The Pelagic Entomostraca Collected by the Tow-Nets. 



The Entomostraca contained in the tow-net gatherings from Loch Lochy 

 are very similar in number and kind to those from the Loch Ness 

 gatherings. The only difference worth noting is the presence in Loch 

 Lochy of Holopedium gibberurn ; and curiously, though this species 

 occurred in all the four gatherings collected on 4th August 1898 at the 

 surface and at ten fathoms, twenty fathoms, and fifty fathoms, it was not 

 observed in any gathering on the other dates mentioned in the following 

 Table of Species.
