It may not be amiss to give here an outline of the genera composing 
the Family of Struthionide, seeing they are but few. Each genus contains 
but a single species. In the present state of our knowledge the group may 
be thus arranged :—

1. Genus Struthio, Linn. (Type of the group.) Ostrich of South Africa: 
possessing two toes. ;
