Can we identify this officer?

I apologise for the size of this image. It is from a group photo of men believed to be of the 22nd Northumberland Fusiliers and is marked "somewhere in France 1917". It is from a collection associated with a Corporal of the battalion who died in June 1917; we can not tell whether the man is on the photo but if so it would date it to the first half of the year.

Question is - can anyone identify the officer? The group is about Platoon size and he is the only officer present.
