The Pelagic Entomostraca Collected by the Tow-Nets. 



The Entomostraca observed in the various tow-net gatherings comprise 

 altogether about twelve species, but a few of them are exceedingly rare. 

 The most numerous forms were two species of Diaptomus — (D. Mrcus, 

 G. S. Brady,* and D. gracilis, G. O. Sars) ; and Bosmina longispina, 

 Leydig. The next in order of frequency were Daphnia galeata, G. O. 

 Sars ; Bythotreplies longimanus, Leydig ; and Leptodora hyalina, 

 Lilljeborg. Cyclops strenuus, Fischer, was also occasionally more or less 

 frequent. The following Table will show approximately the relative 

 frequency of the different species and their seasonal distribution. The 

 gatherings represented in this- Table were collected on six different dates, 

 viz., on 6th August, 28th October, and 6th and 7th December 1897, and 

 on 25th January, 3rd August, and 7th October 1898. The following 

 abbreviations are used in the Table : — ab — abundant ; c — common \ fr — 

 frequent ; and r — rare. "0 " also signifies the absence of any species. 

 * See Notes on this and other species at p. 188.
