The group has submarine connexion, under relatively shallow sea, with the Timorlaut group to the south-west and the chain of islands extending north-west towards Ceram; deep water separates it on the east from the Aru Islands and on the west from the inner islands of the Banda Sea.
And 12 5° 45'- 1 35° E.), including the island-belt which surrounds the sea on the north, east and south; and is divided for administrative purposes into nine districts (afdeelingen): 1) Amboyna, the island of that name; (2) Saparua, with Oma and Nusa Laut; (3) Kajeli (Eastern Buru); (4) Masareti (Western Buru); (5) Kairatu (Western Ceram); (6) Wahai (the northern part of Mid-Ceram); (7) Amahai (the southern part of Mid-Ceram); (8) the Banda Isles, with East Ceram, Ceram Laut and Gorom; (9) the islands of Aru, Kei, Timor Laut or Tenimber, and the south-western islands.

The great chain of volcanoes which runs through Sumatra and Java is continued eastwards into the Moluccas, and terminates in a hooklike curve which passes through the Damar Islands to the Banda group. Outside this hook lies a concentric arc of non-volcanic islands, including Tenimber, the Lesser Kei Islands, Ceram and Buru; and beyond is still a third concentric arc extending from Taliabu to the Greater Kei Islands.
