Besides the foregoing, many minute young or new forms hare 

 been obtained from the Ponton shelly beds ; but which, although 

 often well preserved, it has been found impossible to identify with 

 known species. 



Denton. 



I will not attempt to trace the occurrence of these beds further 

 north; but will incidentally draw attention to the fact that at 

 Denton (6 miles south-west of Grantham, and 18 miles due north of 

 Morcot), is a bed of the Lincolnshire Limestone ; which has yielded 

 nearly the same suite of fossils as the last-named place (including 

 the fine example of Pterocera Bentleyi mentioned in my notice of the 

 Colly weston Slate beds), with the addition of several univalve and 

 bivalve forms, and some beautiful and probably new varieties of 

 Coral.
