Astarte (GoodaKia ?) americanaDall, PI- 32, Fig. 30 



Astarte {Goodallia) auiericana Dall, Trans. Wag., Ill, 1903, p. 1496, 

 pi. 56, fig. 5. 



DalVs original description. — Shell small, compressed, nuculoid in 

 form, anterior slope short, directly descending, posterior longer, arcuate ; 

 base arcuate, beaks low, lunule lanceolate, impressed, escutcheon obscure ; 

 surface finel}^ concentrically striated ; hinge of left valve with two diverg- 

 ing cardinals, inner margin smooth. Length 4.0, height 3.25, diameter 

 1.5 mm. 



A single, somewhat worn left valve is all that we possess of this spe- 

 cies. The form is very different from that of the Parisian species, but the 

 hinge appears to be the same, the anterior tooth having been broken off 

 and only its base remaining. The pallial line is certainly unsinuated, and 

 taking all the circumstances into consideration it seems probable that this 

 species should be referred to Goodallia^ though it has somewhat the aspect 

 of a Leptonaceous shell.

Our Claiborne collections have furnished no additional spec- 

 imens of this little species. Hence we have reproduced Ball's 

 illustration and have quoted his description verbatim.

 in the foregoing text, may well be deleted from Eocene literature
