Need help identifying anything about uniform

[smacks0311USMC]

Can anyone tell me anything about this man's uniform, rank, medals, perhaps even an approximate year?

(G-G-Grandfather)

Thank you

My best guess is British, Victorian Era, late 19th century.  Likely an officer.  I see a load of campaign medals and what looks like the badge of the Order of the Garter.
