Abstract
THE recent discovery of a fine suite of Late-glacial strata near Ballyhalbert on the north-eastern Irish coast in an accessible position has allowed a careful study to be made of the different layers for plant and animal macrofossils. Particularly interesting has been the recovery of numerous characteristic telsons of the freshwater notostracan Lepidurus arcticus, a species which was reported recently by Mitchell1 from Late-glacial levels at Ballaugh in the Isle of Man, at Neasham, Co. Durham, and at Mapastown, Co. Louth. Records from these Late-glacial contexts are significant since the species is not known in the present fauna of the British Isles. Its modern distribution is circumpolar, between 65° and 80° N.
