Narrative:

On a flight from wrangel, alaska, to ketchican, alaska, noted a vibration coming from the nose area of the aircraft. Wrote up the problem in ketchican. Had maintenance look at the aircraft. They could find no problems and signed the aircraft off as 'could not duplicate.' departed ketchican for seattle, wa. On descent into seattle descending through 18000 ft noted the vibration again. Called our maintenance people and had maintenance meet the aircraft and described in detail what we observed regarding the vibration. Maintenance towed the aircraft to the hangar for repairs. Between talking to maintenance, saying good-bye to my passenger and flight attendants, and clearing out of the cockpit I neglected to make another write-up in the logbook regarding the vibration problem.
