TERTIARY AND QUATERNARY PECTENS OF CALIFORNIA. 



FAUNA. 



Pecten fauna. — The Pecten fauna of the Tejon group consists, so far as- 

 known, only of three species, P. calkinai n. sp., P. landesi n. sp., and /'. iitter- 

 radmtus Crahh. The first two probably belong to the subgenus ('hJainys, but are 

 not closely allied to any of the subsequent members of this group, so far as 

 known. P. interradiatus belongs to the Pr'opeannisium group and appears to lie 

 the precursor of such forms as P. i^tanfordensif^ P. vvii/landi, and P. clallaiiienntK. 



The following species have been found in the Tejon formation in different 

 parts of California:
