 well-authenticated specimens. They are ar- 

 ranged in the following divisions : 



1. Uniform white, without spots. Chapter iv. 



2. White, spotted with red, brown, or black. Chapter vi. 



3. Spotted, on a light ground. Chapter viii. 



4. Uniform blue or green, without spots. Chapter x. 



5. Blue or green, spotted. Chapter xii. 



6. Ground various, marked with spots and irregular lines. 



Chapter xiv. 



7. Ground various, mottled with green or brown. 



Chapter xvi. 



8. Various, or not easily reduced to any of the above 



heads. Chapter xvii.
