Cyrano Jones was an intergalactic trader and, to Captain Kirk, a general nuisance who lived during the mid-23rd century. Among his wares, Jones pawned articles such as Spican flame gems, Antarean glow water and tribbles.
In 2268, Jones was present on the Federation Deep Space Station K-7 during the Klingon plot to control Sherman's Planet, having arrived on the station aboard his merchant starship, the Spacematic. He was responsible for the station's infestation with tribbles, which he was sentenced to clean up or face a twenty-year prison sentence for transporting a dangerous lifeform off its native planet. His sentence was expected to take 17.9 years, which Kirk cuttingly suggested can best be considered "job security" for the massiveness of the task.
