Geo. 5 Provincial Museum Report. Q 43 



" The question as to tlie exact position of the Acila gettysburgensis zone is debatable. 

 Professor Weaver places it. as the uppermost favmal zone of the Oligocene. 



'■ My study of the Oligocene fauna of middle California, together with that of Oregon and 

 Washington, appears to me to show that the faunas of the different horizons of the Oligocene 

 of Oregon and Washington, as recognized by Arnold and Hannibal, and by Weaver, are very 

 closely related. Much more work, however, must be done before the sequence and relative 

 importance of the different fauna] zones can be established for a certainty." 



Plate IX.. Fig. 1. View of fossiliferous sandstone cliff near the mouth of Coal Creek, Sooke. 

 The low Tertiary cliff is covered by heavy glacial deposits with heavy growth of timber. Erosion 

 is going on with great rapidity, leaving ice-worn boulders on nearly level rocky beach, which 

 extends far out to sea at low water. 



Plate IS., Figs. II. and III. Tooth of Desmosti/lus. believed to be of the species hesperus 

 of Marsh. The tooth is formed of several cylindrical pillars, each consisting of a thick layer 

 of enamel enclosing a small body of dentine. The grinding surface shows a circular depression 

 at the end of each of the principal pillars, the lip of which is formed by enamel, and the central 

 pit is excavated by wear into the softer dentine. 



Until this tooth was found the Desmostylus was only known to occur in America in Oregon 

 and California : outside of America it has also been found in Japan.
