The Banded white pattern mutation occurred in 1957 in the USA. The Banded pattern turns the belly to pure white and places a band of white across the middle of the back. The band across the back may be incomplete resulting in a line of colour breaking through the centre of the band or there may be coloured spots within the white band across the back.
The Banded white pattern can be combined with any colour to produce a Banded variety of that colour eg Golden Banded, Cinnamon Banded, etc.
For showing the band should take up the middle third of the body with no coloured spots or breaks in the band. The borders between colour and band should be straight as possible.
