The notes by Professor Grenville A. J. Cole & Mr. T. Hallissy on the Wexford Gravels, and those by Dr. F. Cowper Reed on the Manxland shells in the Strickland Collection at the Sedgwick Museum, Cambridge, published in last year's Geological Magazine, will be welcomed by geologists as drawing attention to an interesting but too long neglected subject. The principal object of this paper is to point out the faunal relations of the deposits in question to each other, and wherein they differ from those of the neighbourhood which are usually grouped with them, including the high-level shelly drifts of Moel Tryfaen, Macclesfield, Gloppa, and the Wicklow Mountains, the limestone drifts and shelly clays of Ireland from Ballybrack Bay to Glenarm, and the stony or boulder clays of Cheshire and Lancashire.
