INTRODUCTION.
„It seems to me most desirable that minute,
and even apparently trivial, features should
be given in the descriptions of species“.
C Stewart*
This work is nol
a monograph; the
reasons jor this.
In the present work there has been collected under the title of „Studies o n marine
Ostracod s“, Part I a part of the results that have proceeded from the investigations that I
have carried out during the last few years on the marine representatives of the Ostracods,
a group of Crustacea which is in many respects particularly interesting, botli to the zoologist
and the geologist.
One criticism that may possibly be made against this work is that although it is rather
voluminous, it has not the form of a monograph; a number of the many problems presented
by the marine Ostracods have been left quite untouched, and my efforts have been
con-centrated on others — some of them verv heterogeneous in their nature.
I must readily admit the justice of this criticism. The type of the work seems anything
but satisfactory to myself. It is, as the title itself shows, a conglomération; some of its integral
parts are quite independent of each other.
Although the marine Ostracods have been treated by a number of investigators
in a comparatively large number of works, it may be said not without justification that, on
account of the uneertainty and superficiality that characterizes the great majority of these
works, they constitute a subject that in many respects is almost entirely unknown. Under
these circumstances it would of course have been most convenient to have directed these studies
on a smaller systematic unit, for instance one family or even one genus, and to have submitted
this to a fundamental and comprehensive examination or to have examined the Ostracod
group as a whole from the point of view of a limited problem. In this way a result that was
more favourable in many respects might certainly have been obtained and at the same time
the treatise might have been more homogeneous from a structural point of view, a real unit.
As a matter of faet this was the direction I intended at first to take. My first studies
were concentrated on the Cypridinids and H aloe y p r i d s.
