XXXVIII. — Note on an undescrihed Weasel from the Atlas 

 Mountains, and on the Occurrence of a Weasel in the 

 Azores. By G. E. H. Baijeett- Hamilton. 



Through the courtesy of the Director and Officials of the 

 British Museum of Natural History, I am enabled to publish 

 a short description of a weasel which is clearly distinguish- 

 able from the forms recognized by me in my paper published 

 in this Journal in January 1900. 



This form, which may be known as Putorius nivalis atlas, 

 is remarkable for its size and robustness, in which it is per- 

 haps only excelled by the true P. n. africanus of Desmarest. 

 On the other hand, the line of demarcation between the 

 colours of the upper and under surfaces, a highly character- 

 istic feature in the weasels, is widely different from that of 

 P. n. africanus and other forms with a similar arrangement, 

 such as P. n. numidicus, P. n. boccamela^ and P. n. sub~ 

 jjalmatuSy and allies it to P. n. ibericus and P. n. siculus, 

 b\ its tail, however, which carries a distinct terminal "pencil"
