In a 1978 revision and expansion of his book, which includes material on the rubberado porcupine, the snoligoster, the three-tailed bavalorus, the squonk, and many other creatures, Wyman devotes four pages to the jackalope. In a turnabout from his earlier claims of a North Country origin for the antlered hare, he says, "The center of its vast range seems to be Wyoming." Evidence of wide dispersal of "Lepus antilocapra wyomingensis" from its original range, he claims, are labels such as "Tioga, Pennsylvania," and "Hongkong" stamped on mounted jackalope heads in barrooms across the United States.
