Type locality. — Seville, Spain.

Diagnosis. — Intermediate in size between Mustela nivalis 

 nivalis and M. n. boccamela, though nearer the former (hind foot 

 in adult males, 30 to 35 ; condylobasal length of skull in adult 

 male, 39 to 43 mm.) ; colour of upper parts a buffy clay-colour, 

 not so dark as in the other races. 



Measurements. — Adult male and female from the neighbour- 

 hood of Silos, Burgos, Spain: head and body, 225 and 184; 

 tail, 59 and 53; hind foot, 27 and 21-8 ; ear from meatus, 15 

 and 13. Two adult males from Majorca, Balearic Islands : head 

 and body, 191 and 250 ; tail, 79 and 90 ; hind foot, 32 and 35. 

 Two adult males from Dehesa de Valencia, Spain : head and 

 body, 264 and 278 ; tail, 62 and 62 ; hind foot, 32 and 34. 

 Adult male from Seville, Spain (type) : hind foot (dry), 31-4.

Remarks. — The Iberian weasel appears to be more nearly 

 related to Mustela nivalis nivalis than to M. n. boccamela. It is 

 distinguishable from both of these by its paler colour.
