In consequence of the imperfections of the only re- 

 mains we have of this extraordinary fossil, we can give 

 but short details of its form. It is about four fifths of 

 its length wide, the spire is very short and consists of 

 only two or three turns ; it is marked with a few trans- 

 verse, prominent, rounded bands, and a few longitudinal 

 striae ; the bands upon the body of the shell are divided 

 into obtuse, not much elevated but large knobs, that are 

 but badly preserved ; the base and part of the columella 

 are lost with the surrounding Chalk, that has been 

 broken away ; there is no vestige of the shell itself, and 

 the cast prol)ably exhibits its inner surface only. 



Soon after the discovery of this noble specimen, in 

 Clayton Pit by R. Weeks Esq. of Hurstperpoint in 

 Sussex, it was kindly lent to Mr. Sowerby ; it would 

 have been figured before, but hopes were entertained 

 of finding specimens to illustrate such parts as are here 

 wanting, no otlier lias however occured.
