At Basalstykkerne ud marker de dorsale sig ved en 
ganske ussedvanlig Form, idet de til liver Side af Kjplens 
basale Parti h sever sig i Form af en kornlignende opad- 
boiet Fortsats, hvad der bar givet Anledning til Artsbe- 
uaivnelsen (se ogsaa Fig. 10). De er ligesom de 2 pvrige 
Dasalstykker forsynede med sterdeles tydelige radierende 
biier. De midterste Basalstykker ligner i sin Form mest 
saaune hos Sc. Stromii, men skiller sig derved, at de i 
fidten danner en stserkt fremspringende umboformig Eor- 
heining. De ventrale Basalstykker er meget mindre end 
c e ovrige og afsnmlnes kileformigt mod Rostrum. 
Dette sidste er (se Fig. 9) meget lidet og rudimen-

The shields are comparatively broad, with the lateral 
margin shorter than the others and the apical corner pro- 
duced to a sharp rostral projection, jutting over the basal 
margin of the tergal segments. 
The upper lateral segments are appreciably smaller 
than the shields, and oblique, almost rhomboidal, in form. 
with a distinct, subcentral umbo. 
Of the basal segments, the dorsal present a most 
unusual aspect, rising, as they do, from either side of the 
basal portion of the keel as corniform, upcurvmg probations, 
a character that suggested the specific designation (see 
too fig. 10). They are marked, in common with tlm 2 
remaining basal segments, by exceedingly distinct radiating 
lines. The median basal segments exhibit in their form 
greatest resemblance to those of Sc. Stroma, but differ by 
forming in the middle a strongly projecting umbo-shaped 
prominence. The ventral basal segments are much smaller 
than the others, and taper wedge-like toward the rostrum. 
The latter (see fig. 9) is very small, and rudimentary, 
scarcely at all longer than broad, and well-nigh quadrate, 
resembling most in form Sc. vulgare. 
The peduncle is short, hut little more than half as 
long as the capitulum, and greatly constricted at the base. 
It exhibits a sharp inflexion, precisely similar to that in 
Sc Stromii, and has, in common with that form, a dense 
covering of large, regular, imbricate calcareous scales. 
The outer investing membrane, as in Sc. Stroma and 
Sc angushm. is quite smooth and without spikelets. 
Colour white, with the orange-coloured ovaries shining 
through the integument.

Occurrence. — A number of examples belonging to 
is species were collected on the Expedition, at 3 different 
ations Of these Stations, one’ (Stat, 124) lay in the 
act of ocean west of the coast of Nordland, the other 
Stat 267) in the Barent’s Sea, and the 3rd (Stat. 359) 
est of Spitsbergen; depth ranging from 148 to 416 fatb- 
its Two of the Stations were in the cold area, and the 
rd ' lay on the boundary. The specimens came up attached 
, Hydroidse and Polyzoa.
