Beskrivelse. Legemet er (se PI. XX, Fig. 1 og 2) 
'-hnimlig kort og undersretsigt, med Capitulum betydelig

sannnentrykt fra Siderne. Hvad Legemets Stilling augaar,

Selve Capitulum er seet fra Siden (Fig. 1) at aflang

Specific Character. — Capitulum oblongo-rhomboidal, 
omewhat expanded towards end, with apex short and 
xlaced below axis of body. Valves smooth, without immi- 
nent sculpturing, and distinctly defined by narrow, inter- 
ring cutaneous parts. Keel pronounced angular, with 
listinct umbo. Tergal segments inequilateral-triangular, 
, v ith occluding margin shortest. Shields — without distinct 
unbo _ irregular-quadrilateral. The upper lateral segments, 
veil -nigh equal in breadth to the shields, with distinctly 
meeting umbo. Basal segments differing in size, dorsal 
[ar Lt, at base slightly projecting, median pentagonal, 
ventral smallest, in form irregular-quadrilateral. Rostrum 
wedge-shaped, broader at base. Peduncle short, sharply 
bent, and covered over with large imbricate calcareous 
scales. Outer investing membrane smooth. Colour a snowy 
white; viscera orange, shining through the integument. 
Length reaching 13’™. 
Locality. - Stats. 33, 79, 190, 255, 260, 261. 
Remarks. — No detailed description of this form 
havin' 1 ' as yet been furnished, I give one here, chiefly to 
serve for comparing the animal with the recently discovered 
species described below. From the species previously ob- 
served in Northern Seas, viz. Sc. vulgare Leach, it may at 
once he distinguished by the snow-white colour of the shell 
anil the smooth outer membrane; also by its ar less pro- 
jecting apex, the form of the rostrum, and the much 
larger calcareous scales on the peduncle. 
Description. — The body (see PI. XX, %«■ !» *) 
is rather short and thickset, with the capitulum considerab y 
longer and broader than the peduncle, and, as usual, greatly 
compressed from the sides. As regards the position of the 
? . its mo de of attachment to the different submarine 
obiects is invariably such, that the capitulum takes an 
oblique downward direction, with the ventral margin turned 
more or less in towards the object serving for the attach- 
meIlt The capitulum itself, viewed from the side (fig. 1), 
is oblongo-rhomboidal in form, and somewhat expanded
