7 Geo. 5 Provincia Museum Reporr. Q 48 


“The question as to the exact position of the Acila gettysburgensis zone is debatable. 
Professor Weaver places it as the uppermost faunal 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 Haunibal, and by Weaver, are very 
closely related. Much more work, however, must be done before the sequence and relative 
importance of the different faunal 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 IX., Figs. II. and III. Tooth of Deeniestiin 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.
