Excerpt from Figures and Descriptions of Canadian Organic Remains, Vol. 3
One of the subjects comprehended in the recommendation of the Select Committee appointed by the House of Assembly, on the Geological Survey, in 1854, was the publication Of figures and descriptions illustrative of such new organic' forms 'as might be Obtained in the progress of the investigation. In compliance with this recommendation, it was determined that the publication should be made in parts or decades, after the mode adopted by the Geological Survey of the United Kingdom, each part to consist of about ten plates, with appropriate descriptive text, and to comprehend one or more genera or groups of allied fossils, or the description of several species, for the illustration of some special point in geology.
The first part or decade was confided for description, in 1855, to Mr. J. W. Salter, one of the Palaeontologists of the Geological Survey of the United Kingdom. This comprehends different genera and species from one locality. Of these, several are new, while Others are more perfect forms of species already partially described; and the general object is to exhibit a commingling of forms here tofore supposed to belong to distinct epochs. The plates of this decade are the work of Mr. W. Sowerby, from drawings by Mr. R. C. Bone. The engravings are on steel; nine of the plates are finished, and it is expected the tenth will be completed in a short time.

Paperback. Zustand: New. Print on Demand. This book contains detailed descriptions of new species of such extinct marine animals as cystoids and starfish that once flourished on the ocean floor during the Silurian era. The author begins by introducing the reader to the geological context and evolutionary history of this distinctive group of organisms whose skeletal remains consist of a protective dermal or external skeleton adorned with ornamentations. This protective 'coat of mail' was composed of thin calcareous plates that shielded them from predators and provided stability during their sedentary existence. Additionally, the book examines the fossil remains of their exoskeletons and explores their significance in paleontological studies. The author traces the evolution of these creatures from their initial appearance in the fossil record, through their proliferation and diversification during the Silurian era, to their extinction before the Carboniferous period. The author's research provides unparalleled insights into the anatomy and development of these fascinating extinct species, shedding light on their evolutionary relationships and paleoecological significance.
