If these gravels are of the same age as the one in Balbriggan Bay, the 
conditions under which they were accumulated were very different, as in 
them most of the shells are perfect and in situ; while at Balbriggan they 
are all broken and have drifted into their present position. 
Waterford Haven. 
Brief reference may be made to the estuarine flats in Tramore Bay, 
County Waterford, which fall within the human epoch, and abound in the 
shells of the common cockle. These flats hdve an elevation of 8 to 10 
feet above high water, the shell bands ranging from 2 to 12 inches in 
thickness. In one of these Major Austen’ saw a human skeleton evi- 
dently contemporaneous, as the shells were lying both above and below 
it. From the notes kindly sent me by Mr. E. Garnett, of Newtown, these 
beds must have been still more elevated, as they underlie at one extremity 
a thick bed of dark turf-like mould, containing many stumps and roots, 
mostly of birch and oak trees. The late Professor EK. T. Hardman told 
me that he had seen other shells besides the cockle, such as Aporrhais, 
Littorina, Turritella, &c., but had not time to examine the bed thoroughly. 
They must be rare, as Mr. Garnett writes that he could only find the one 
Species, 
; A deposit of the same age as the above may be that known as Clay Castle, 
Youghal, an eminence facing the sea, built up of a gravelly sandy clay, 
with shells of the ordinary type such as the ordinary whelk, limpet, 
mussel, and cockle, with a few others. 
Portrush, Co. Antrim. 
The deposit here consists—or rather did so, since the building of a 
road round the small bay in which it occurred has blotted it out of sight— 
of a bed of sand formed in and about the hollows of the rocks some ten 
feet above high-water. Originally discovered by the late Mr. James 
Smith, of Jordanhill, its fossils were referred to in a list given in Port-
