diameter and 35 cm. high; so the spiral is rather steep. Warts and secondary curves are found. 
The spines are numerous wart-like elliptical knobs, irregularly distributed, although parts of 
longitudinal rows are to be found; mutual distance ± 300 p.; there are 24 fragments of rows 
to be estimated on the toppart, but at the base this number increases. 
It is not possible to doubt that these specimens belong together, in view of the shape 
of the colony, the dimensions of the spiralcoils, the shape and the dimensions of the spines, 
which characters are all of them subequal in all the specimens except for the last one which 
has double the number of longitudinal rows of spines, so that it may be considered as a variety 
(var. polysticha ) ot the normal type. The very great likeness between Eucirr. Rumphii and 
Stichopathes poartalesi Br. in point of the polyps, does not hold good for the colony, etc. In 
my former publication on this genus I reviewed the characters of the Siboga-specimens and of 
Stick, pourtalesi in a tabel (cf. 22, p. 37); the data are deduced from the spines figured by 
Pourtales, but this fig. is not so clear as to permit a reliable estimate. Although Stick, pour¬ 
talesi and Eucirr. R. are very like each other I have not combined them as in my former 
publication, since the examination of the other genera made it more probable that this Sticho- 
pathes- species had to be united with Stichopathes gracilis Gray (cf. the critical review of the 
formerly described Stichopathes- species), but both species are surely very nearly related. — I 
have named this species after Rumphius, since I deduce from the figures and descriptions of his 
P'almijuncus vulgaris that it is possible that he had a specimen of the here described species. 
However the shape of the colony and the basal diameter are not clearly given, but the figured 
colony is very like the basal parts of the Siboga-specimens. Its base shows a reduction of the 
polyps since Rumphius remarks that the “clunne, taaie, schors”, which covers the axis is “ruiger" 
in the upper half of the colony than in the basal part. — The colony described by Thomson & 
Simpson as a possible new species of Cirripathes has at first a sinuous stem but is afterwards 
wound in three coils of a diameter of 7 — 10 cm. with a distance of 7—10 cm. between the 
coils. The spines are ± 100 p. long, near the top of the colony; the number of longitudinal 
rows varies from 20 at the base to 9 at the top, and so is intermediate between Eucirr. Rumphn 
and its var. polysticha. The spines are papillose. Although the polyps are absent, in my opinion 
T. & S.'s specimen ought to be joined with Eucirr. Rumphii. 
Diagnosis: 
Colony : base upright and sinuous or a very steep spiral; the upper part 
is a regular sinistrorsal spiral, the coils of which may be slightly secondarily 
sinuous; their diameter is a few dm.; sometimes warts on the axis; axis tapers 
gradually. Rarely beginnings of a branch. 
Spines: conical with rough, blunt apex; at right angles with the axis or 
slightly distally inclined; of equal length on every side of the axis (± 120 3); 
mutual distance more than 300 u .; 12 regular longitudinal rows. 
Polyps : darkbrown; tentacles lying against and wound about the axis, 
(or in a group upright on the axis); oral cone sagittally elongated, with 
vertical stripes and bands; sagittal tentacles 4.5 mm., lateral ones ditto 
or slightly shorter; interpolypar distance max. 6 mm.; arranged in one
