Fig. 196. Stichopathes aggregate/, sp. n. a Polyps on the 
top-part of the colony; Jone of these polyps; a 7.6 Xj & 14 X- 
The polyps (figs. 195^, 196), placed in a single series, are very well preservated and 
strikingly white, not transparent. The interpolypar distance is 2 mm. or more; in the top-part 
of the colony they are, as usually, a little more crowded. 
Alternating rather regularly with the adult polyps young 
ones occur. The tentacles are short, cylindrical, thick; 
the sagittal ones are 0.35 mm. long, the lateral ones 
0.3 mm. They may be all of them distallv inclined 
(fig. 195 d) or they are upright on the axis, or with 
their tops inclined towards each other, however without 
covering the oral cone. Since the polyps are visible as little cushions on the axis, and in this 
manner are thicker than the interzooidal areas while the polypar diameter gradually increases, 
the colony is very like a series of spindle-shaped thickenings (fig. 196^:); in the thinnest part 
the cross-groove is visible. The polyps are principally so very promiment through the oval, 
transversally elongated oral cone, the diameter of which is 450 u.. The mouth is small (fig. 
1950?) with a diameter of 75 p. — The longitudinal groove along the back of the axis is also 
clearly visible. 
This type of polyps is very much like the polyps of Eiiantipathes dichotoma (cf. especially 
the polyps of Antipathes furcata figured by Schultze in his Valdivia-Antipatharia PI. XIV, 
figs. 10 and 11), as well as the shape and other characters of the spines, while the microscopical 
anatomical details are in many points concordant (cf. the anatomical part). I have called this 
species aggregata , while the name of Stick, dichotoma would be less appropriate, but the 
probability is very great that we have a young, still unbranched specimen of Euantipathes 
dichotoma , which would be another demonstration of the vague limit between Indivisae and 
Ramosae. The diagnosis is as follows; 
Colony: irregularly curved, slender; length 12 cm. with a basal diameter 
of 1 35 E 
Spines; smooth, triangular, acute, at right angles with the axis. Subequal 
in length; 45 p.; mutual distance 300 — 375 p; 5 — 6 longitudinal rows. 
Polyps: spindle-shaped; interpolypar distance 2 mm. or slightly more. Ten¬ 
tacles cylindrical; sagittal ones 0.35 mm. lateral ones 0.3 mm. Large oval, 
transversally elongated oral cone, with small round mouth.

I his colony is 18.5 cm. long, upright but slightly curved. The base is complete, but 
it is fixed on the underground without broadening into a basal plate. The basal diameter of 
1.2 mm. diminishes regularly to a height of 7 cm., where the diameter suddenly diminishes from 
more than 1 mm. to 0.65 mm. (fig. 200). On a height of 1 cm. and 2 cm. above the base 
the same fact takes place but to a minor degree. On a height of 11.5 cm. there is a fourth 
striking diminuition in diameter. The top is slender.
