Rasiinian
The Rasiinians were a spacefaring humanoid species characterized by wrinkled blue skin and a bony exoskeleton covering their face.

In 2372, Ambassador Runepp traveled to Deep Space 9 aboard a Bajoran transport. The mysterious Onaya also came to the station aboard the same vessel. ()

The Borg had encountered and assimilated Rasiinians prior to 2373, as indicated by the image of one which later appeared during one of Seven of Nine's guilt-induced hallucinations. ()

Background information 

The Rasiinian in "The Muse" was played by John Paul Lona. He won a guest spot on DS9 for designing the makeup of the Rasiinian species in the Playmates Toys' "Design-an-Alien" contest. 

According to Lona's winning entry, he described the Rasiinian as having "a boney exo-skeleton which covers his soft, wrinkled skin. His glowing eyes often give away his mood, both varying in intensity and color." ()

Two other aliens have been shown with bone plating on the face; they are an inhabitant of Nimbus III and an inhabitant of or visitor to DS9.
