AMMONITES contractus. 
TAB. D.—Jig. 2. 
Spec. Char. Subglobose, umbilicated, 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 D undry : now in the collection of the Rev. 
Dr. Beeke, whose favours we have before had several 
occasions to acknowledge.
