Corley is an acquaintance of Stephen's and son of the Dublin Inspector. He appears in "Eumaeus." He tells Stephen that Lenehan and his other friends deserted him and now he has no place to sleep. He also asks Stephen if he know where he might get a job as he is currently out of work. Stephen gives him half-a-crown, and Corley thanks him for his generosity, though Bloom thinks that Stephen shouldn't part with his money so early.
In terms of correspondence with the Odyssey, Corley corresponds to Melanthious, the goatherd who persecutes Odysseus when he returns in disguise. After Odysseus takes care of the other suitor and betrayers, he cuts off Melanthious's nose, ears, hands, and feet, and feeds his genitals to the dogs. Needless to say, Bloom is more forgiving in Ulysses.
