Lovecraft - Reptilan Dweller of Nameless City

The original one was too crocodile-like and the second one was too short. so here it comes, number 3

I tried to incorporate as much of the description as possible. It's spine does not need to hold it's weight so it can be incredibly flexible. It moves with interior of it's hands not making contact with ground, a bit like a gorilla. It's because their hands were delicate and used for careful, precise work and crawling on sand could damage them.

"They were of the reptile kind, with body lines suggesting sometimes the crocodile, sometimes the seal, but more often nothing of which either the naturalist or the palaeontologist ever heard. In size they approximated a small man, and their fore-legs bore delicate and evident feet curiously like human hands and fingers. But strangest of all were their heads, which presented a contour violating all know biological principles. To nothing can such things be well compared - in one flash I thought of comparisons as varied as the cat, the bullfrog, the mythic Satyr, and the human being. Not Jove himself had had so colossal and protuberant a forehead, yet the horns and the noselessness and the alligator-like jaw placed things outside all established categories."
