West of the line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origin is present. Wallace noticed this clear division during his travels through the East Indies in the 19th century. The line runs through Indonesia, between Borneo and Sulawesi (Celebes), and through the
Brünig-Napf-Reuss line the marches between Burgundy and Alemannia. Brünig-Napf-Reuss line The Brünig-Napf-Reuss line forms a geographical boundary in traditional Swiss culture (""). Running from the Brünig Pass along the Napf region to the Reuss (which joins the Aare at Brugg), it partly separates western (Bernese German) and eastern (Zurich German) varieties of High Alemannic, although some places east of the line belong to the western dialect group (Schwyz, Zug). The line runs across the cantons of Lucerne and Aargau.
