A single SYNAPTOMYS BOREALIS found (in Holocene birch phase sediment) among 10s of thousands of 

 small mammal remains. It was not found in Pleistocene deposits. Currently inhabits the area.

For SYNAPTOMYS BOREALIS: 2 locations in central BC; female w/ 4 embryos taken 15 May; all trapped in 

 runways through VACCINIUM; associated species included MICROTUS PENNSYLVANICUS and 

 CLETHRIONOMYS GAPPERI.

 of mammals. N. Amer. Fauna 19:1-45. 



Collected SYNAPTOMYS DALLl (=B0REAL1S) at several locations. At one location near Lake Lebarge they 

 were in long grass at the edge of a small pond, while other locations were in cold boggy places near small 

 streams. Gives description and measurements. 



Osgood, W. H. 1904. A biological reconnaissance of the base of the Alaska Peninsula. N. Amer. 

 Faima 24. 86 pp. 



Collected 24 SYNAPTOMYS DALLI (=BOREALIS) of all age and sex categories. Found much age variation 

 in skull measurements. Usually found in small colonies "in very wet swampy places, preferably in wet moss." 

 One area was a small boggy place partially filled with dead logs and branches and overgrown with moss. Says 

 they make runways slightly smaller than MICROTUS and usually in "moss rather than grass and weeds." Gives 

 description and measurements.
