Morris — Oolites of Northampton, ^c. 99 



I have sought to commemorate the successful labours of the late 

 Mr. Bean in exploring the fossiliferous beds of the Yorkshire Oolites, 

 by dedicating this genus to him.

Shikes. 



ByJ. Morris, F.G.S. 



ALTHOUGH the geology of the Midland Counties has been con- 

 siderably elucidated, still there appear to be some points con- 

 nected with the position and nomenclature of the Lower Oolites 

 which require re-examination. 



Having long since published some observations upon this district,^ 

 in which the position of certain beds was somewhat doubtfully given, 

 I am desirous to recall attention to the conclusions then arrived at 

 by myself, as well as to others bearing upon the district subsequently 

 published.^ 



The geologist who has personally examined the strata between 

 the Upper Lias and Cornbrash, as they range between Gloucester- 

 shire and Yorkshire, or who may have become acquainted with them 

 from the writings of Strickland, Hull, Lycett, and Wright, in the 

 south-western area, and of Phillips, Williamson, Oppel, and Leckenby, 

 in the northern, must be aware of the great lithological (and in part 

 palaeontological) differences which exist in the two districts, and 

 would probably infer, that beds of an intermediate character might 

 be found in the countries lying between them.^ 



In the south-western area the Lower Oolitic series attains its 

 normal development both in formations and thickness, and j)resents 

 a character almost entirely marine. This series consists mainly of 

 limestones with intercalated sandstones, and clays, rich in Testacea, 

 Corals, and Echinoderms, with occasional traces of land-plants in 

 the Stonesfield slates of the Cottes wolds, which become more 

 abundant in the similar beds of Oxfordshire, where they are associ- 

 ated with Eeptiles, Fishes, and Terrestrial Mammalia. 



The series attenuates rapidly as we proceed easterly, (as pointed
