NORTH AMERICAN FAUNA 66 



Figure 7. — Distribution of Sorex dispar dispar. 



Some cranial measurements of the type as given by Jackson (1928, 

 p. 90) are: Condylobasal length of skull 18.2; cranial breadth 8.1; 

 interorbital breadth 3.5 ; maxillary toothrow 6.1. 



Habitat and habits. — This shrew prefers moist rocky areas and the 

 crevices between boulders, and large masses of rocks. It has also been 

 taken under moss-covered logs in damp coniferous forests. Mansueti 

 and Flyger (1952, p. 250) report that the three specimens they col- 

 lected on 6 September 1950, at Muddy Creek Falls, in Swallow Falls 

 State Forest, Garrett County, at an altitude of 2,200 feet, were taken 

 in snap traps placed on ledges in crevices of outcropping sandstone 2 

 or 3 feet above a small stream's level in a relatively cool moist hemlock 

 and rhododendron forest. Charles O. Handley, Jr. (1956, p. 435) says 

 that the Virginia specimen he took on Big Mountain, Giles County, in 

 September of 1955 was secured in a trap set about 12 inches below the 

 surface in a patch of talus. 



Very little is known of the habits of this species, but in all proba- 

 bility it differs little from other long-tailed shrews. Hamilton (1943, 

 p. 39) says that G. H. H. Tate collected a female with 2 embryos in 

 late August in the Adirondack Mountains of New York. 



Records and reports. — Garrett County: Swallow Falls State Forest,
