Dr. Weems notes that the following correction should be made to this article: what is described as
Hesperotestudo wilsoni (Auffenberg, 1964) should be Hesperotestudo williamsi (Auffenberg, 1964).
This correction includes the table, in which the H. wilsoni entry should be changed to H. williamsi
and the H. wilsoni entry should be deleted.
