2. Eubathypathes quadribrachiata sp. n. 
Stat. 122. i° 58'.5 N. i25°o'.5E. Banda Sea. 1264—1165 M. Stony bottom. 1 spec. 
This colony, in possession of a basal plate, is only 2.8 cm. in height. The unbranched 
part of the stem is 0.5 cm. and is slightly inclined forwards, while the branched part is inclined 
somewhat backwards. There are nine branches to the right and nine to the left, alternating 
regularly right and left; the distance in the same row is 2.9 mm. The length of the branches 
is in the left row: 6; 17; 8; 18; 14; 10; 6; 3 mm., and in the right row: 8; 29; 22; 20; 
14; 13; it; 7 mm. All branches are tolerably sound; the extremities are exceedingly long and 
slender. The angle between the right and left branches is nearly 180°; the branches are lying 
nearly in the same plane and are curved slightly forwards and upwards. They are inserted on 
the stem at an angle of nearly 90° by the lowest branches, but this value diminues to 
45 0 by the highest branches. — Beside these large branches there are also two rows of smaller 
ones, inserted on the front of the stem, 5 to the right and 7 to the left; the angle between 
these rows is only ± 25 0 . The plane which divides this angle is the same as the plane which 
divides the angle between the larger rows (fig. 10 a). — Their length is ± 5 mm., which by 
a. the middle ones increases to 10 mm. They are inserted on the stem 
under the same angle as the larger branches at the same level. 
Their mutual distance is the same as by the larger branches; the 
left row is inserted everywhere 0.5 mm. below the left row of 
larger branches, and the same holds good for both right rows so 
that the mode of branching is extremely regular (fig. 10 b). 
The basal diameter is 150 u. which increases to 255 4, to 
diminue regularly shortly before the first branches towards the top 
(75 l J ) which is broken 2.5 mm. above the last branch. The larger 
Fig. 10 . Eubathypathesqtiadribrachiata branches have a basal diameter of ± 135 p. (somewhat less by the higher 
sp ; D ; Pr °i ectl0n of the ^ ianches on ones) and their top is very thin; e. g. at a distance of 2.5 mm. from the 
ticai plane (£). top, its diameter is only 75 p.. — The small branches are much thinner. 
The base of the stem has short thick spines in three longitudinal rows, with a distance 
of 225 —300 p. in a row. Any other regularity is absent; sometimes a soon distorted and 
disappearing quincunx is shown. The thickest part of the stem is pretty well smooth, while 
the branched part has again well developed spines, 20 p. long (fig. 11). 
On the branches the spines are more obtuse; the longest ones (30 p.) are 
on the upper side of the branch; the shortest ones on the other side are 
15 u.. Their mutual distance is 150—180 p. and a slanting quincunx some¬ 
times appears. The spines are wholly smooth and never form ridges. The 
polyps are inserted on the upper side of the branches and on the front of 
the branched part of the stem. Notwithstanding the bad state of preservation the Eubathypathes- 
character is with a few polyps recognizable. The tentacles are very broad and short; their length 
is 225 —300 p.. The distance between the pairs of tentacles is always the same (675 p„). It is 
impossible to see further details.
