A security guard on the Enterprise in the second and third seasons of the original series, played by Roger Holloway and seen escorting prisoners, visitors and landing parties.
Lemli is a recurring security officer aboard the Enterprise, played by background performer Roger Holloway from the second season onwards. He first appears in The Changeling and is seen in more than a dozen episodes.
His work is that of the typical ship's guard: standing watch in corridors, escorting guests and prisoners and joining landing parties. He can be seen in The Trouble with Tribbles, The Enterprise Incident, Day of the Dove and Let That Be Your Last Battlefield.
He is last seen in Turnabout Intruder, the final episode of the series. The name is said to be a nod to William Shatner's daughters Leslie, Melanie and Lisabeth.
