308 Part III. — Fifteenth Annual Report 



but individuals were few or rare. Acartia Clausii was of more frequent 

 occurrence than any of the others. 



The following are the species that have been observed : — 



Calanus finmarchicus (Qwm\e,r),vaxe. Acartia Clausii, Giesbrecht, frequent. 



Pseudocalanus elongatus, Boeck, one. Evadne Nordmanni, Loven, few. 



Paracalanus parvus (Claus), two. Ctenophora, frequent. 



Centropages typicus, Kroyer, one. (?) Arachnactis. 



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

 station, and on the same date, as No. 13 : it was collected at the surface 

 at 2 p.m. (the net being towed for 15 minutes). 



This gathering only measured about 5 c.c, including 1 c.c. of flocculent 

 matter. 



Calanus finmarchicus (Gunner), few. Acartia Clausii, Giesbrecht, frequent. 

 Pseudocalanus elongatus , Boeck, rare. Oithona (?) similis, Claus, rare. 

 Centropages typicus, Kroyer, one. Podon intermedins, Lilljeborg, rare. 



Temora longicomis (Midler), rare. Evadne Nordmanni, Loven, rare. 



Globigerina. 

 • (?) Arachnactis. 



There were also a few Ctenophora and larval Crustacea, as well as one 

 or two young Gasteropod molluscs. 



15. This gathering consisted of one haul with the tow-net at ' Jackal 

 Station No. XIV.,' lat. 61°20'N. long. 4°22'W., taken at 11 a.m. on the 

 4th of August 1896, at the surface of the water (the net being towed for 

 15 minutes). 



The gathering measured about 16*5 c.c, 1*5 c.c. of which consisted 

 of flocculent matter, the remaining 15 c.c. being mostly Copepoda. The 

 number of Copepods in the gathering would be approximately about 5000, 

 the greater part consisting of Calanus finmarchicus. Other species (the 

 names of which are given below) were rare : — 



Calanus finmarchicus (Gunner). Euchazta norvegicus, Boeck. 



Paracalanus parvus (Claus). Acartia Clausii, Giesbrecht. 



Temora longicomis (Miiller). Oithona (?) similis, Claus. 



Globigerina, rare. 



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

 station as No. 15 : it was collected at the surface at 2 p.m. on the 4th 

 August (the net being towed for 15 minutes). 



This was comparatively a small gathering : it measured about 5 c.c, 

 including 2*5 of flocculent matter. The number of Copepoda in the 

 gathering was about 1500. Calanus finmarchicus was more common 

 than any of the others, as shown by the formula — 



Calanus, Pseudocalanus, Acartia, Oithona, Podon.

Names of the species : — 



Calanus finmarchicus (Gunner). Acartia Clausii, Giesbrecht. 



Pseudocalanus elongatus, Boeck. Oithona (?) similis, Claus. 



Metridia hibernica (Brady and Podon intermedins, Lilljeborg. 

 Robertson), two. Evadne Nordmanni, Loven, one. 



17. This gathering, which was contained in two bottles, consisted of 

 one haul with the tow-net at the same station, aud on the same date, as 

 Nos. 15 and 16 : it was collected at 8 to 12 feet below the surface of the 

 water, at 4 p.m. (the net, in this experiment, was only towed for 10 

 minutes).
