Ma7'ine Accumidatioiis in Largo Bay^ and Fortrush. 295 



his synonymy, somewhat complicated, brought into harmony 

 with modern standards. As in Largo Bay,^ all the species 

 are still living somewhere in British waters. Land shells 

 are not uncommon, but are more incorporated in the body 

 of the main mass than is the case with the Largo beds, 

 where they occur mostly in the higher portions of the 

 deposit. Such interlopers are by no means uncommon, as I 

 have collected them in the very marine quiescent beds of 

 the Older and Newer Eed Crags of East Anglia, the Quater- 

 nary residue at Selsey in Sussex, and the drifts on the east 

 coast of Ireland and elsewhere.

1 It is likely that the land shells of Largo Bay are more recent than the 

 marine fauna with which they arc intermixed yet.
