A NEW CHAMOIS FROM THE APENNINES. 



BY GERRIT S. MILLER, JR. 

 I By permission of the Secretary of the Smithsonian Institution.] 



The United States National Museum has recently procured, 

 through the firm of Wilhelm Schliiter of Halle, Germany, two 

 skins anil skulls of Rupicapra from the Etruscan Apennines in 

 the region of Mount Comero and the headwaters of the Savio 

 River. They were at first supposed to represent Rupicapra 

 ornata, hut more careful examination shows that they have 

 none of the peculiarities of the Abruzzian chamois. While 

 agreeing with the alpine animal in erectness of the horns and 

 in the color pattern of the neck and throat, they differ so 

 noticeably in size of both incisiform teeth and cheek teeth from 

 the eleven specimens of Rupicapra rupicapra with which I have 

 compared them that there seems to be no reason to doubt that 

 tiny represenl ;i peculiar local form. This may be known as: 



Rupicapra fasuhi sp. nov.
