. The Canadian record of science. Natural history. Geology and Fossil llora of 161 "habit of growth is that of Walchia. The species is near to W. imhrlcati of the European Permian, but sufficiently distinct to deserve a name, and I have therefore called it W. imbricatula <Fig. 2).. urn ^0^*^ Fig. 2. Walclxia iiribricatida, , Tiiaa, Prince Edward Island. Prom a drawing by Mr. Bain. It is to be observed that, in the red sandstones of Prince Edward Island, all the more delicate plants, and even twigs of coniferous trees, have completely lost their organic matter and are represented by mere impressions, stains, or casts in clay or sand, so that it is very difficult to ascertain their minute charac- ters. The general result, in so far as the subdivision of the beds is con cerned, would seem to be that the lower series is distinctly Permo-carboniferous, that its extent is considerably greater than we supposed in 1871, that there is a well-characterised overlying Trias, and that the intermediate series, whether Permian or Lower Triassic, is of somewhat difficult local definition; but that its fossils, so far as they go, lean to the Permian side. The further researches of local observers like Mr. Bain may be expected to throw new light on these points, and to enable a more exact separation to be made of the several deposits. 11.
