Young polyps are irregularly distributed between the adult ones; some spines are dimly visible 
through the coenenchyma. The length of the sagittal tentacles is 0.45 mm., of the proximal 
lateral ones 0.3 mm., of the distal lateral ones 0.175 mm. The height of the oral cone is 
0.25 mm. All these dimensions may be larger or smaller but always in the same proportion. 
In the young polyps the preponderance of the proximal lateral tentacles is already visible 
(fig- 45^? to the right). — I he second specimen of the same station has fork-angles of 45 0 or 
upwards of 6o°; there is no increase of diameter above the base. 
I he colony of station 7 is 9 cm. in height, and more slender and thinner than the 
colony of station 204, but otherwise branched in the same manner. All branches are sinuous ; 
they often exceed the stem in length. The fork-angle is 45 0 ; the branches are curved towards 
the opposite side as the branch of lower order. The diameter of the axis increases distally and some 
branches show the same phenomenon. All branches show an inclination to lie in a single plane. 
The polyps are inserted on one side of the colony. The spines are distributed in 4 longitudinal 
rows and a straight quincunx. Length 60 y (somewhat shorter on one side of the axis); 
mutual distance 240 y. Shape of the spines: fig. 42. The polyps are the same as in station 
204: the intertentacular distance is 1.5 mm., which value varies on various parts of the axis. 
I he colony of station 50, 10 cm. in length, is branched in the same manner, with 
fork-angles of 45 0 —6o°. Various branches show an initial increase in diameter. Polyps and 
spines are the same as in stations 7 and 204. Intertentacular distance: 1.5 — 1.6 mm. Spines 
in 5 longitudinal rows and a slanting quincunx. Length 60 y- mutual distance 270 y. 
One of the specimens of station 144 is a fragment, branched on all sides, with the 
branches always nearly at right angles with the branch of lower order. The branches are some¬ 
what curved, sometimes changing of direction at an obtuse angle. The mutual distance of the 
branches is a few mm. to 1 cm. and more. The spines (fig. 4 6a) are smooth, triangular and 
at right angles with the axis or somewhat inclined. The spines 
on opposite sides of the axis differ in length and sometimes 
one side of the axis is nearly smooth ; the longest spines do 
not coincide precisely with the polyp-bearing side of the axis. — 
There are 6 longitudinal rows, sometimes forming a quincunx, 
but usually showing a great variability in the mutual distance 
of the spines, and also in the course of the rows itself. On 
an average the mutual distance is 225 y. and their length 
60 y. — The polyps (fig. 46^) are inserted in a single row, 
without giving preference to a special side of the colony. The 
oral cone is low with a small round mouth. The length of 
the sagittal tentacles is 0.35 mm., of the lateral ones 0.3 mm. 
The intertentacular distance is 1.25 —1.5 mm. — Here and 
there a very large polyp appears (fig. 46^, at the base of 
the branch), just as is described in other specimens. The 
spines are visible only through the coenenchyma. 
The second specimen is a complete colony, 4 cm. in height. The stem is curved and
