Zoological Classification - A Handy Book of Reference With Tables of the Subkingdoms, Classes, Orders, of the Animal Kingdom, Their Characters and Lists of the Families and Principal Genera #247100

Out of the genera of the animal kingdom I have selected those which are the best known or are the most representative. The genera of the Protozoa, Coelenterata, and Echinodermata are largely in excess of the other subkingdoms on account of the interest of recent investigations. The class of Insects is least re presented in proportion, the Coleoptera especially having less than an eighth of their number.
