Deep Space 9 - vessel arrival roster

The arrival roster at Deep Space 9 listing Capt. Priestly

Captain J. Priestly was a Starfleet officer in the 24th century. Priestly was the commander of the USS Gallico.

In 2370, Priestly was listed on the Deep Space 9 arrival roster. (DS9: "Whispers", production art)

This character was only mentioned in writing.
Captain Priestly was apparently named for Jason Priestley, star of Paramount Television's Beverly Hills, 90210. His name was not mentioned in dialogue, but was simply listed in an okudagram graphic of an arrival roster on a viewscreen. The graphic was also populated by a number of other in-jokes.
