Mr. Seebohm then offers an " alternative scheme," founded principally 

 on the condition of the young when hatched. This character has 

 before been considered of value by naturalists, and the late Professor 

 Sundevall made use of it in his classification ; but it is liable to excep-

 diagnoses. In this " alternative scheme " the linear sequence of the 

 Orders is slightly altered and only five Subclasses are recognized. The 

 result is as follows : —
