This is a decidedly tropical fauna, with Nautilus, Macrocal- 

 lista, giant Venericardia, Crassatellites, Conus, Ficus, Fusus, 

 giant Turritella, Rimella, and Galeodea all represented in the 

 tropics by kindred forms. This tropical belt extended up to 

 Puget Sound, and the Alaskan waters were probably cooler. 



The Tejon fauna is of Caribbean origin, and the zone of 

 Venericardia planicosta represents the last great migration 

 from the Atlantic to the Pacific. Many Tejon species are 

 identical with, or closely related to, forms in the Eocene of the 

 Gulf states. 



Kenai flora (Unga Island, Shumagin Islands, Alaskan 

 Peninsula, lat. 55° N.). This flora was listed by W. H. Dall*' 

 as Oligocene, while A. H. Brooks*^ considers it as Eocene. 

 The forms known are: Taxodium, distichum miocenicum Hr., 

 Glyptostrobus europceus Hr., Sequoia nordenskioldi Hr., Quer- 

 cus pseudocastanea Gpt., Castanea ungeri Hr., Populus glandi- 

 fer Al. Br., Liquidambar europceum Al. Br., Betula, Alnus,
