iNAUTlLUS expansus. 



TAB. CCCCLVIIL— ^o^. 1. 



Spec. Char. Subglobose, uinbilicated, finely 

 striated ; umbilicus small ; sides of the 

 aperture expanded. 



A SMALL Nautilus with sharp curved striaa following the 

 lines of growth ; the aperture is so much expanded 

 laterally with the columella, as to make the axis con-

 small and nearly cylindrical : the septa cross the striae, 

 and are nearly straight edged at the front.

 but I think can hardly have been mistaken for it. The 

 specimen in our Museum, is a cast in Chalk-marL
