There is a total of forty-five species occurring in this forma- 

 tion. Out of the total fauna thirty are new species. The base 

 of this formation is unknown. Its known thickness is at least 

 five hundred feet. Future sflidies may show this to be really 

 a part of the Tejon formation". 



Dr. Weaver's present opinion is that the Cowlitz phase is 

 uppermost Tejon and that it is to be correlated with the Sipho- 

 nalia sutterensis Zone. 



Mr. Bruce Martin described conditions at the two principal 

 collecting localities 182 and 183, Cal. Acad. Sci. as follows: 



"Locality 182 is on the west bank of the Cowlitz River im- 

 mediately south of the eastward bend about one and one-half 

 miles east of Vader, Washington. This is Professor Weaver's 

 University of Washington locality 1. The formation here 

 consists of blue sandy clay or mudstone. There are a few 

 prominent strata of concretionary sandstone interstratified with 

 the clay. The strike is N. 40° W., dip 5°-10° N. The forma- 

 tion extends southward down the river for some distance and 

 fossils mav be obtained from the banks for a half mile or more. 



The tops of the hills between Vader (Little Falls) 



and Olequah are mantled with basalt and the sandstone is 

 exposed only in the creeks which have cut through the lava 

 cap. 



Locality 183 is in the west bank of the Cowlitz River about 

 one and three-fourths miles southeast of Vader (Little Falls), 

 Washington, about one-half mile south of Locality 182".
