Sorex cinereus fontinalis HoUister 



Sorex fontinalis Hollister, Proc. U.S. National Museum, 40: 378, 

 17 April 1911. 



Type locality. — Cold Spring Swamp, near Beltsville, Prince Georges County, 

 Maryland. 



General distribution. — Piedmont and Coastal Plain of Pennsylvania, Maryland, 

 aui northern Virginia. 



Distribution in Maryland. — Piedmont, Western Shore, and Eastern 

 Shore sections. 



The characters of this race seem to be best developed in the lower 

 Piedmont section near Washington, D.C. (near the type locality). 

 Specimens from the Coastal Plain sections of the Eastern Shore and 

 upper Western Shore are less typical and apparently represent inter- 

 grades with S. c. cinereus^ which is distributed to the northeast in New 

 Jersey. In the upper Piedmont the subspecies intergrades with S. c. 

 cinereus. No specimens of masked shrew have been taken in the 

 southern part of the Western Shore section (Calvert, St. Marys, and 

 Charles Counties) and perhaps the species does not range this far 

 south in the State.
