375 [ J - There are three longitudinal rows without further regularity. The longest spines (35 y.) are 
to be found at the front of the axis. Higher at the axis again long ridges occur, on which the spines 
are as distinct as on the other parts of the axis. On the branched part of the stem there are 
4— 5 longitudinal rows and the type of spines is as in fig. 7 c. — On the branches the long 
spines (45 .a) are formed as in fig. 4 b and the short ones (30 y.) as in fig. 7 c. Their distance 
varies from 
225- 
>oo y.

a Spines with elongated base, on 
the distal part of a branch; b top 
part of a branch; a 52 X- 
; there are four longitudinal rows, without further regularity. On the 
distal part of the branches the bases of the spines are very much 
elongated, as a beginning of ridge-forming (fig. 9 a). Also the spines 
are distally inclined. The spines remain free from one another. The 
longest spines are inserted on the upper-frontal side of the branches. — 
At the top-part of the branch the very great width of the axis lumen 
and its very- thin wall is striking (fig. 9 6 ). 
Both specimen of station 74 show the same curves of the 
stem as the specimen of station 211. One is without polyps and without 
the natural base. The unbranched part is 3.5 cm. the branched part 2.5 cm. The basal diameter 
of 220 u diminues gradually towards the top which ends 2.5 mm. above the last branch. There 
are 5 left and 4 right branches. Their length is in the right row: 3.5; 4; 2.9; 2.2 cm., and 
in the left row 3; 1.8; 1.5; 2.4 cm. — The distance in a row is regularly 5.5 mm. All the 
right branches are inserted 0.75 mm. above the left branches. The angle between branch and 
stem is ± 6o°; the angle between the branches of the first pair is 67.5°, but with the second 
pair already 105°; this value increases with the following pairs to 120°. 
On the unbranched stem there are four longitudinal rows of spines, with a distance 
between the spines of 225—375 y. and no other regularity. The form is as fig. 7 b but on 
the branches the spines are more acute (fig. 4 a). The length of the spines (25 y.) is subequal 
on opposite sides of the axis. 
The other specimen of this station has polyps and a basal plate fixed on a branch, dark- 
brown, gradually lighter towards the border, round (1 cm. diameter). The unbranched part is 10.5 cm. 
the branched part is 4.5 cm. The basal diameter is 300 y., increases to 385 y. after 2.5 cm,, 
and gradually diminues towards the top, 0.5 cm. above the last branch. All right branches are insert¬ 
ed regularly 1 mm. above the left branches. The distance in a row is 5.5 mm., increasing slightly 
by the middle branches. The length of the branches is in the right row: 4.6; 5.3; 5.8; 5.9; 5.5; 
4.7; 1.5; 0.7 cm., in the left row: 4.8; 5.3 ; 5.7; 6.4; 5.9; 5.1; 3 ; i. i cm. — The angle between 
the first pair is 45 0 ; between the second pair: 90°; this value increases to 120° by the last pair, 
where the branches are curved backwards till they lie in a plane. — The angle between branches and 
stem is always 6o°. The first pair is directed distally and the tops curve together; the other 
branches are curved first distally and forwards and then towards the base and backwards; this 
last curve is stronger as the branch is higher inserted. 
The base of the stem has a few scattered spines, but a little higher the stem is totally 
smooth; only it is covered by grooves and folds in steep spirals. A short distance before the 
branched part the spines appear in 4 (— 5) longitudinal rows ; their distance in a row is 300 — 525 y.; 
the type is as fig. 8^, somewhat longer on the front of the axis. On the branches are 4 rows
