TERTIARY FAUNA OF FLORIDA 



bifid ; the anterior lateral inconspicuous ; the anterior left and posterior right 

 dorsal margins grooved to receive the edge of the opposite valve, the basal 

 margins entire ; the pallial sinus large, linguiform, ascending towards the 

 umbo. Length 7.75, height 7.5, diameter 4.0 mm. 



This odd little shell recalls Gonldia by its form and Dosinia by its sinus. 

 Nothing very close to it in the Miocene has turned up.
