2IO liunu'l : Xotes on I he Upper C/i<i/k of Lincoln shire. 



There is a very interesting- exposure in tlie quarry a mile 

 west of Ulceby, which shows about 30 feet of comparatively 

 soft chalk, with bands of imperfect tabular flint. The beds have 

 a slight easterly dip. The fossils found here were : — ■ 



Micnister cortestiidinarium. Rhynchonella cnvieri. 



Holaster (either planus or Terebrutiilina lata, 



placcntii). Terebrainlu carneti. 



Rhynchonella reedensis ? Ostrca vesicnlaris. 



From this point northward to the H umber there are numerous 

 quarries showing- similar beds to those already mentioned, but 1 

 have not yet had an opportunity to make a leng^thy examination 

 of them. A very good section is to be found in a large quarry 

 three-quarters of a mile west of Thornton, where there are 

 about 35 feet of hard white chalk with immense tabular bands 

 of dark flint. Fossils are rare, and the only ones found here, 

 and in one or two other pits in the vicinity, were : Inoceranms 

 cuvien\ Rhynchonella cnvieri^ Terebrafnlina lata., Terebrattilina 

 striata, and Cidarls spines. 



There are, however, some very large quarries just south of 

 Barrow, and here I found : — 



Echinocorys scutatus. Kingena lima. 



Terebratnlina lata. Rhynchonella reedensis. 



Terebratula sp. Holaster placenta., 



Rhynchonella cnvieri. Inoceratnus sp. 



As regards the zoological characteristics of the Upper Chalk 

 of Lincolnshire it will be noted that while there is a general 

 resemblance to that of the same horizon in the south of England, 

 there are, on the other hand, certain local peculiarities. 



The Lamellibranchs found in these beds do not call for any par- 

 ticular comment, with one exception. The example of Septifer 

 lineatus which I found at Fotherby is the only specimen hitherto 

 obtained from either Lincolnshire or Yorkshire. It is a species 

 characteristic of the 'Chalk Rock,' and is described by Mr. H. 

 Woods in his paper on 'The Mollusca of the Chalk Rock.' * 



Among the Brachiopods Terebratula carnea is the most 

 common. Terebratula seniiglobosa, a form \ery common in the 

 Middle Chalk, is extremely rare. I have obtained three speci- 

 mens of Terebratula from the quarr\' at Fotherby, which Dr. 

 Kitchin says are probably referable to this species. They differ 

 very much in both size and forni from the normal type, and he
