B56 TRANSACTIONS LIVERPOOL BIOLOGICAL SOCIETY. 



Like some of the previous hauls, it contained Cupulita 

 sarsi and a large number of Calanus finmarchicus . 

 There was also one specimen of Nyctiphanes couchii. 

 The araometer record here was 27*2, and the pure 

 Atlantic water no doubt comes in here from the west 

 through the wide Sound of Barra. 



The next vertical haul further north was on 

 August 9th, from 94 fathoms, at a spot five miles east 

 of the mouth of Loch Eport in North Uist, and this 

 again showed an oceanic zoo-plankton containing a large 

 number of Calanus finmarchicus and other oceanic 

 Copepods, amongst which we found one hundred 

 specimens of Metridia lucens. The neritic Evadne 

 nordmanni also occurs in this gathering. 



We have next two hauls, one vertical and the other 

 surface, taken at the same time in the outer part of Loch 

 Seaforth, between Harris and Lewis, on August 10th. 

 The vertical haul was from 43 fathoms, and was a large 

 gathering of a phyto-planktonic character, and mainly 

 neritic. As it was the most abundant haul that we 

 obtained in the Outer Hebrides, we insert -the details 

 here, as follows : —
