Synonymy.
Differences between
my description and
those of preo ioas
authors.
Proportion between
males and femalcs.
Remarks: — The species dealt with by me above is described from speci mens cauglit
off the west coast of Sweden. It seems to me practically certain that it is identical with C.
obtusata, G. 0. Sars, 1865. It is true that the original description of the latter species is very
incomplete, but for niuch the same reasons as have been put forward on p. 631 above in the
case of C. elegans it appears to be quite sufficient for certainty of identification.
This species was at first referred by G. 0. Sars to the genus Conchoecia; in a later work
by this writer, 1890, however, it was transferred to the genus //alocypris. This alteration,
presumably made under the influence of a statement in the same direction by C. CLAUS, 1874 a,
p. 178, and only explicable, of course, as being due to G. 0. SARS’s slight knowledge of the
differences between these two genera, has quite correctly been set aside by other writers.
The following names included in the list of synonyms given above are without descriptions
and verificatory figures: G. O. Sars, 1890; E. VANHÖFFEN, 1897; 0. Nordgaard, 1899; P. T.
Cleye, 1903; P. T. Cleve and O. Pettersson, 1903; Tu. Scott, 1905; C. H. Ostenfeld,
1906; E. KOEFOED, 1907; C. H. OSTENFELD and C. WESENBERG-LUND, 1909; C. APSTEIN, 1911;
E. JÖRGENSEN, 1912 and K. Stephensen, 1913. They are included in the list in question in
spite of this, because they all refer to finds from regions in which this species is known for
certain to exist. I was able to verify one of these statements myself by a re-examination of the
original material; this was that of P. T. Cleve, 1903 ( P. T. CLEVE and O. PETTERSSON, 1903).
G. S. Brady and A. M. Norman’s description, 1896, is based on some specimens from
the coast of Norway, determined by G. O. Sars.
G. 11’. MÜLLER’s description, 1901, which is apparentlv based on the same specimens as
formed the basis of E. VANHÖFFEN’s information, 1897, may be said to be sufficient for certainty
of identification.
It may also be considered as quite certain that this was the form dealt with by V. Våvra,
1906. Are we to refer the most southerly finds in this author’s work to this species as well?
On the other hånd it did not seem to me proper to include in the above list of synonyms
Conchoecia obtusata, G. S. Brady, 1868 b, p. 470 (- the same writer, 1868 a, p. 128). The
figure, pi. XLI, fig. 9, with which this author illustrâtes this find shows an organism of so peculia r
a type that it seems to me quite impossible to identify it (= Ostracod?). This uncertainty on
the part of this writer has also prevented me from including C. obtusata, G. S. BRADY and
l). ROBERTSON, 1872, p. 70 as a synonym either. Nor has C. obtusata, A. M. NORMAN, 1869,
pp. 256, 257, 260 and 295 been included; with regard to this find, which is presumably the same
as was the basis of G. S. BRADY’s information, 1868 a and b, the first-mentioned writer says
(p. 295): ,,A single imperfect Conchoecia, believed to belong to this species . . . .“
It is true that there are a number of small differences to be noted between the descriptions
of this species worked out by preceding writers and the information given by me above, but it
does not seem to me necessary to discuss these in any detail. Most of them are presumably
due to lack of accuracy on the part of the previous writers.
There is so far no information in the literature as to the proportion between males and
females in this species. In the material from Skager Rak investigated by me the males were in
most cases rather considerably fewer than the females. Thus in a sample from Koster there
