surface, at ' Knight Errant Station No. 33,' lat. 60°3' N. long. 5°51' W. 

 at 10 a.m. and noon on August 1st, 1896 (net down 15 minutes each time). 



The total contents of the two hauls measured about 13 c.c, but about 

 half of this quantity consisted of flocculeut matter, the other half being 

 made up of Entomostraca and Salpce. The following are the organisms 

 observed : — 



Calanus finmarchicus (Gunner). Acartia Clausii, Giesbrecht. 



Eucalanus crassus, Giesbrecht. Oithona (?) similis, Glaus. 



Pseudocalanus elongatus, Boeck. Ectinosoma atlauticum (Brady and 



Temora lovgicomis (Midler). Robertson). 

 Metridia hibemica (Brady and Podon intermedins, Lilljeborg. 

 Robertson). Salpa (?) vulgaris. 



Paracalanus parvus, Glaus. 



Calanus and Pseudocalanus were scarce, Acartia was frequent, Salpa 

 was also frequent, but all the others were more or less rare. 



9, 10. These two gatherings were put together in the same bottle: 

 they consisted of the contents of two hauls with the tow-net, at 

 the surface of the water, at the same station as the last, and 

 collected on the same date, at 2 p.m. and 4 p.m. (the net being down for 

 15 minutes each haul). 



The total contents of the two hauls measured only about 5 c.c, and 

 consisted chiefly of Salpa and some flocculent matter. Entomostraca 

 were scarce, only five species being observed, of which the following are 

 the names : — 



Calanus finmarchicus (Gunner), rare. Podon intermedins, Lilljeborg, few. 

 Pseudocalanus elongatus, Boeck, few. Salpa (?) vulgaris, frequent. 

 Acartia Clausii, Giesbrecht, few*. (?) Arachnactis, sp., rare. 



Oithona (?) similis, Claus, few. Ctenophora, rare. 



11, 12. These two gatherings were put together in the same bottle: 

 they consisted of the contents of two hauls with the tow-net, at the surface 

 of the water, at the same station as the last ; they were collected at 2 p.m. 

 and 3.30 p.m. on August 2nd, 1896 (the net being down 15 minutes 

 each haul). 



The total contents of these two hauls measured about 11 c.c, including 

 about 1 c.c of flocculent matter. The Entomostraca numbered, approxi- 

 mately, about 4000. The following are the names of the organisms 

 observed : — 



Calanus finmarchicus (Gunner). Podon intermedins, Lilljeborg. 



Eucalanus elongatus (Dana). Limacina retroversa ( Fleming). 



Aetidius armatus, Brady. Sagitta. 

 Euchozta norvegica, Boeck. Tomopteris. 

 Metridia hibemica (Brady and Ctenophora. 

 Robertson). 



The formula shows the proportional numbers nearly—

13. This gathering consisted of one haul of the tow-net, at the same 

 { Knight Errant Station ' as the last, collected at the surface at 10 a.m. 

 on August 3rd, 1896 (the net being towed for 15 minutes). 



The total contents of the haul measured about 9 c.c, and consisted 

 mostly of flocculent matter : several species of Entomostraca were observed,
