the lateral ones (the terrace, formed by these lateral tentacles and the oral cone is in the 
fig's. 15^ and 16 a given by a dotted line between the lateral tentacles). — Striking is the 
chalk-white colour of the lips, which also show many folds (fig. 15^); the mouth itself is rounded 
or sagittally elongated. The oral cone and the tentacles are covered with warts, with a light 
spot on their top (fig. 1 5^), which spots lie in alternating circles. The light spots occur through 
the disappearing of the darkbrown pigment which colours the entire polyp; somewhat more 
thinly distributed this same pigment colours the coenenchyma lighter, and here also (fig. 166) 
spots without pigment occur *). The form of the polyps indicates an Antipathes- character, while 
the spines have sometimes an Aphanipathes -character as Brook understands it, but not enough 
to place this species in the subgenus Aphanipathes. 
The primary branches of the colony-fragment of station 11 7 are of unequal length and 
are inserted in two rows, almost in the same plane; their further distribution is irregular. 1 he 
angle, they make with the stem, is about 6o°; they bear secondary branches, and these 
sometimes tertiary branches, which are inserted on one side of the colony, at right angles with 
the bearing branch or distally inclined. These secondary branches stand in two rows, which 
are at an acute angle with one another, but not very regularly. — T he length of the spines 
(fig. 17) is 150 [x ; their mutual distance is 125 p„; they are arranged in 5 longitudinal rows, 
which alternate in a quincunx. The top of the spine is granulated while the base is smooth 
(fig. 1 yb and c). On the older parts of the colony (fig. 1 yc) the spines are somewhat longer 
(180 v), more irregularly and sparingly distributed while the shape 
is more like a needle. Both sides of the axis differ principally in 
the form of the spines (blunt spines and aculeate ones). 
The specimen of station 250 is a fragment of a colony; the 
stem is 1.4 cm. in length, and bears two branches to the left and 
two to the right, all nearly in the same plane and at a mutual 
distance of ±3 mm., and further a few smaller branches.. The 
secondary branches, ± 1 cm. lang, which value varies to the 
length of the primary branches, are almost arranged in two rows; 
they are straight and they stand at an angle of 6o° with the 
primary branch; the angle between the two rows is obtuse. The 
tertiary branches have a length of 3— 5 mm. ; they are inserted 
under an angle of 6o°, and also in two rows which are at an obtuse angle with one another. 
These branchlets are more acute than in the specimens of stations 117 or 257, and more 
slender. — On the top of the branches the spines are small, but on a distance of 1 mm. from 
the top they are much larger. The form of the spines is as in fig. 15 a but the surface of the 
spine is slightly granulated; their mutual distance is 225 a. The five longitudinal rows alternate 
in a quincunx. The spines perforate the coenenchyma but not the polyps. On the stem the 
arrangement is not sc regular, the number of rows or fragments of rows is greater and the 
spines are more slender.
