308 Part II1.—Fifteenth Annual Report 
but individuals were few or rare. Acartia Clausit was of more frequent 
occurrence than any of the others. 
The following are the species that have been observed :— 
Calanus finmarchicus (Gunner), rare. Acartia Clausit, Giesbrecht, frequent. 
Pseudocalanus elongatus, Boeck, one. Hvadne 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 I| ¢.c. of flocculent 
matter. 
Calanus finmarchicus (Gunner), few. Acartia Clausii, Giesbrecht, frequent. 
Pseudocalanus elongatus, Boeck,rare. Oithona (2) similis, Claus, rare. 
Centropages typicus, Kroyer, one. Podon intermedius, Lilljeborg, rare. 
Temora longicornis (Miller), rare. Fvadne Nordmanni, Lovén, rare. 
Globigerina. 
* (2) 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. of which consisted 
of flocculent matter, the remaining 15 ¢.c. being mostly Copepoda. The 
number of Copepods in the gathering would be approximately about 5000, 
the greater part consisting of Calanus jinmarchicus. Other species (the 
names of which are given below) were rare :— 
Calanus finmarchicus (Gunner). EHucheta norvegicus, Boeck. 
Paracalanus parvus (Claus). Acartia Clausii, Giesbrecht. 
Temora longicornis (Miller). Otthona (?) 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 jinmarchicus 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. Otthona (?) similis, Claus. 
Metridin hibernica (Brady and Podon intermedius, 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, and on the same date, as 
Nos. 15 and 16: it was collected at 8 to 12 oat below the surface of the 
water, at 4 p.m. (the net, in this experiment, was only towed for 10 
minutes).
