 Miirz 1906 gilt dasselbe. falls nicht schon im Marz das Aiifsteigen beginnen sollte. Gegen das Auf- 

 steigen zum Zwecke der Begattung im Februar sprechen die iibrigen Untersuchungen. Es konnte 

 sich auch um das Aufsteigen unreifer Exemplare infolge besonderer hydrographischer Verhiiltnisse 

 handeln; solche finde ich aber fiir Februar 1904 niclit; es konnte sich ja auch nur um Aenderungen 

 des Wassers dicht liber dem Boden handeln, da die Tiere auf dem Boden leben." 



In the plankton tables of the ,,C o n s e i 1 permanent etc." there is no information 

 about the sex of the specimens captured and consequently there is not in C. Apstein's either 

 any information as to whether females of this species are to be foimd in the plankton or whether 

 his statements, like those of Sars, Lilljeborg and AURIVILLIUS mentioned above, are to be 

 referred to finds of males only. C. Apstein himself had evidently no opportunity of investigating 

 the material on which the plankton tables in question were based. 



The collection of s t r a c o d s in the Swedish State Museum comprises 

 partly very abundant material of Philomedes (Ph.) globosa (about a himdred samples amounting 

 to many thousand specimens; most of these specimens had been captured at the bottom, but also 

 plankton samples occur), partly representatives of four other species of this genus, viz. the Scandi- 

 navian Ph. (Ph.) LiUjehorgi and the Antarctic Ph. (Ph.) rotunda, Ph. (Ph.) Engeniae and Ph. 

 (Sdernconcha) Appellofi. This material has been subjected to a very careful investigation by nic. 



My investigations of Philomedes (Ph.) globosa gave the following results:
