vertical plankton hauls in deep water. At the entrance 

 to Loch Fyne, off Skate Island, in 104 fathoms, we got 

 13,000 adult Calanus kelgolandicus in one haul on 

 July 18th ; and off Buidhe Island, near East Loch 

 Tarbert, in 76 fathoms, we got 10,000 of the same species 

 on July 27th, along with Euchaeta norvegica, Nyctiphanes 

 norvegica, and other interesting forms. Calanus seems to 

 be permanently present in the deep water of the west 

 coast. 



Anomalocera, on the other hand, first appears in our 

 records on March 29th, and then only in the form of 

 metanauplii (100, 170, and 30 in surface hauls off the 

 Calf Island). Then on April 1st the deep net (10 fathoms) 

 took 75 young, in their second-last stage of development. 

 The same young stages were taken again on April 4th, 5th 

 and 6th, with various nets, chiefly on the surface, and the 

 first adults on April 9th, after which both adults and 

 young continued to occur during the remainder of the 

 month. The numbers on a few dates in April are: —

May, June and July, but it must be remembered that 

 during these months gatherings were only taken once a 

 week. The species is recorded again on August 19th, and 

 continues to be represented, in small numbers, by both 

 adults and young, throughout August and September, and 

 finallv on November 8th. We have, however, noted its
