W. H. Ball — Fossils of the Olympic Peninsula. 307 



Chione vespertina Conrad. 



Cytherea vespertina Conrad, Am. Journal Sci., 1848, p. 432, 



fig. 9. 

 Venus (Chione) vespertina Reagan, p. 181, pi. 1, fig. 8, 1909. 



The specimen identified by Reagan as C. vespertina is not in 

 the collection. 



Cyclinella 1 sp. 



Venus (Chione) angustifrons (Conrad) Reagan, p. 181, pi. 1, 

 fig. 9, 1909. 

 This fossil is an internal cast of obliquely oval form, thin 

 shelled, and showing a deep sharply angular pallial sinus and 

 unusually large posterior adductor scar, suggestive of the genus 

 Cyclinella. The figure is extremely inadequate. 



f Venus parapodema Dall. 



Venus (Chione) mathewsoni (G-abb) Reagan, p. 181, pi. 1, fig. 

 10, 1909. 

 The type specimen is a much dilapidated Venerid shell which 

 may possibly belong to V. parapodema, but certainly cannot be 

 identified with the Chione. 



Chione securis Shumard. 



Venus (Chione} temblor ensis (Anderson) Reagan, p. 182, pi. 1, 



fig. 11, 1909. 

 Venus (Chione) clallamensis Reagan, p. 183, pi. 1, fig. 13, 1909. 

 The specimen named V. clallamensis is the internal cast of a 

 young specimen of C. securis. 



Antigona olympidea Reagan. 



Venus (Chione) olympidea Reagan, p. 182, pi. 1, fig. 12, 1909. 



The specimen thus named is remarkable for its deep lunular 

 depression. The few particles remaining of the external layer of 

 the shell indicate a finely reticulate sculpture. The form of the 

 cast recalls Venus fordi Yates, of the recent Californian fauna. 



Marcia oregonensis Conrad. 



Saxidomus gibbosus (Gabb) Reagan, p. 184, pi. 2, fig. 14, 1909. 



The identification is correct, but Gabb 's name is a synonym of 

 Conrad's Cytherea oregonensis, 1848. 



Macoma calcarea Gmelin. 



Tellina albaria (Conrad) Reagan, p. 184, pi. 2, fig. 15, 1909. 



The type is a specimen of Gmelin 's species which is abundant 

 in these deposits, and is quite distinct from albaria.
