Type locality. — Islay House, Islay Island, Scotland. 



Geographical distribution. — Islands of Islay and Jura, off coast 

 of south-west Scotland. 



Characters. — Size a little less than in M. erminea stahilis and 

 about equal to that of M. e. aestiva : condylobasal length of skull 

 in adult male, 47 to 50 mm. ; mandible in adult male, 27 to 

 29 mm. ; zygomatic arches unusually wide-spreading ; posterior 

 extension of palate relatively wider than in any of the other 

 known forms. 



Measurements. — External measurements of type (adult male) : 

 head and body, 254 ; tail, 105 ; hind foot, 43 ; ear from meatus, 

 22. Two other males from the type locality : head and bodv, 

 270 and 270 ; tail, 111 and 114 ; hind foot, 47 and 46. Two

 from Jura : head and body, 220 and 225; tail, 120 and 125; 

 hind foot, 45 and 46 "5. 



Specimens exatnined. — Thirteen, six from Jura and seven from Islay 

 (B.!M. and Cambridge). 



Itemnr1c.<>. — While readily distinguishable from the large true 

 atubilis of England, the Islay and Jura stoat will probably prove 

 to be more nearly related to the smaller form occurring on the
