at 10 a.m. and noon on August Ist, 1896 (net down 15 minutes each time). 
* The total contents of the two hauls measured about 13 ¢.c., but about 
half of this quantity consisted of flocculeut matter, the other half being 
made up of cath gen 0 and Salpe. The following are the organisms 
observed :— 
Calanus finmarchicus (Gunner). 
Eucalanus crassus, Giesbrecht. 
Pseudocalanus elongatus, Boeck. 
Temora longicornis (Miiller). 
Metridia hibernica (Brady 
Robertson). 
Acartia Clausii, Giesbrecht.

Ectinosoma atlanticum

Paracalanus parvus, Claus.

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., 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. 
Pseudocalanus elongatus, Boeck, few. 
Acartia Clausit, Giesbrecht, few. 
Orthona (1) similis, Claus, few. 
FPodon intermedius, Lilljeborg, few. 
Salpa (*) vulgaris, frequent. 
(2) Arachnactis, sp., rare. 
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. of flocculent matter. The Entomostraca numbered, approxi- 
mately, about 4000. The following are the names of the organisms 
observed :— 
Calanus finmarchicus (Gunner). 
Hucalanus elongatus (Dana). 
Podon intermedius, Lilljeborg.

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., and consisted 
mostly of flocculent matter: several species of Entomostraca were. observed,
