is very deep and broad, and visible from 1.5 cm. above the basal end to 0.75 cm. from the 
top. On this point the groove becomes more and more shallow and indistinct.

One of the specimens of station 299 is a fragment in spirit, while the other specimens 
from this and the following stations are dried. — This fragment, 55 cm. long, is one spiral 
coil (the top-one) of a sinistrorsal spiral colony; diameter of the coil: 18 cm., basal diameter of 
the axis 1.6 mm. The polyps are not so well preserved as in the former specimen but the 
type is unmistakably the same. In the top-part the polyps are uniserially arranged but lower 
down it is very obvious that they are not placed in a single series, although they are found 
on one side only of the axis, or more precisely on two thirds of the 
circumference of the axis; it is not to be decided whether there are 
distinct longitudinal rows. The cross-grooves between the polyps are 
not always at right angles with the axis; they are especially con¬ 
spicuous at the back of the axis, where the fine longitudinal groove 
is also visible; between the larger cross-grooves numerous fine ones are visible. The coenen- 
chyma is thinner than in the preceding specimen, and so the longitudinal groove at the top 
is much less deep and broad. The spines (fig. 249) are slightly distally inclined; their top is 
covered with rough knobs; their length, subequal on every side of the axis, is 105 p, and their 
mutual distance 300 p. There are 12 — 13 longitudinal rows, alternating in a straight or slanting 
quincunx, but sometimes irregular. 
One of • the dried specimens of this station is 4.5 m. long, fixed to a piece of coral the 
irregularities of which are followed by the basal plate, which is finely stratified. I he entire 
colony is covered with polyps; spines and rests of coenenchyma are found even on the 
surface of the basal plate. The basal diameter of 10 mm. diminishes regularly towards the 
broken top (diameter 1.3 mm,). The first 1.20 m. are upright and slightly irregularly sinuous, 
with indications of a very steep spiral in some parts; the curves have smaller secondary bends. 
The rest of the colony is a very regular sinistrorsal spiral, the coils of which diminish in 
diameter towards the top from 23 to 15 cm. (the 6 th coil). In a free-hanging condition the 
distance between the coils is 1 dm. The axis is very elastic; knobs or warts or swellings are 
entirely absent; however it is possible that the coenenchyma-covering makes eventual slight 
irregularities invisible. At the broken top the axial canal has a diameter of only 0.5 mm. 1 he 
coenenchyma is dirty-greyish-brown, and bears numerous dried, shapeless, darkbrown polyps, 
which, near the top, are arranged in precisely the same manner as in the preceding specimen, 
and which are also the same in shape, although changed by the drying process. They cover 
nearly three fourth of the circumference of the axis ; the rest is smooth. I his smooth side of
