Forekomst. Adskillige Exemplarer af denne Art blev 
U| uler Expeditionen indsamlede, fsestede til Tubularierpr og 
Pongier fra 2 forskjellige Stationer. Den ene af disse 
(Stat. 18) ligger i Havet mellem Norge og Fmrperne, den 
anden (Stat. 343) SY af Spitsbergen; Dybden fra 412 til 
^' J> Pavne. Begge Stationer ti l borer den kolde Area. 
^ lten er nordlig udbredt til Havet om Franz Josephs 
a nd, hvor den forst blev fundet under den 0ster.-U ngarske 
or dpolexpedition. 
On the other band, the rostrum (see tig. 4) lias quite 
a different appearance. It is exceedingly narrow, linear, 
and not broader at the base than at the point. 
The peduncle is well-nigh equal in length to the 
capitulum, almost cylindric, and quite straight. The cal- 
careous scales, too, are appreciably different, being more 
scattered, and not imbricate as in Sc. Stromii, but sepa- 
rated one from the other by a relatively thin-skinned inter- 
space. They occur in oblique transversal series, and are 
largest on the middle part of the peduncle. 
The outer investing membrane, alike on the capitulum 
and the peduncle, is, as in Sc. Stromii , quite smooth, 
without a trace of spikes. 
Colour, in all the specimens examined, a uniform 
snowy white. 
Length of the largest individuals reaching 13””. 
Occurrence. — Several specimens of this form were 
collected on the Expedition, at different Stations, attached 
to sponges and tubularise. One of these Stations (Stat. 18) 
was located in the tract of ocean between Norway and the 
Faroes, the other (Stat. 343) lay south-west of Spitz- 
bergen;* depth ranging from 412 to 743 fathoms. Both 
Stations lay within the cold area. The species , extends 
northward to the Sea surrounding Franz Joseph’s Land, 
where it was first observed on the Austrio-Hungarian North 
Pole Expedition.

Specific Character. — Capitulum rather closely ap- 
proximating an oval or elliptic form, more than twice as 
long as broad, not expanded towards the end, with apex 
relatively short and bent a trifle upwards, as also extend- 
ing well-nigh in the axis of the shell. Valves in close 
contact, with a clearly prominent sculpture of radiating 
ribs Keel slender, evenly arcuate, without umbo. lei gal 
segments very large, with occluding margin shorter than 
basal Apical angle of shields acutely produced. Upper 
Lateral segments broader than shields, with 5 rather prom- 
inent radiating keels and a strong umbo-shaped projection. 
Dorsal basal segments comparatively broad, irregular- 
ouadratic, not projecting at base; median basal segments 
small triangular, with basal part tapering wedge-shaped; 
ventral basal segments somewhat smaller than dorsal, but 
larger than median. Rostrum not very distinctly defined 
Rom basal segments, pyramidal in form, broadest at base 
Peduncle short, slightly instricted at base, straight, overlaid
