DISTRIBUTION. 
Geographical. Recent. 
Lydekker (147) proposes the following zoogeograpliical divisions : — 
l . Notogoeic Realm, with Australian, Polynesian, Hawaiian, and Austro- 
Malayan Regions ; ii. Neogaeic Realm, with the Neotropical Region ; 
m. Arctogaeic Realm, with Malagasy, Ethiopian, Oriental, Holaretic, and 
Sonoran Regions. Cope (58) suggests an amended scheme, viz. : — i. 
Australian Realm ; II. Neotropical Realm tii. Ethiopian Realm ; 
tv. Arctogean Realm, with Indian, Holaretic, and Medicolumbian 
[Sonoran] Regions. Matsciiie (159) defines a Mediterranean Region. 
Sclater (237) continues his memoir.
