The colony-fragment of station 64 is a stem of 4 cm., snapped off on both ends and 
with a diameter of 150^: The single branch, inserted at an angle of 6o° is repeatedly branched; 
all branches are inserted at angles of45°, except one secondary branch which is inserted almost at right 
angles. All branches are very slender and curved, and they do not lie in a single plane. The 
length of the branches is 8—9 cm. and their mutual distance is 1.75 cm The ultimate branches 
are all at the same distance one from the other; their length is 3—4 cm. — Spines in 4 
longitudinal rows with a straight or slanting quincunx. Their shape is nearly the same as in the 
specimens of station 302 (fig. 32). Surface is smooth; length 30 p.; mutual distance 300 p.. On 
the stem they are arranged somewhat less regularly. 
The polyps (fig. 33) have their distal lateral tentacles usually of equal length as the

proximal pair; rarely a slight difference is visible (fig. 33^ and c). The length of the tentacles 
is 0.3—0.375 mm.; the intertentacular distance is 1.6 mm. The oral cone is low and rounded; 
the mouth is very small and nearly not to be discerned. In all other respects the polyps are the 
same as in station 302. Mesenterial filaments are not visible. 
The two very slender, thin (the basal diameter is only 105 p.) and limp colonies of station 193 
are branched in the same manner. The branches, inserted on a mutual distance of ± 3 cm., 
are 3—-8 cm. long, and the fork-angle is ± 45 0 . Polyps and spines are the same as in station 302. 
The type of fig. 30^ occurs as well as the type of fig. 31. Also the very swollen polyps, 
described for the specimens of station 302, can here be found (fig. 34^). The tentacles are 
covered with warts. The spines have a more elongated base on the younger branches (fig. 34^). 
On one of the colonies the tentacles are more slender (fig. 35«), possible a result of 
the preservation. — In the bodywall or in the tentacles often bubbles occur which are transparent 
with a darker nucleus; they make the polyps look swollen and distorted (fig. 35^ and c ). 
We easily see that these bubbles are not lying in the gastral cavity, but in the wall itself, 
between ectoderm and entoderm; I hold them to be of parasitic origin. — The difference
