The Lymax were a species that came from the same galaxy as the Gorn. They were discovered by the Enterprise crew when they went through the rip in space made by the Helios Machine. Their biological makeup was not suited for the planet they were discovered on, and were probably driven there by the Gorn. Some were enslaved, experimented on, and forced to fight gladiator style, with a crossbow as their choice of weapon. (TOS video game: Star Trek)

The Lymax had short, skinny legs and long arms that drop to the ground. They also had stubby tails, pinkish skin, long ears, and facial appendages of unknown use. They had multiple religious iconography, with many statues of their Gods and other religious artifacts. (TOS video game: Star Trek)
