i mm.; sagittal tentacles 0.6 1 mm., lateral ones 0.4 mm. or less. Height of oral cone: o.z mm. 
its basal diameter 0.35 mm., and its top-diameter 0.2—0.25 mm., but sometimes broader than 
at its base while the tentacles may be also longer. I he sagittal tentacles are inserted at a 
much lower level than the lateral’ones. All the polyps are inserted in a single series! 
The specimen of station 164 is 13 cm. high, and consists of nearly 3 sinistrorsal spiral 
coils, with diameters of ± 5 cm. and a distance of 2—8 cm. Basal diameter of the axis: 1.1 mm

I he spines are arranged in 6—7 longitudinal rows, alternating in a quincunx. Their length is 
200 3 °° [ J -, different on opposite sides of the axis, which is more conspicuous at the base 
of the colony than on the higher parts. Long spines : at right angles with the axis ; short ones : 
clistally inclined. Mutual distance 700 — 750 p.. They are blunt cylindrical or conical, with a very 
rough top and a granulated surface, except the base of the spines (figs. 234, 235); on some 
parts the spines show concrescence to a rather high degree (fig. 236). The polyps are situated on 
the upper- and outward side of the coils; on 
the younger parts they form a single series, 
but on the older parts they are arranged 
in several rows (however fig. 238 is a part, 
which was rather near the top!). Interpolypar 
distance more than 2 mm.; sometimes they 
are separated by a greater distance; many 
young polyps alternate irregularly with the 
adult ones. Sagittal tentacles 1.5 mm. long, lateral ones 
°- 4—°-5 mm. On some parts, especially at the base of the colony, the dimensions of the polyps 
diminish and they are very like those of station 305 ; alternating with these polyps are others 
with accidentally less contracted tentacles. The oral cone may be also smaller and lower. On
