MAMMALS OF MARYLAND 21 



Figure 5. — Distribution of Sorex longirostris longirostris. 



Habitat omd habits, — Although this shrew i^refers moist situations 

 such as bogs and damp woods, it has on occasion been taken on com- 

 paratively high ground. It is a rare species, and little is known of its 

 habits, although they probably do not differ much from those of S. 

 cinereios. An interesting sidelight on the specimen from Chesapeake 

 Beach, Calvert County, is a notation on the original label that says 

 "fell over cliffs to bayshore." 



Specimens examim^d. — Anne Arund-el County: Shadyside, 1. Calvert 

 Comity: Camp Roosevelt, 2; Chesapeake Beach, 1. Prince Georges 

 County: Hall, 1. District of Columbia : 1. 



Remarks. — It is interesting to note that, in the eastern United States 

 at least, the ranges of Sorex cinereu^ and Sorex longirostris do not at 

 present seem to overlap anywhere. North of a certain line (in Mary- 

 land this line lies in the Western Shore section between Washington, 

 D.C., and Shadyside, Anne Arundel County) all specimens collected 

 have been S. cineretos, whereas south of this line S. longirostris only 

 has been taken. There does not appear, however, to be any evidence of 

 intergradation between the species. Specimens of S. longirostris from 

 Calvert and Anne Arundel Counties, Md., are just as typical of that 

 species as are those from farther south in North and South Carolina, 

 whereas specimens from Rockville, only a few miles away, are clearly 

 S. cinereus. That the two are distinct species is further demonstrated
