30 POCKET GOPHERS OF THE UNITED STATES. 



S 



locally known as the ' Salamander.' The same name is applied to the 

 following' subspecies : 



The Florida Gopher (Geomys tnza florid 'anus) is a Florida form of 

 tuza, as its name indicates, and does not differ materially in external 

 appearance 



The Alabama Gopher (Geomys tuza mohilensis) inhabits southern 

 Alabama and northwestern Florida and is a strongly marked form, it 

 is very much darker than tuza. 



The Prairie Gopher ( Geomys bursarius) is the common Pocket Gopher 

 of the northern Mississippi Valley, from eastern North Dakota and 

 western Minnesota south to southeastern Missouri (see map 1, B). It is 

 a dark liver-colored animal with pure white forefeet, in sharp contrast 

 to the color of the surrounding parts, and has the longest claws of any 

 of the species having two grooves on the upper incisors (see plate II). 



The Plains Gopher (Geomys lutescens) is a pallid form of the bursarius 

 type, inhabiting the arid sand hills of western Nebraska and extreme 

 eastern Wyoming, and ranging thence southerly into northwestern 

 Texas (see map 1, C). 



The Louisiana Gopher (Geomys breviceps) inhabits the alluvial lands 

 of Louisiana, Arkansas, and eastern Texas, the typical form coming 

 from Prairie Mer Kouge, in Morehouse Parish. It extends thence 

 northwesterly up the valley of the Arkansas Eiver nearly to the Kan- 

 sas border (see map 1, D). It is a rather small dark species. On the 

 south, along the coast region of Texas, it splits up into the two follow- 

 ing subspecies : 



The Galveston Bay Gopher (Geomys breviceps sagittalis) inhabits the 

 Gulf coast of Texas about Galveston Bay. It is smaller than true 

 breviceps. 



Attwater's Gopher (Geomys breviceps attwateri) inhabits the coastal 

 plain and islands of Texas, from Nueces Bay northward to Matagorda 

 Bay, and ranges into the interior nearly to San Antonio. It is con- 

 siderably larger than typical breviceps. 



The Texas Gopher ( Geomys texensis) in its typical form inhabits central 

 Texas (see map 1, E). On the north and northwest it probably passes 

 into lutescens, while on the east it may intergrade with breviceps. It is 

 much smaller than bursarius or lutescens and has a pure white belly. 

 Irs upper parts are reddish-brown, paler than bursarius, but darker and 

 brighter than lutescens. 



The Sandy Gopher ( Geotrys arenarius) inhabits a very restricted area 

 in the upper Rio Grande \ alley in extreme northern Chihuahua, west- 

 ern Texas, and southern New Mexico (see map 1, G). So far as known 

 it is completely isolated, not coming in contact with any other species 

 of the genus. It is of medium size, has a relatively long tail, and the 

 upper parts are drab. 



The Padre Island Gopher ( Geomys personatus) inhabits Padre Island 

 and the adjacent coast of Texas from Santa Rosa southward, extend-
