AMMONITES contractus. 



TAB. D.—Jig.2. 



Spec. Char. Subglobose, umbilicatedj radiated; 

 radii rising into tubercles upon the border of 

 the umbilicus, then dividing into three or four 

 branches that pass over the much rounded 

 front ; aperture oblong, arched. 



A SPECIES ornamented exactly like the last, but so glo- 

 bose that the inner whorls are almost concealed, the 

 sides of the shell appearing as if contracted together to 

 form a deep umbilicus. 



Found at Dundry : now in the collection of the Rev. 

 Dr. Beeke, whose favours we have before had several 

 occasions to acknowledge.
