According to Dinnik, the general colour in winter is

Horns ibex-like, subtriangular in section, and curving

 in fig. 37), and more or less distinct knots on front surface ; 

 beard, when fully developed, elongated in its middle portion 

 and narrow and straight in summer. 



Horns from the lihsetian Alps (fig. 37) present a close

 to have been found, with other skulls and skeletons, in a 

 glacial moraine at Lauternabach, in the Roseg district, and
