Remarks. Figure 25 of plate 75 is a fac-simile of 

 Orbigny's figure of Auricula ovula. It is a good represen- 

 tation of our Florida shells. 



West Indian specimens are well known in cabinets. I 

 know of no American specimens, with the exception of 

 the few collected by Mr. Bartlett. 



PI. 79, fig. 6, may represent a variety of this species. It 

 is from Texas.
