Summary

4 of the 5 subspecies ofGeomys pinetis were karyotyped. All specimens examined had a diploid number of 42 and a fundamental number of 80. This karyotype was compared with the described karyotypes of other species ofGeomys and was considered to be derived from an ancestoral form having a karyotype of about 70 acrocentric elements.
