Part III. — Fifteenth Annual Report 



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 Euchoeta and one of Parathemisto. Besides 

 the usual Diatomacea, Infusoria, and Radiolaria, there were a few speci- 

 mens of Globigerina 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 

 •5 c.c. of flocculent matter. The following organisms were observed in this 

 gathering : — 



Calanus finmarchicus (Gunner). Oithona (?) similis, Claus. 



Pseudocalanus elongatus, Boeck. Podon intermedius, Lilljeborg. 



Temora longicornis (Miiller). Parathemisto gracilipes, Norman. 



Acartia Clausii, Giesbrecht. Limacina retrowrsa (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.c, including 

 about 0*5 c.c. of flocculent matter. The following were the organisms 

 observed : — 



Calanus finmarchicus (Gunner). Acartia Clausii, Giesbrecht. 



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



Temora longicornis (Miiller). 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 c.c. of 

 which consisted of flocculent matter. The following are the organisms 

 observed in this gathering : — 



Calanus finmarchicus (Gunner). Podon intermedius, Lilljeborg. 



Pseudocalanus elongatus, Boeck. Evadne Nordmanni, Loven. 



Temora longicornis (Miiller). Parathemisto (?) 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 at the
