XXXVIII. — Note on an undescribed Weasel from the Atlas 

 Mountains, and on the Occurrence of a Weasel in the 

 Azores. By G. E. H. Barrett- 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.

 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- 

 palmatuSy and allies it to P. n. ibericus and P. n. siculus.
