The raised beach between Ballygally and Glenarm is also 
being rapidly destroyed for the same purpose. 
The two deposits I have just mentioned, although differ- 
ing slightly in their moUuscan fauna, both from their posi- 
tion above the present sea level and the general facies of the 
shells tlierein, may, I think, be referred to the same period 
of depression of the land. The shells, although mostly of 
species now found living in the adjoining sea, present a 
northern or boreal a,spect ; some indeed are typical of glacial 
beds. 
In the naming of them I have had the kind assistance of 
Mr. K. D. Darbishire, RG.S. 
My list must not be considered a complete one, as it con- 
tains only the names of those species T have myself obtained 
and of which I exhibit specimens; but it will give an idea 
of the richness and character of the deposit. 
The raised beach at tlie Curran of Larne is an extensive 
deposit through which the railway and road to the harbour 
are cut, and is from 10 to 20 feet above high water mark. 
It consists of stratified sand and gravel ; the stratum of 
sand 2 to 3 feet thick forms the lower part, while the 
remainder is made up of firmly compacted gravel and sand ; 
the stones, some of which are of considerable size, are prin- 
cipally of flint, hard chalk, trap, and lias ; rolled specimens 
of Gryphoea incurva are also met with. 
In the sandy layer near the base, I found Tapes pullastra 
and numerous specimens of the young of Lucina borealis^ 
with both valves in apposition, showing that they had lived 
and died on the spot. , 
Most of the shells are blanched and fragile ; some of them 
falling into powder in the act of extraction. 
To shew the chemical decomposition going on, two very 
curious examples were exhibited of a Littoriua and Natica, 
in which the outer layer of the shells has been decomposed 
leaving only the thin inner ones as casts. Some of the 
smaller shells are often preserved from injury by being 
enclosed in the mouth of some of the larger species of uni- 
valves.
