Foor or five turns are distinguishable in this Ammonite; 
its diameter rather exceeds three times the length of the 
mouth, which is twice as long as wide; the radii are 
largest and most distinct near the margin, on the other 
parts they are often obscure, they are very numerous, 
each forms two semicircles reversed to one another, the 
ends of which join in the obscure, or rather wide and 
shallow, furrow that runs round the sides. The oblique 
flattened surface that forms the inner edges of the 
whorles, slants from the centre, and becomes a strong 
character.
