Extract

Mr. H. M. Ami, F.G.S., of the Geological Survey of Canada, who has devoted special attention to the fauna of the Utica Shale in the neighbourhood of Ottawa, lately sent me for examination several fragments of slabs of this rock containing some peculiar sponge remains, which seem to me to be worthy of notice, although, from their mode of preservation, no decisive determination as to the character of the sponge.to which they belong can be arrived at.
