Planet: Bolarus IX. A Federation race of humanoids, most distinguishable in appearance by the narrow yet distinctive ridgeline running at least from over the skull from the spine to the nose and down the neck. In addition, they also have longer ears than humans and their skin tone ranges from a yellowish green tinge to a blue darker green tinge to medium blue. Though very few Bolians serve in Starfleet, they can be found in various places throughout the Federation. Natives of this bald, bluish-skinned Federation race are seen on the U.S.S. Voyager.
