words: they say the long tail tips the scales

Adds eailed critters and scaly ones. No anole was harmed (it was already
in the list), and the loris was turned away at the door for being
suspiciously tailless.

Removes a word that was misread/misinterpreted and starts a rejection
list in the test suite.
