Turbot Bank. On the 22nd June some exploration was effected, and on 
the 23rd a steamer was engaged from Belfast, when a quantity of material 
was obtained from the Bank and the deep water adjacent. After the copious 
list published in the Report of the British Association for 1857, it would be 
needless to repeat the whole of the species obtained during the present 
season ; but in order to show the richness of the deposit, a list is here given 
of the contents of a small basketful of the shell-sand forwarded to J. Gwyn 
Jeffreys, Esq., and communicated by him as follows :—
