Modiola glandula.—A single valve of this pretty lttle shell has been found at Logan's farm. It now inhabits deep water in the Gulf of St. Lawrence. I may also mention that I have found perfect specimens of Modiolaria discors both at Logan's farm and Beauport, which quite confirm Dr. Gould's identification of my fragment of last year with that species.

Fusus (Clavatula) turricula.—Specimens of this shell have been found by Mr. R. Ramsay at the Brick-yards at the Tanneries. It occurs extensively in the North Atlantic, and fossil in the British Crag. Rissoa.—Since the publication of my last paper, Mr. Bell of the Geological Survey, has shewn to me in that collection a Rissoa with five distinct revolving bands, separated by a flattish space from the suture. On comparison of this shell with my specimens referred last year to R. minuta, I am inclined to think that they are the same, but that the latter were worn, so as to present a smooth surface. It is not unlike R. obsoleta of Wood's Crag Mollusca. I have another little shell which closely resembles Alvania ascaris of the same author, but it is too incomplete for its certain identification. Spirorbis spirillum.—This common species is found of small size, attached to pebbles, at Beauport. V. General Remarks. In so far as general conclusions in Geology are concerned, the observations of the past year do not in any way conflict with the conclusions stated in my former paper. The arrangement of the deposits at Logan's farm and Beauport, confirms the subdivision which I have attempted to establish, of an underlying non-fossiliferous boulder clay, a deep-water bed of clay or sand (the Leda clay of Montreal), and overlying shallow- water sands and gravels, the Saxicava sand of my former paper. This arrangement shows a gradual upheaval of the land fro
