NOETH AMERICAN FAUNA. 



[No. 38. 



typical of aquaticus. Dismal Swamp, Va., produces a mole which 

 is as large as the typical form and has a little more tendency toward 

 a mummy brown shade on the back. Material from the Appa- 

 lachian Mountain region is entirely too scarce to determine the exact 

 relationship and area of intergradation of aquaticus with S. a. machri- 

 nus; a specimxcn from Koan Mountain, N. C, shows a very slight 

 approach toward maclirinus in size. A skin without skull from 

 Walden Ridge, Tenn., is here rather arbitrarily referred to aquaticus 

 on account of its size and color.
