306 Part I1I.—Fifteenth Annual Repom S. 
The number of Entomostraca was, approximately, about 4000, and the 
proportions of the species, the one to the other, nearly as in the formula— 
Calanus, Pseudocalanus, Temora, Acartia, Oithona, Podon.

There were two specimens of Hucheta and one of Parathenisto. Besides 
the usual Diatomacea, Infusoria, and Radiolaria, there were a few speci- 
mens of Gloligerina in this gathering. 
4. This gathering consisted of one haul of the tow-net, collected at the 
surface, at ‘Jackal Station No. XIII.,’ lat. 61°1’ N. long. 3°12’ W,, on 
July 31st, 1896, at 10 a.m. (net down 15 minutes). 
The total contents of this haul measured about 10°5 c.c., including about 
‘D c.c. of flocculent matter. The following organisms were observed in this 
gathering :— 
Calanus finmarchicus (Gunner). Otthona (*) similis, Claus. 
Pseudocalanus elongatus, Boeck. Podon intermedius, Lilljeborg. 
Temora longicornis (Miller). Parathemisto gracilipes, Norman. 
Acartia Clausti, Giesbrecht. Limacina retroversa (Fleming). 
The number of the Entomostraca was about 4500, and the proportional 
numbers of the species nearly as in the last gathering. Limacina was 
very rare. 
5. This gathering consisted of one haul of the tow-net, collected at the 
same station, and on the same date as the last, at 11.30 a.m. (net down 
15 minutes). 
The total contents of this haul measured about 11:5 ¢.c., including 
about 0°5 c.c. of flocculent matter. The following were the organisms 
observed :— 
Calanus finmarchicus (Gunner). Acartia Clauusii, Giesbrecht. 
Pseudocalanus elongatus, Boeck. Oithona (2) stmilis, Claus. 
Temora longicornis (Miller). Podon intermedius, Lilljeborg. 
Centropages typicus, Kroyer. Parathemisto (?) gracilipes, Norman. 
The total number of Entomostraca was about 5000, the proportional 
numbers of the species being somewhat similar to those of previous 
gatherings. 
6. This gathering consisted of one haul of the tow-net, collected at the 
surface, at the same station as Nos. 4 and 5, and at the same date, at 
2 p.m. (net down 15 minutes). | 
The total contents of this haul measured about 12°5 c.c., 1°5 cc. of 
which consisted of flocculent matter. The ge lowing are the organisms 
observed in this gathering :— | 
Calanus finmarchicus (Gunner). Podon intermedius, Lilljeborg. 
Pseudocalanus elongatus, Boeck. Evadne Nordmanni, Loven. 
Temora longicornis (Miller). Parathemisto (2) gracilipes, Norman. 
Acartia Clausii, Giesbrecht. Limacina retroversa (Fleming). 
Oithona (*%) similis, Claus. Sagitta. 
Globigerina. 
The total number of Entomostraca and the proportional numbers of the 
different species were similar to the last.

7, 8. These two small gatherings were put together in the same bottle : 
they consisted of the contents of two hauls of the tow-net, collected q the
