BULBUL,应该就是夜莺,“A songbird often mentioned in Persian poetry and thought to be a nightingale.”
“Some dreadful creeping thing from that horrid world outside”,应该是意指爬行的东西是低级动物,粗俗下作。意译一下吧。
“if any one even whispered a story, it just up and out with the truth at once, and shamed the culprit without remorse.” 这里少翻了最后半句。
