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

 station, and on the same date, as the last : it was a surface gathering, and 

 was collected at 6 p.m. (the net being towed for 15 minutes). 



The contents of this gathering measured about 7*5 c.c, and contained a 

 considerable number of Salpcs. Though several species of Entomostraca 

 were observed, individuals were few in number. Acartia Clausii was 

 more frequent than any of the others. The following are the names of 

 the species observed : — 



Eucalanus elongatus (Dana) one. 

 Paracalanus parvus (Claus), one. 

 Pseudocalanus elongatus, ¥>OQ<ik, three. 

 Metridia Mbernica (Brady and 



Robertson), several. 

 Scolocithrix abyssalis, Giesbrecht, 



one or two. 



Euchozta uorvegica, Boeek, five or six. 

 Acartia Clausii, Giesbrecht, frequent.

 Salpa (?) vulgaris, frequent. 

 Diphys (?) campanulifera, rare. 

 Ctenophora, rare. 



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

 station, and on the same date, as Nos. 22 and 23 : like the others it was 

 a surface gathering, and was collected at 8 p.m. (the net being towed 15 

 minutes). 



This gathering, which consisted chiefly of Ctenophora and Salpa, 

 measured about 7*5 c.c. Entomostraca were comparatively few in number.

frequent. 

 Eucalanus elongatus (Dana), one. 

 Paracalanus parvus (Claus), one or 



two. 



Pseudocalanus elongatus, Boeck, rare. 

 Temora longicomis (Muller), one. 



Metridia Mbernica (Brady and Robert- 

 son), two. 



Acartia Clausii, Giesbrecht, frequent. 



Oithona (?) similis, Claus, few. 



Podon intermedins, Lilljeborg, frequent. 



Evadne Nordmanni, Loven, rare. 



Sergestes (?) atlanticus, M. Edw., one
