ORDER IV. — Batrachia. 
This order is divided by Mr. Gray (see Synopsis at the end of 
onr ninth volume) into two very natural orders or families, accord- 
ing as they do or do not undergo metamorphosis. Cuvier has indi- 
cated the same division, and has then proceeded to subdivide them 
as follows : —
