9. Java. 

 The Java group, including Floris and Timor, have been partially explored 

 from the head-quarters of the Dutch settlement at Eatavia. The land and 

 fresh-water shells are nearly all peculiar, a few only being common to the 

 Philippines and N. Australia; they have been described and figured by M. 

 Albert Moussoa (Svo. Zu/ich, 1849, 22 plates). 



10. Borneo. 

 The land shells of this great island are almost unknown, and the only 

 reason for mentioning it separately is the doubt whether it should be con- 

 sidered part of the Javanese Province, or associated with the Moluccas and 

 Philippines.

The freshwater bivalves are Glaucomya rostralis, Corbicula tumida and 

 Cyrena triangularis. Pholas rivicola was found burrowing in floating logs 

 used as landing places, 12 miles from the sea, up the Pantai river. The 

 mangrove swamps abound with Cerithidiura, Terebralia Telescopium, Potami- 

 des palustris and Quoyia ; Auricula Midae and Polydonta scarabseus inhabit 

 the damp woods. 



11. Papua and New Irela.nu. 



The landshells of New Guinea are nearly all distinct from those of the 

 Philippines and Moluccas and include some related to the Polynesian types. 

 The Louisiade Islands to the south-east and New Ireland on the North of 

 New Guinea are included with it.
