W. H. Dall — Fossils of the Olympic Peninsula. 305 



Art. XXIX. — Fossils of the Olympic Peninsula; by 

 William Healey Dall. 



In the Transactions of the Kansas Academy of Science, 

 volume 22, pages 131 to 238, Mr. Albert B. Reagan 

 described the Olympic Peninsula of Washington, dis- 

 cussed its geology and described and figured a number of 

 fossils from the Clallam and Quillayute formations. 2 



At that time, paleontological literature was rarely 

 accessible in that region, and there had been no modern 

 discussion of the late Tertiary fossils of the Oregon- 

 Washington area. It is not surprising therefore, that 

 identification of the species collected was difficult, and 

 sometimes failed in accuracy. 



Fortunately Mr. Reagan turned over his types to the 

 IT. S. Geological Survey, which transmitted them to the 

 National Museum where they are permanently preserved. 

 In working up the fossil faunas of the later Tertiaries of 

 the Xorthwest Coast, it became desirable to revise Mr. 

 Reagan's list and supply the modern designations, com- 

 paring his material with the types of Conrad and others 

 from the same general group. Mr. Reagan's species were 

 figured somewhat crudely in his memoir, but the types 

 were readily correlated with the figures, only two or three 

 being absent from the original series. 



His lists were distributed in two parts, one part 

 specially devoted to the species of the " Clallam" forma- 

 tion, and the other to those of the "Quillayute" 

 formation, so called. 



So far as the material in hand goes, the two faunas do 

 not seem to differ materially, the species being mixed at 

 Coos Bay, but for convenience in referring to Mr. 

 Reagan's memoir they will be separately considered here.
