The shell of Panopaea, which is of large size, is closely allied to that 

 of Solecurtus. It is described as oval, equivalve, inequilateral, and 

 gaping widely at both ends ; there is a single acute cardinal tooth in 

 each valve, and the ligament is external, attached to a large fulcrum ; 

 the muscular points of attachment are distant from each other, and the 

 palleal impression exhibits a large sinus.
