SCHAPHITES. 



TESTA concamerata, involuta, anfractibus primis 

 minoribus, ultimo dilatato et elongate, demum 

 attenuate et inflexo, septis lobatis et sinuosis. 



A Fossil Genus established by Parkinson and related to 

 Ammonites, but differing much in its general form in 

 consequence of the remarkable extension and inflexion of 

 its last chamber. It is found, but rarely^ in three conti- 

 guous beds, the Chalk, Chalk marl and green Sand: in 

 Sussex, Wiltshire and near Rouen in Normandy. 



Shell chambered, involute, its first volutions small 

 and increasing very gradually; its last elongated and dilated 

 or expanded, and then diminishing and turned inwardly; 

 the divisions of the chambers lobed and sinuous. It is 

 probably in a great measure, if not wholly internal; of 

 course nothing is known of its animal, though it is supposed 

 to be cephalopodous.
