than any other of our mice, and also, I think, more so than any of our 
Shrews. . 
11. Microtus pennsylvanicus. Meadow Mouse. Found to a.greater 
or less extent in all open fields, but reaches its greatest abundance in 
the wet meadows, where its habitat overlaps that of Oryzomys- It is 
not found in the woodlands. 
12, Fiber zibethicus. Musk Rat. Common in marshes and along the 
larger streams. A black color phase or variety occurs which is black 
above with lighter under-parts and cheeks than the common form. The 
black form is one-fourth or one-third as common as the ordinary brown 
phase. 
13. Scurius carolinensis. Southern Gray Squirrel. Tolerably common 
in all woodlands (Although I have made very careful inquiries I have 
been unable to find any evidence that the Fox Squirrel ever occurred 
here). es 
14. Sciwropterus arei Flying Squirrel.. Common. Strictly noc- 
turnal. a 
15. Tamias striatus. Chipmunk. They are fairly common about 
six miles west of Raleigh, but are totally absent from my immediate 
neighborhood. 
. Zapus hudsonius. Jumping Mouse. Rare. The one or two 
dozen specimens we have secured here come from upland, lowland, 
woods and open fields. An adult female and eight young were caught 
in a nest by some field hands, and brought to me, June 13, 1895. 
17. Sorex longirostris. Rare. Only seven specimens obtained so far. 
This species is found on comparatively high ground, not in swamps nor 
on the edges of them ; it has not so far been taken in woods, though one 
specimen was caught just on the edge of some woods. This i is the small- 
est of our mammalia. 
. 18. Blarina parva., Little Kivine Tolerably common. Is either 
only abundant in particular sitnations, or else it has become much 
scarcer in the last few years. Is found in open fields (and the edges of 
the more upland marshes to some extent). 
19. Blarina carolinensis. Carolina Blarina, Abundant, This species 
I believe to have become more abundant of late years; its distribution 
here is the same as that of Peromyscus leucopus, namely, everywhere, 
except in the wetter marshes, where Oryzomys palustris and Microtus 
pennsylvanicus are the only small mammals. ,
