 shortened and widely expanded anteriorly, rapidly becoming com- 

 pressed posteriorly; angular process of mandible short, blunt and

 Txpe locality. Lake Drummond, Dismal Swamp, Virginia. 

 Geogr. Distr. Only known from Dismal Swamp, Virginia. 

 Genl. Char. Similar to F. zibethicus, but darker; incisors and 



molars larger. Skull: brain case elongated posteriorly; squamosal 

 root of zygoma more sloping; teeth heavier and larger. 



Color. Upper parts abdomen and chin blackish brown; rest of 

 pelage whitish, or pale drab tinged with fulvous. 



Measurements. Total length, 567; tail vertebra;, 244; hind

*Tlie specimen, whose skull is shown in Fig. No. 49, came from Blindman River, Northwest 

 Territory, and is apparently properly referable to F. zibethicus, the skin also not differing percepti- 

 bly from other examples of that species; and this would seem to indicate that if F. spatuliis is dis- 

 tinct, both species are found in practically the same locality!
