Dolium nodosum. 
TAB. CCCCXXV1. and CCCCXXVIL 
Spec. Char. Obovate, ventricose, ornamented 
with transverse rows of knobs. 
Syn. Cast of a species of Dolium 1 Mantell 
GeoL Sussex , 196. 
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 probably 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 lse£@ 
wanting”, no other has however oceured.
