The extinct fauna of Crete and its relation to the Minotaur legend, C. 

 Keller {Vrtljschr. Naturf. Oesell. Zurich, 5// (1909), No. S-J/, pp. Ji2'i-'i3o, fig. 

 1). — From a study of fossils found on the island, the author concludes that 

 8us scrofa, Cervus elaphiis, Capra wgagrus. Bison europwus, and Bos primi- 

 genius existed there as wild animals in the time of Minos. Bones of tame 

 swine were found, but are supposed to belong to 8iis indicus. The palace at 

 Knossos contains works of art, in which Bos primigenius is depicted as domes- 

 ticated and used in bull fighting in premycensean times. It is suggested that this 

 gave rise to the Minotaur myths.
