Antipathella? tristis Duch. (description by Brook). The description of this species shows 
many vague data, but the delicacy of this species, the very slender branches, the not frequent 
fusions (Brook says: “they are more properly defined as adherences”) are not in disaccord 
with the type of Euant. click. The spines, figured by Pourtales, are also like those of 
Euant. dick, especially like the somewhat more heavily built spines of IV and X from the 
tabel. — The polyps are very vaguely described. 
Some other species (viz. some of Brook’s Aphanipathes- species) might also be included. 
Intentionally I have said that all these species should be united for the present 
for in many cases a decision could only be given by the examining of more entensive material. 
But the here-given assembling of many former species into one is only meant as a proof of 
a possible sifting of the numerous data. — Without much trouble many new species might be 
created, and the trouble would be as small to arrange the various specimens in varieties as is 
briefly pointed out in what follows. The var. a Schultze, containing Schultze’s specimen and 
XVII, would be characterized by the polyps of Schultze’s PI. XIV fig. io and my fig. 53^, 
mouth sagittally elongated, spines at a mutual distance of ± 300 y, with their distal side at 
right angles with the axis, and a colony as Schultze’s PI. XIV fig. 14. — Schultze’s var. [3 
with a colony as Sch.'s PI. XIV fig. 12, polyps as Sch.’s PI. XIV fig. 11, spines at a mutual 
distance of 400 y. and their distal side also at right angles with the axis, would Contain 
Schultze’s specimen and IV and XXIV. — Specimens VI and XXVII could appertain to a 
var. verticcilis with a type of polyp very much like var. a, but with their branches at right 
angles with the stem or with the branch of lower order. Antipathes furcata Gray, with the dia¬ 
gnosis given by Schultze (11; p. 91) makes a var. Grayi together with Antipathella gracilis 
Gray (description by Johnson), while Antipathella Brooki with its fusions makes a var. symphysa. 
A var. virgata with a type of polyp very much like var. a, and an angle of 30° (— 45 0 ) 
between the brandies, contains Antip. virgata Esp., Antip. aenea v. K., Antip. dichotoma 
Pall., Antipathes gracilis v. K., Antipathes viminalis R. 
A var. parallela with type of polyp as var. a, long spines, an angle of 30° between 
the branches, which lie in a single plane and which are in their distal part subparallel with 
the stem, could be made by XX. 
Comparing the characteristics of Euantipatlies glaberrima Esper (emend.) with the data in the tabel 
of Euantipatlies dichotoma, a very great concordance is found, in fact so great that at first 1 considered 
to combine both species. But at further thought it appeared to me more desirable to keep both species asunder, 
although not so far as other authors did in view of the sparingly distributed spines and the anatomical 
structure of the polyps. Although there are no specimens of this species among the Siboga-material, here 
I will give a critical review of this species, together with all other Leiopathes- species.
