blev den observeret paa Stat. 79 i Havet V af Nordlands- 
stem, samt paa 2 Stationer tilherende den kolde Area 
(Stat. 33 og 1.90), Dvbden indtil 870 Pavne. Arten er ikke

The peduncle is short and thick, greatly instricted at 
the base, and has, without exception, a sharp ventral bend. 
It is everywhere overlaid with large and regular calcareous 
scales, imbricate in arrangement, saving only those nearest 
the point of attachment, which are small and rudimentary. 
The outer translucent membrane, investing alike both 
oapitulum and peduncle, is quite smooth, without a trace 
of the delicate spikelets that occur here m Sc. vulgare. 
The animal itself would not appear t a exhibit any 
essential difference from Sc. vulgare. The 6 pairs of artic- 
ulated and bristle-bearing limbs designated cirrlu, or tendn s, 
are shown in the figures, partially extending from the orifice 
in the shell. . . 
On the inner side of the shields, in close proximity 
to their margin, was frequently observed, both in this and 
the succeeding species, one or two supplementary males 
of the same microscopic dimensions and rudimentary aspect 
as in Sc. striolatmn (see below). 
The colour, unlike that of Sc. vulgare , which invari- 
ably occurs as a more or less greyish-brown or brownish- 
yellow. is a pure snowy white, with the orange -tinted 
viscera (ovaries) shining through the integument. 
Length of the largest specimens reaching 13””". 
Occurrence. — Several examples of this beautiful 
species were taken on the Expedition, m the Vestfjord 
Stat. 255). the Borsangerfjord (Stat. 260), and the Tana- 
fiord (Stat. 261). attached to the tubes of Tubulana mdr- 
visa and SertulareUa Gayi . Moreover, the same animal 
was observed at Stat. 79, in the open sea west of the 
coast of Nordland, also at 2 Stations within the cold area 
(Stats. 33 and 190); depth ranging to 8(0 fathoms. lie 
species is not uncommon off our western and northern 
shores at a considerable depth, and has also been lately 
recorded from the east coast of North America.
