12. CHAPTER X.The phylum or sub-kingdom Mollusca is a group of soft-bodied animals (mollis, soft), which, although having no external skeleton, usually possess the protective covering of a sh...
13. CHAPTER XI.The above-named fossil groups are included by zoologists in the sub-kingdom Arthropoda ("joint-footed animals"). The Arthropods possess a body and limbs composed of a number of...
