LÖNNBERG, STUDY OF THE VARIATION OF EUROPEAN BEAVERS. 7 



kindness of Professor Dr. Kurt L ampert I ha ve had the 

 pleasure of examining three more Beaver skulls belonging to 

 the R. Naturell History Museum of Stuttgart. These skulls 

 are labeled 



[no.] »1069 $. Moldau bei Wittingau. Febr. 1864.» 



[no.] »208 ?. Donau bei Ulm. 1849». 



[no.] »2749. Donau bei Regensburg. 1854.» 



Fig. 2. Skull of a Beaver 9 from Ulm (Mus. Stuttgart). 



These are all of them adult skulls although not very 

 old, the one from Regensburg being the youngest in the lot. 

 In spite of their different origin, they evidently belong to 

 nearly the same type.
