for the longer spines, 50 p. for the smaller ones. Mutual distance for the longer spines 550 p, 
for the smaller ones 650 p; on some parts the latter are irregularly distributed and very 
crowded. The spines project very far through the coenenchyma as well as through the polyps, 
so that the polyps are scarcely to be seen separately with the naked eye. Young polyps are 
irregularly distributed between the adult ones. 
One of the specimens from station 310, 7.5 cm. high, is a basal fragment with a straight, 
slightly curved stem of 5.5 cm. followed by a sinistrorsal spiral-coil, with a diameter of 1.5 cm. 
Basal diameter of the axis 2 mm.; 1 cm. above the base some irregular swellings are found and 
a small crest. The base itself is a half-globe fixed on a plate with numerous dendritic extensions 
towards every side. The polyps are very degenerated, except the oral cone, which is low, and the 
mouth (fig. 222); the rest of the axis is covered with coenenchyma, with some thicker parts, 
which however are not very clearly to be recognised as tentacles. The oral 
cone and the mouth are sagittally elongated; the sagittal diameter is 0.5 
mm., the transversal one 0.3 mm. Interpolypar distance more than 1 mm. 
No cross-grooves are visible. — The larger and smaller spines are mingled 
on the same part of the axis, so that on opposite sides of the axis as 
many long ones as short ones may be found. But in the higher part of the 
colony, especially in the- spiral, there is an inclination to have shorter spines 
on the non-polyp-bearing side of the axis. In this part the larger spines 
are arranged, for a short distance, in 6 rather regular longitudinal rows, 
alternating in a straight or slanting quincunx. All the spinal characters 
are the same as in the specimen from station 305 ; the long spines are 
somewhat shorter (250 p.), but they project far through the polyps, etc. 
(fig. 222). 
The second specimen of the same station, 11 cm. high, without the 
natural base, is a sinistrorsal spiral, except the first 3.5 cm. which are 
straight. Diameter of the five coils: ± 1.5 cm. Between the 2 nd and 3 d coil is a sinuous part 
of 1.5 cm. The basal diameter of more than 1 mm. remains of an almost equal value; the broken 
top has a diameter of 0.6 mm. On the top-part there are 6 longitudinal rows of spines, and 
3 on the base, alternating in a quincunx. Slight irregularities occur through the presence of 
supernumerary spines. Mutual distance- is about 450 p. ; length 300 p. and 120 p. or slightly less. 
Surface very knobby, especially in the basal part of the colony (fig. 223), while the entire surface 
is roughly granulated besides (omitted in fig. 223); on the top of the colony the spines are more 
slender (fig. 224). The polyps are the same as in the specimen of station 305; they are found 
on those sides of the axis where the spines are the longest, so that the spines project through 
the polyps. Interpolypar distance 1 —1.3 mm. They are always arranged in a single series! 
The third specimen, grown through a sponge, has 3 1 / 1 regular sinistrorsal spiral-coils with 
diameters of 2— 5 cm.; the coils are somewhat oval. Height: 4 cm.; basal diameter 1 mm., 
gradually tapering towards the broken top (diameter 0.75 mm.). The polyps, which are violet, 
as in the 2 nd specimen, are like those of station 274 and 305. Sometimes they are larger and 
more prominent, especially in the higher part of the colony (fig. 227). Sagittal tentacles: 1 mm.
