INTRODUCTION. The purpose of this paper is to record as briefly as possible the purely scientific facts concerning the T ertiary Palaeon tology of ,ivestern Washington. A short account is given of the character and distribution of the several divisions of the Tertiary and their faw1tis. A northwestern Tertiary province is recognized and an attempt is made to interpret its history from the cJose of the Cretaceous to the present time. A total T ertiary invertebrate marine fauna of two hundred and forty six species bas been discovered. Eighty-four of these Me new and are described and figured for the first time. This report is preliminary to a more.
