Numerous small fragments (branches) and a rather large piece of a colony are found 
on this station. This last-named fragment is almost 0.5 m. in height. The stem (or the largest 
branch) is at first nearly straight with irregular curves, but ends in an irregular spiral, which 
makes 1 —1.5 convolution. The first part, ± 2.5 dm. in length, is branched, but the rest is 
unbranched and is 40 cm. long. The snapped — off branches, from the same locality, have the 
same length, 0.5 m. and even more (!), without bearing secondary branches. — On the branched 
part of the colony the branches are inserted at irregular intervals and on all sides of the axis, 
dheir mutual distance varies frorh a few cm. to 1 dm. and over; even on one place two 
branches are inserted immediately above each other, with their basal parts touching. — The 
angle between branch and stem is either 90° or 45 0 , but in most cases 90°. Afterwards the 
branch is curved towards the top of the colony. The branches are irregularly curved, but their 
top is wound spirally or sub-spirally. — The diameter of the black and shining axis is 2.5 mm. 
at the base of the colony-fragment and this value diminishes gradually towards the slender, 
elastic and thin tops of the branches. The entire fragment is firm enough to stand upright, 
without bending. 
I he spines (fig. 63) at the base of the fragment are at right angles with the axis, with 
concave sides and a very blunt apex 
(fig. 63a). The surface of the spines 
is very slightly granulated; their 
length, equal on all sides of the axis, 
is 1 15 p and their mutual distance 
is 650 p. There are 8—9 longitudinal 
rows, usually alternating in a quin¬ 
cunx, but sometimes shifted; the 
longitudinal rows are wound in a very 
steep spiral round the axis. On the 
top of the colony the spines (fig. 63^) are distally inclined with a concave distal side and a 
convex proximal side, but always with a blunt apex. The surface of these spines is almost 
smooth; their length is 125 p and there are 7 longitudinal rows, but with the same distance 
of the spines as on the colony-base. 
The polyps (figs. 64 and 65) are large and very prominent, while the intervening 
coenench\ ma is very thin so that the axis is dimly visible through it together with the spines. 
The interpolypar distance is 2 mm., and there is only one single series. — The oral cone is 
high, large and domeshaped, with a small round mouth. The sagittal tentacles predominate
