. 6) is less distinctly marked off 
from the basal segments, a character that at first led me 
to misapprehend its form. Meanwhile, it would appear to 
be well developed, and cuneiform or' pyramidal, as in Sc. 
Strmrn, with the basal margin rather broad and gradually 
tapering toward the extremity. 
The peduncle is comparatively short, scarcely more 
than half as long as the oapitulum, and a trifle constricted 
in the middle, without however exhibiting any appreciable 
flexure. As in So. Stmmii, it is covered with large cal- 
careous imbricate scales, and which, at the somewhat ex- 
panded base only, become exceedingly small and rudimen- 
tary. 
The outer investing membrane is everywhere, both 
on the capitulum and the peduncle, rough to the feel from 
minute spikelets, which, with the aspect of a delicate pubes- 
cence, extend over the whole body. 
On one of the specimens examined, were found, at- 
tached to the inner side of the scuta, near their occluding 
margin, 2 of the peculiar supplementary males, one of which 
has been represented in fig. 7, highly magnified. The body 
is soft, without a trace of valves or calcareous plates, whereas 
the tenuous, contractile skin occurs everywhere roughened, 
from exceedingly minute spikelets. In form, it is approx- 
imately oval, and exhibits at one extremity an orifice, de- 
fined by 4 labiate inspissations, through which a fascicle 
of stiff bristles (the rudimentary tendrils) are seen to pro- 
ject. On one side of the body, and placed at a consider- 
able distance from the aboral end, occur the 2 antennae 
of attachment, with their bristles and discs. The body 
contains a finely granular substance; and m the outer in- 
tegument may be distinctly seen delicate muscular fibres, 
radiating from the organs of attachment. 
Colour, as in the 2 preceding species, a uniform 
white. 
Length of the largest specimen obtained 35—, and 
hence the present form ranks among the largest known 
species of the genus. 
Occurrence. — This beautiful species was taken on 
the Norwegian Expedition at 3 different Stations, all be- 
longing to the cold area. Two (Stats. 18, 35) lay in the 
tract of ocean between Norway and the Faeroes, the 3rd 
(Stat 312) north-west of Beeren Eiland; depth ranging 
from 412 to 1081 fathoms. The specimens were found in 
part attached to sponges, in part to rubble from the sea-bed.
