2o8 Bitrnct : Xotcs on I he I'ppcr C/ialk of Lincolnshire. 



One of the most soutlierly exposures of Upper Chalk is the 

 qnarry at Boswell, near Xorth l')lkini,'-ton. As Mr. Hill had 

 previously visited this quarry, and had fully described it in his 

 note in the Geological Magazine for September, 1902, I did not 

 make a leng-thy search for fossils here. They are, however, 

 not difficult to find in this pit, and, so far as I know, it is the 

 only quarry in Lincolnshire where Micrastcrs are at all common. 

 Two other very typical sections oi Holaster planus chalk occur 

 at Fotherby. The first of these, three quarters of a mile W.S.W. 

 of the villag'e, shows about 25 feet of hard white chalk with 

 bands of dark tabular flint, and a seam of dark yellow marl. 

 From this quarry I obtained the following fossils : — 



Septifcr liucatus. Echinocorys scutatus. 



Jnoceranins brongniarii. Goniastcr sp. 



Plicatula sigillina. Rhynchonella ciivieri. 



Ostrea vesiculans. Tc re brat 11 la carnea. 



Ostrea normaniana. Terebratula setniglobosa. 



Holaster planus. Terebratulina lata. 



Holaster placenta. Kingena lima.* 



Cyphosoma (spine), 

 As in many other quarries on this horizon, fragments of very 

 large Inoceramus shells are somewhat abundant. 



The other quarry lies a little to the west of Fotherby Grange, 

 and here I found Holaster planus, Rhynchonella cuvieri, Tere- 

 bratula carnea., Terebratulina lata, and Terebratulina striata. 



At North Ormsby there are three quarries, all showing the 

 same series of beds. They are situated as follows : half a mile 

 S.S. E. of the Church ; about 360 yards north of the Church ; 

 and three-quarters of a mile N.N.W. of the village. From 

 these sections I obtained the following : — 



Inoceramus cuvieri. Rhvnchonclla cuvieri. 



Holaster planus. Terebratula carnea. 



Holaster placenta. Terebratulina lata. 



Kchinocorvs scutatus. /\iu<^e)ia limn. 



On the high ground to the west of the village there is a 

 small pit showing bands of the imperfect tabular flint already 

 referred to. This quarrj' yielded the following : Micraster 

 corbovis, Holaster placenta, R/iynchouella cuvieri, Ostrea (a 

 small species), Ostiea vesicularis, and KinQcna lima. 



I'^urthcr west, at I.amhrroll, there is anothtM- section where
