Troglyte
From Memory Alpha, the free Star Trek reference
The Troglytes were the zenite miners of the planet Ardana and were the lower social class of Ardanans. Their name comes from an abbreviation of an ancient Earth term, translating as "cave dweller".
The Troglytes had long unkempt hair and wore special visors that could be related to their harsh work environment in the mines. They lived on the planet's surface and prior to 2269, were inebriated due to the odorless gas zenite emanated in its raw form.
Although they were slow to believe the idea that a problem with the gas existed, they eventually agreed to take a supply of filter masks to counter it. With the problem solved, the Trogyltes vowed to strive with even more vigor and effectiveness in securing their rights. (TOS: "The Cloud Minders")
