Although these records may indicate recent range expansions, it is just as likely that these represent historical occupation by Spilogale putorius in this region and the species simply has not been detected previously.
Edward Roth, Howard Payne University, for donation of one specimen of Spilogale putorius to the Angelo State Natural History Collections.
The karyotypes of two specimens of Spilogale putorius interrupta from Texas and Mexico and two specimens of Spilogale putorius tropicalis from El Salvador are examined.
1 mi SE of Post, Garza County, Texas, one specimen of Spilogale putorius interrupta (TTU 17491).
Los Marranitos, Departamento de La Paz, El Salvador, one specimen of Spilogale putorius tropicalis (CM 111000).
The remaining seven species (Puma concolor, Urocyon cinereoargenteus, Mustela frenata, Mephitis macroura, Spilogale putorius, Conepatus leuconotus, and Procyon lotor) have been taken in both the Nearctic and Neotropical regions.

Finally, seven species are widespread and in both regions: Puma concolor, Urocyon cinereoargenteus, Mustela frenata, Spilogale putorius, Mephitis macroura, Conepatus leuconotus, and Procyon lotor.
However, the abundance of Spilogale putorius in the southern Appalachians is unclear.
Because the Appalachian Mountains of eastern Tennessee are representative of lands throughout much of the Appalachian chain (see Baily, 1980), this region is an appropriate site for studying population levels of Spilogale putorius.
Trap sites were selected by the presence of habitat similar to that in areas where Spilogale putorius was captured in preliminary trapping.
Captured Spilogale putorius were weighed to the nearest 5 g using a l000-g spring scale and four standard morphometric measurements (total length, length of tail, length of hind foot and length of ear) were taken on each animal.
One subadult and one adult male Spilogale putorius were captured during preliminary sampling.
The four Spilogale putorius were captured within 10 m of small streams in traps placed in relatively dense rhododendron thickets at elevations over 430 m.
Few reports of population density for Spilogale putorius are available.
