18 Bangs TJie Weasels of Eastern North America. 



bullse ; distance from audital bullee to post-glenoid process much greater 

 than in the large weasels of the longicauda and noveboracensis groups. 



The skulls of the weasels of this group differ more widely from those of 

 Patorius proper than do skulls of the longicauda group or of the male nove- 

 boracensis. 



Remarks. When Professor Baird wrote his ' Mammals of 

 North America ' he had never seen a specimen of richardsoni, the 

 animal he called richardsoni being the small examples of novebo- 

 racensis, probably females. Since that time the National Museum 

 has accumulated a large series of this interesting weasel, but most 

 of the skins are in poor condition, unmeasured, unsexed, and ac 

 companied only by fragmentary skulls, which are inside the skins. 

 Still there are a few skulls in good condition accompanying the 

 skins taken in Alaska by the indefatigable Nelson ; measure 

 ments of these are given in the tables. A large proportion of the 

 known skins came from points in Alaska, but there are many 

 from stations that completely surround the type locality from 

 Fort Albany to Franklin bay. The principal localities are Fort 

 Albany, Fort Simpson, Fort Resolution, Fort McPherson, Big 

 Island, Fort Rae, Fort Good Hope, Hudson bay, Fort Anderson, 

 Anderson river, Peel's river, Yukon river, Franklin bay, Plover 

 bay, Fort Yukon, mouth of Porcupine river, Norton sound, St. 

 Michaels, and Point Barrow. They were collected for the most 

 part by E.W. Nelson, B. R. Ross, R. McFarlane, George McTavish, 

 J. Reid, R. Kennicott, L. Clarke, Jr., J. Lockhart, C. L. McKay, 

 and Lieut. P. L. Ray.
