The Recent Mammals of Tamaulipas, Mexico
Excerpt: ...my knowledge, no one other than Goldman has critically studied specimens of this pocket gopher, nor have specimens other than those listed in the original description been reported up to now. In 1953, Gerd H. Heinrich collected a series of 19 individuals one mile south of Altamira. These specimens were compared (by E. R. Hall in March, 1962) with the holotype and paratypes of G. p. tropicalis and were found to be indistinguishable. Careful comparisons of the specimens from one mile south of Altamira with topotypes of G. personatus personatus (and specimens of other subspecies) indicate that tropicalis differs from personatus in a number of important characters, some of which tropicalis shares with Geomys arenarius of the Rio Grande Valley and adjacent areas in Texas, New Mexico, and Chihuahua (see Table 2). Table 2.
