Dear Deepak,

No this is not C. hamiltoni. It is a species which is characterised by its orange background colour and black lines edged in white. At present I am calling it 'Chromodoris cf colemani' but there are probably two or even three 'species' clustered together under that name. Until we get more material for comparison I am not sure if these are all varieties of one new species or perhaps variations of existing species.

Best wishes,
Bill Rudman
