MAMMALS OF MARYLAND 147 



Figure 48. — Distribution of Mustela erminea cicognanii. 



Male and female long-tailed weasels are larger than male and female 

 ermines, but since the males in both species are larger than the fe- 

 males, a large male ermine may approach in size a small female long- 

 tailed weasel. 



Measurements. — Hall (1951, p. 119) gives the averages and extremes 

 of external measurements of seven adult and subadult males from 

 New York and Pennsylvania as follows: Total length 266 (240-295) ; 

 length of tail 74 (66-80) ; length of hind foot 36 (33-39). He gives 

 the external measurements of 12 adult and subadult females from 

 Maine and the area south to central Pennsylvania as: Total length 

 243 (225-260) ; length of tail 63 (55-72) ; length of hind foot 29.8 

 (26-32). 



Some cranial measurements given by Hall (1951, pp. 434-435) of 

 nine adult and subadult males from New York and Pennsylvania are : 

 Basilar length (of Hensel) 35.7 (33.8-37.6) ; zygomatic breadth 20.3 

 (19.0-20.6) ; interorbital breadth 8.6 (7.7-8.9) ; mastoidal breadth 

 18.2 (17.3-18.8) . Four adult and subadult females from New York and

(31.4-33.3); zygomatic breadth , , 17.5, 18.0; interorbital 



breadth 7.5 (7.2-7.8) ; mastoidal breadth 15.7 (average of 3, 15.3-
