being a Stichopathes- species. 1 hence I have identified my specimens with Silberfeld’s species, 
but now as an Euantipathes. I he name, which ought to be Euantipathes japonica cannot be 
used, since Brook has described an AntipatJies (= Euantipathes ) japonica , with which Silberfeld’s 
species is not identical. — In view of the great length of the branches I propose the name 
longibrachiata . 
Although there are points of conformity between this species and Euantipathes dichotoma , 
I will keep this species intact, in view ot the form of the polyps, and especially of the enormous 
length of the branches, their shape and the deviations in the spines. 
Diagnosis: 
Colony : Black, branched in all directions; branches inserted at an 
angle of 45 or 9o°, at a mutual distance of a few mm. to more than 1 dm. — 
Increase of diameter above the base. Branches very long and slender, up 
to nearly 1 m. long, unbranched, sinuous and partly wound in a spiral. 
Spines: Blunt, smooth or slightly granulated, at right angles with the 
axis, with concave sides, or (in the higher parts of the colony) distally 
inclined with concave and convex sides. Length 115 — 142 p., mutual distance 
650 a; on the younger parts 6 — 7 rows, on the older parts 8 — 9, with a 
quincunx. 
Polyps: Large and conspicuous; in one series; domeshaped oral cone 
with small round mouth. Proximal lateral tentacles predominating'. Sagittal 
tentacles at a lower level than the lateral ones. Inter poly par distance 2 mm. 
Length of the tentacles 650 p to 2,5 m.m. 
Former habitat: Silberfeld Enoura-bay (Japan). 120M.; 34°58 / N. i39°42 / E. 144M.

I he colony of station 299 is snapped off near the base; there is no special principal 
branch or stem, for there is a great number of equivalent branches, all of them densely branched 
in all directions, with numerous fusions between them, resulting in an entangled mass of branches. 
The mutual distance oi the branches is very short, 0.5 cm. at the utmost. — The branches 
taper swiftly so that, especially in the basal half of the colony, many spineshaped branchlets 
appear. All branches are somewhat curved and usually the convex side of the branches bears 
most of the branches of higher order. The angle between the branches varies from 6o° to 90°. — 
1 he height of the colony is 15 cm., its breadth 15 cm., and its greatest thickness 10 cm. 
One side ot the colony is flat, the other side is rounded, so that a section of the colony is
