Tellus was a Vulcan captain in the 20th century, commander of the survey ship D'Vahl.

In 1957, a Tellarite freighter relayed the distress call of a stranded Vulcan survey ship to the Vulcan High Command, who then dispatched the D'Vahl to Earth. Part way there, he contacted the team to see if they had survived.

Upon arriving at Earth, late at night to avoid the Humans seeing them, he was curious as to where the other two members of the team were. T'Mir informed him that only she and Stron had survived. They then proceeded back to Vulcan. (ENT: "Carbon Creek")
