65 [x and 20 tx (fig. 4 c) • the distance varies from 375—525 J a. Many branch-tops have 
5 longitudinal rows with many quincunxial parts and the form of the spine is somewhat more 
hooked (fig. 4 d). 
The stem of the specimen of station 211 is in its unbranched basal part curved for¬ 
wards, while the branched part is curved backwards and the top again curves forwards. The 
unbranched part is 10.5 cm.; the branched part 8 cm. The basal dilation is rounded. The 
basal diameter is 550 p. which increases to 650 tx on a height of 4 cm. and remains so till 
the first branches, after which the diameter diminishes regularly; the top ends 7 mm. above 
the last branch. — The branches are long and slender; the lowest are at right angles with the 
stem, while the higher inserted pairs make a more acute angle with the axis. All branches are 
curved distally first but their tops are again curved towards the base of the colony. The angle 
between the first pair of branches is 22.5 0 , which value increases regularly for the higher pairs, 
to nearly 90° for the last branches. — There are 11 branches in the left row and 8 in the 
right row, and they do not form such regular pairs as with the specimen of station 88. The 
first left branch is inserted 2.5 mm. lower than the first right branch; the distance between the 
branches is for the left row:'6.5; 5; 7.5; 3.5; 7; 6.5; 6.25; 5.5; 6.75 mm. and for the right 
row: 10; 11.75; 7; 10.25; 8.5; 7; 7 mm. The length of the left branches is; 6.5; 7.25; 
7.67; 8; 9; 10; 9.25; 9; 8; 6.25; 2 cm., and of the right branches: 8.5; 9; 9.25; 10; 8.5; 
5.5; 3.25 cm. The branches are inserted at right angles with the stem; first they are distally 
curved and then they are directed towards the base of the colony. — The angle between the 
first pair is 90°, and this value increases swiftly up to 150° by the last pair. While these last 
branches are somewhat curved backwards, they lie nearly in one and the same plane. 
The spines are sharp and conical; even the basal part of the stem shows the spines 
well-developed and nearly normally distributed; the distance in one row is here very variable, 
from 225—300 p. and over. The back side of the stem is almost smooth, except in the younger 
top-part where the number of longitudinal rows is four, with regular quincunxial arrangement, 
and a distance of 255 p. between the spines of a row. On the branches there are 3—4 longi¬ 
tudinal rows forming a slanting quincunx. The distance between the spines is 300 p.; the length 
of the spines on the not-polyp-bearing side as well as on the polyp-bearing side is 45 p„ The form 
of the spines is as fig. 4 b but sometimes somewhat more sharpened. The young spines at the 
top are very short: iop.. 
The polyps (figs. 5 and 
6) are inserted on the 
front of the stem and 
on the upper-frontal side 
of the branches, always 
in one series. The un¬ 
branched part is with¬ 
out polyps. — The sagittal tentacles are inserted at a somewhat lower level than the lateral 
ones and all the tentacles are inclined distally (figs. 5 and 6); the distance between the pairs 
of tentacles is always 2.75 mm., but towards the top the pairs are more crowded and by the
