The Bendriggans were a species.

On a mission for the Time Lords, the Fourth Doctor was sent to destroy a space station that held the Bendriggans' virus. However, he and Sarah Jane were accused of murdering a messenger and sentenced to death by Admiral Cosmicon, the Bendriggan commander. The Doctor proved his innocence by sending a message in Time Lord logic to a Bendriggan code expert. But winning their trust was short-lived when many Bendriggans became infected. After watching the Admiral die, the Doctor set the Bendriggan flagship on a collision course with the space station, destroying them both and saving the remainder of the Bendriggan race.
