On Two Tertiary Faunas. 



the occurrence of fossils in concretionary boulders is not uncom- 

 mon at Astoria and at various other points on the west coast, 

 where the later Tertiary rocks are exposed. In answer to a ques- 

 tion as to the character of the fossiliferous boulders, Dr. Newcombe 

 stated recently that it is "possible that they are concretionary, but 

 he remembers having seen along with them, in the fossiliferous 

 beds, large quartz and diorite pebbles and water-worn boulders. 

 Whether water-worn or concretionary, it is pretty certain that the 

 fossiliferous boulders are all of the same origin, since the matrix in 

 which the fossils are imbedded seems to be the same in all cases. 

 We may safely assume that the species cited here as occurring in 

 the Carmanah Point beds all belong to the same fauna, which may 

 have flourished in situ at the time the Carmanah Point sediments 

 were being deposited, or may have lived in an earlier period, at a 

 locality not far distant, from which the fossiliferous boulders were 

 derived for the formation of the Carmanah Point conglomerate.
