one in XXVII, and some in XXV and XXXI) I cannot find any reason to keep this species apart. 
Antipathes grandiflora, Silberfeld. The description is not very complete; the number 
of longitudinal rows is wanting, as well as the dimensions of the tentacles and such like. There is 
given a very good figure of the entire colony, which is very much like Antipathes arborea. 
According to Silberfeld the mode of branching is the same as in Paratylopathes atlantica Roule, 
which I have already discussed. The characteristics, described by Silberfeld, are not different 
from various specimens of Etiantipathes dichotovia. — Worth while is the occurrence of very 
large polyps between the normal ones, as is described in some Siboga-specimens. 
Antipathes pseudodichotoma Silberfeld. According to Silberfeld’s Plate II, fig. 4 a this 
colony is very much like various Siboga-specimens. In my opinion Brook gave enough species 
like this fragment, for instance Antipathes furcata Gray. — The characteristics, which may 
be found in the description, fit in the tabel. 
Probably the very incompletely described fragment of Silberfeld’s Antipathes n. sp. ? 
which has spines 93 p, in length, with a mutual distance of 300—500 p, placed in 4 — 5 
longitudinal rows, inserted at right angles with the axis with a slightly concave, slanting proximal 
side, also appertains to this series of species. The polyps are low, oval and sometimes trans- 
versally elongated to a rather high degree. The angle between the branches and the branch 
of lower order is acute. — Beside the discussed species there are various of the formerly 
described species, which may be considered as appertaining to Euantipathes dichotoma. Usually 
the description is too incomplete to permit a decisive opinion. Such species are e. g. : 
Antipathes gallensis Thomson and Simpson. The mode of branching is incompletely 
given. The regularly tapering branches are distributed irregularly so that the colony has a 
“shrub-like appearance, suggestive of the broom”. The shape of the spines, etc. is very well 
in accordance with Euantipathes dichotoma• there are 5 longitudinal rows. As to the polyps it 
is worth noting that the authors remark: “the polyps are elongated in the direction of the axis — 
this being specially marked on the smaller branchlets”; these words show how easily the so-called 
Antipathella- type is formed. — The form of the polyps agrees with those of Euantip dich. The 
words: “this species differs from any known form both in its mode of branching and in the arrange- 
ment of the spines” are not entirely right, since Brook describes Antipathes virgata as “corallum 
large, resembling the Broom”, (l; Synopsis of species pg. 98). — It is to be regretted that there 
are no figures, with the exception of a figure of the spines, which is but imperfectly serviceable. 
Antipathella ceylonensis Thomson and Simpson. The shape of the colony, except for 
the rare fusions, which however occur also in other species or specimens of the Euantipathes 
dichotoma-senes , is very much like that of Etiantip. dich. ; the angle between the branches 
varies from 6o°—90°. The branches are very slender and several cm. in length (up to 6 cm.). — 
The shape of the spines fit in the diagnosis of Euant. dich. ; the number of rows is 4; the 
polyps are described in a desultory manner; they are elongated in the direction of the colony- 
axis (cf. the remark in the discussion of the preceding species); the mouth is round and is situated 
on the top of a prominent cylindrical oral cone. The authors themselves call attention to the 
near approach of this species to Antipathella ? tristis Duch. The colonies of this species, figured 
by F. Cooper confirm this opinion, but his description is not detailed enough.
