of the spines is 155 y. and 120 y. on opposite sides of the axis; there are 5 longitudinal rows, 
alternating in a quincunx, with a mutual distance of 300 y„. — The base of the colony (fig. 58 
is on one side nearly smooth; the other side 
has spines of 165 y.; mutual distance 245 y. in 
the 4 (—5) longitudinal rows; they are more 
upright than on the other parts. The polyps 
(figs. 59, 60, 61) are very transparent (fig. 60), 
so that Brook’s Aphcuiipcithes- character is more 
conspicuous than would be the case when the 
polyps were more opaque (fig. 59). They are placed in a single series on the frontside of the 
colony; sometimes they are somewhat shifted. The ten¬ 
tacles are overlying the oral cone, which in this manner 
is inconspicuous. The sagittal tentacles are inserted at 
nearly the same level as the lateral ones ; their length is 
subequal (0.35 — 0.5 mm.). The interpolypar distance is 
1.6 mm. at the utmost. The transversal groove is often 
visible; some young polyps occur between the adult ones. The longitudinal groove at the back 
of the axis broadens very much towards the top of the branches 
(fig. 61). — The following specimens are entirely or nearly 
without polyps : 
Station 240. Complete slender colony. Stem 3.5 cm., 
curved in a half-circle; 12 straight branches, all at right angles 
with the axis, not in a plane; length rh 1 cm. (max. 2 cm.). 
Secondary branches ditto; length a few mm. to 0.5 cm. Spines: 
5 rows and quincunx; distance 330 y, to 390 y.; length 70 y. ; shape fig. 4.7 a, but the distal 
side is concave and at right angles with the axis. The polyp-remains are of the type of 
station 184; the interpolypar distance is 1.25 mm.; young polyps occur between, the adult 
ones. — Station 305. A rather strong colony; straight stem; branches on all sides; secondary 
branches principally in a plane. All branches curved or sinuous. Ultimate branches 3 — 5 mm. 
Rare fusions occur between the primary branches. Angle 6o° to nearly 90°. Mutual distance 
1- — 6 mm. Spines as fig. 50; length 50 y. on all sides; distance 180 y. ; 5 longitudinal rows. 
A large part of the colony is enveloped in a sponge-tissue with many spiculae ; in the cavity, 
formed by this tissue, shut on all sides, sits a colourless Decapod. The mode of branching is 
on first view not so very like that of the other colonies, since the shape of the colony, especially its 
marked thickness, forms a transition towards the former genus Arachnopatlies. — Station 119. 
Irregularly curved stem of 5 cm. Branches at angles of 45 0 to 90°, on all sides; length 
1—5 cm., curved. Straight secondary branches of 5 mm., nearly at right angles with variable 
distance. Diameter of stem is 0.5 mm. and diminishes regularly. The entire colony is very 
much like that of station 305 minus the fusions. Spines as fig. 50, but at right angles with 
the axis; length 85 y, distance 330 y,; 6 ( — 7) longitudinal rows and a slanting quincunx. — 
Station 80. Two specimens, one branched in a plane, the other one not. In one specimen the
