I can see on the bottom of this document that for vessel it's written Allan Line.
S/S Parisian Allan Line Liverpool 1886-03-25 Halifax 1886-04-04 Londonderry - Portland
The most likely vessel would be this one I guess. However i found a old newspaper article regarding a passenger from Trondheim that also was on this trip. He had ticket with Cunard Line and was stranded in Liverpool for a long period awaiting available vessel with this company. He was still in Liverpool in the end of March.
