In this focused study the authors untangle a long‑standing mix‑up in the classification and range of two common North American cottontails. By revisiting historic museum collections and painstakingly cross‑checking catalogue numbers, they reveal where early 20th‑century notes led to misplaced subspecies labels, especially in Nebraska’s borderlands. The narrative walks listeners through the detective‑like process of sorting field cards from actual specimen tags, illustrating how a single transcription error can ripple through decades of scientific maps.
The paper then shifts to a side‑by‑side anatomical comparison of the Florida cottontail and the Audubon cottontail, highlighting subtle differences in skull shape, ear length, and foot dimensions. These details clarify whether the two forms truly intergrade along the eastern Rockies or remain distinct. Throughout, the authors blend historical context with fresh data, offering a clear view of how meticulous taxonomy underpins reliable wildlife distribution studies.

A careful mid-20th-century mammalogist, this author helped map and classify North American mammals in a body of work still associated with classic zoological reference books. Much of the writing is technical, but it reflects a deep interest in how species vary across regions.
