174 Arthur Burnet — The Upper Cholk of North Lincolnshire. 



Similar beds also occur in the upper part of a pit a quarter of 

 a mile south-west of North Ormsby. At the base of the pit, below 

 the lowest band of imperfect flint, there is a bed of cream-white 

 chalk, which yielded Micraster Zeshei. Other fossils found in this 

 pit were : — 



Holasfer, sp. Ostrea vesicularis. 

 Mngas pumihts. ,, sp. 



Jihi/»('hoiii-//ii. Cuvieri. Inoceramus, sp. 



TerebratuUtta lata. 



It is not improbable that the upper beds of this pit, together 

 with those seen at Lambcroft, belong to the zone of Micraster 

 cortestudinarium. 



A quarry half a mile east-south-east of North Ormsby yielded 

 the following : — 



Terebratula carnea. Rhynchonella Cuvieri. 



Kingena lima. Inoceramus Cuvieri. 



Terebratulina lata, Holaster placenta. 



Another quarry in the same village, to the north of the church, 

 showed a similar section to that seen at Fotherby, with the following 

 fossils : — 



Terebratula carnea. Ananchytes scufatus. 



Rhynchonella Cuvieri. Inoceramus, sp. 



Serpula, sp. (small spiral). 



The samelithological features were visible in a large quarry about 

 half-way between North Ormsby and Wyham, from which I obtained 

 Uliynchonella Cuvieri, Kingena lima, Holaster planus {or placenta), and 

 a spine of Cidaris. I also found spines of Cidaris sceptifera in 

 a small pit at Wyham. 



There are two quarries at Cadeby, both of which show a course 

 of the imperfect flint previously mentioned. The only fossil that 

 I could find was Ostrea vesicidaris ; the lithological character of 

 the beds, and their extremely unfossiliferous nature, suggest the 

 possibility that they belong to the zone of Micraster cortestudinarium. 



Further west, in a quarry at Wold Newton, I found Magas pumilus, 

 Bhynchonella Cuvieri, Holaster planus, and Inoceramus, sp. 



Few fossils could be found in the pits at Hawerby, Eavendale, 

 and Hatcliffe. At Hawerby I found Terebratula carnea, Ostrea 

 vesicidaris, and Inoceramus, sp. From East Ravendale I obtained 

 a broken echinoderm, which is possibly Ananchytes scutatus. 



The quarry near Beelsby Church yielded Terebratula carnea, 

 Bhynchonella Cuvieri, and a species of Inoceramus. 



The quarry half a mile south-west of Irby Church shows a section 

 of hard chalk with tabular flints, and scattered flint nodules. Here 

 I found : — 



Holaster planus {or placenta). Spondylus latus. 



Terebratulina lata. Inoceramus Cuvieri. 



Rhynchonella Cuvieri. 



Continuous bands of dark flint are also seen in a pit to the 

 south-east of Riby. The fossils found here were Holaster planus
