Abstract
A Wisconsin hunter, Mr. John Cerro of Madison, shot an unusually large cottontail (Sylvilagus floridanus) on November 21, 1955, in an upland habitat type. On dressing the animal it was found to be a pregnant female. He recognized this as an unusual occurrence and turned the carcass over to the Wisconsin Conservation Department. The humeral epiphysis of the rabbit was completely closed, indicating that she had passed her first winter.Keywords
