Polyps; 14 X- 
The polyps (fig. 18) are inserted only on the front of the colony; they are white 
with spots on low warts; on the coenenchyma these spots are not so apparent. — The length 
of the tentacles is 0.5 mm.; the diameter of the rounded oral 
cone is 0.3 mm. The mouth is small; the interpolypar distance 
is over 1 mm., but sometimes the polyps are more crowded. — 
Very rarely young polyps occur between the adult ones, but 
on the ultimate branches the polyps are smaller. 
The first specimen of station 305 is 6 cm. long and 
has a complete base with basal plate. The stem is straight for 
the first 1.5 cm., then curved laterally and afterwards straight 
again. On the curved part a straight branch is inserted, directed 
upwards and 2.75 cm. long. The stem, except the first straight 
part, which shows only broken stumps, as well as the branch bear 
secondary branches, alternating regularly right and left, with 
a mutual distance of 3 mm. in the same row, and a length 
which is about 7 mm. and which is shorter on the top 
of the colony; they are always inserted at an angle of67.5°. 
They lie nearly in the same plane as the stem and the large 
branch. Many branches bear one (seldom two, rarely three) straight tertiary branches, which 
may be inserted on all sides, always at an angle of 45 0 with the branch of lower order. They 
can attain the same length as the secondary branches. As 
their diameter diminishes swiftly, they are spineshaped. 
The spines (fig. 19) are arranged in 4 (—5) longi¬ 
tudinal rows, alternating in a quincunx, but sometimes showing 
irregular places. The length of the spines is 90 p. and 75 p.; the 
spines on the upper frontal side of the branches are more 
distally inclined (fig. 19 b) than on the other side (fig. 19 a). — 
Their mutual distance is 1 20 p„; the surface 
of the spines is smooth, except the top at 
the utmost (fig. igc). A few r doubled spines 
occur between the normal ones on the 
branches, while at the base of the branch 
the top of some spines is forked. The 
stem however has still principally normal spines; only at the base of the 
stem branched antlershaped spines appear (fig. 1 gd)\ their length increases 
with the degree of branching. The distribution of the spines on the base 
of the stem is entirely irregular; the surface of the spines is sometimes 
slightly granulated. 
The polyps (fig. 20) have nearly all disappeared; the rests occur on one side of 
the colony only. The oral cone is domeshaped, its diameter is 0.3 mm. and on its top lies 
the sagittally elongated mouth. On the stem the interpolypar distance is 1.25 mm. and on the
