What is "mygale avicularia"

Mygale \Myg"a*le\, prop. n. [L., a field mouse, Gr. ?.] (Zo["o]l.) A genus of very large hairy spiders of the family Ctenizidae, having four lungs and only four spinnerets. They do not spin webs, but usually construct tubes in the earth, which are often furnished with a trapdoor.

Some of the species are erroneously called tarantulas, as the Texas tarantula ( Mygale Hentzii).
