The almost extinct family of the _Struthionidæ_, or wingless birds, of New Zealand, forms one of the most interesting features in the _fauna_ of the country. All the members of this genus are wholly different from the common types of birds. They are remarkable for short rudimentary wings, entirely unfit for flight, and for bones nearly devoid of air cells; the leg muscles are of unusual strength and thickness; the feet are powerful and long, with three toes, while the plumage is composed of light, shaggy feathers, almost resembling hair. Before its period of extinction, the largest member of this family, known by tradition to the natives as the _moa_, was the giant of the feathered tribe, the height of the several species of this bird, as computed from its remains, being as follows:--- Feet. Inches. Dinornis Giganteus 11 0 " Robustus 8 6 " Elephantopus 6 8 " Casuarinus 5 6 " Crassus 5 0 " Didiformus 4 8
