There's an artist who's drawing every creature from Lovecraft's stories and posting them on a blog. What an amazing task. When I popped over for a look I was suprised to see creatures I've never heard of, such as the Yakith Lizard. "Where was that mentioned?", I thought, so did a bit of research and couldn't find it in any of the texts I have. Please post a comment if you know what story it appeared in.
