In the October suehee of the Annals and Magazine of Natural His-

several eggs and apparently to different Sects of the Moa; the linear 
markings are variously disposed in different specimens. Mr. Walter 
Mantell’s collection of bones amounts from seven hundred to eight hun-

the mandibles which have not been previously obihihed. These bones 
will doubtless furnish some interesting additions to our knowledge of
