Okay, I've got a few choices here for names.

Brief explanation:

Issa is the God of the Nyissans and of snakes in the Belgarid/Mallorean series. Essa is a norse rune. It would probably be just difference in the way it's pronouced.

Nyoka is african for snake.

Pulsar. I have a cat named Nebula due to the fact that that she is a blue cream tortishell tabby. Pulsar is an astrological term.

Raju was the lamia's mate in one of the Anita Blake novels.

Other suggestions can also be posted, if you didn't post when I first got the snake. Please vote
