ON THE MANURE GRAVELS OF WEXFORD. 417 
some other similar deposits have still to be examined. So far as yet 
known, although microzoa are plentiful, shells and other organisms are 
scarce in comparison with the number of localities. Species marked f+ 
occur mostly in unequal proportions, both at Magheramorne and Belfast ; 
those marked * at Magheramorne only, the remainder only at Belfast. 
The Magheramorne list, and all those in italics, are on my own responsi- 
bility, and I have been able to verify most of the remainder through the 
courtesy of Mr. Stewart.
