One author, Riley Martin (1946-2015), in his book "the coming of Tan" mentions a non-human race called the Biiaviians. They are inhabitants of a planet called, Biaveh, 450 light years from Earth in the Taurus constellation. Together with six other races, they would have a mothership around Saturn.

Riley claimed to have been in touch with Tan, one of these Biiaviians for approximately 50 years.

In his book, he describes them as follows: The male was about four feet tall, and the female was a few inches shorter. In actual appearance, male and female differed just slightly in features. The heads were noticeably larger than normal in proportion to the body. The eyes were large, unblinking ovals. The male's eyes were a light to deep gold color, while the female's eyes were blue. The shades of their eyes tended to change depths, depending upon the light and perhaps the emotion.
Their arms were long, the fingertips reaching almost to their knees. Their feet looked flat and kind of splayed. Their hands were long and delicate and had only three fingers and a thumb. The forefinger was longer than the middle finger. They had no outward ear flaps, but tiny holes where the ears should be. The nose had no cartilage and was almost flat against the profile. The mouth was thin-lipped and looked like a slit on the face. The teeth were tiny and uniform, like baby teeth. The chins were sharp and receding and gave the face an egg-like shape.
The female's skin tone was a gray white, and the male's complexion was yellowish brown or golden. The skin colors also changed at times, not in basic color but in subtle tones. They did not look like dangerous monsters, but I could not call them cute either. They did not articulate with their mouths but communicated via telepathy.

Riley claimsed the Biiaviians got involved in Earth's Galactic history when 70 million years ago, their war with the Targ spread to our Solar System. It was then that they decided to wipe out all dinosaur life forms of Targ descent on Earth.

No other authors mention the Biiaviians. Many researchers question his credibility.
