The Lower Cretaceous Series. — This series, as developed 

 in Lincolnshire, is of extraordinary interest to geologists, 

 both from a stratigraphical and palseontological point of view; 

 Recognising this fact, two days were set apart for the examina- 

 tion of these rocks. The cuttings on the Great Northern 

 Railway between Withcall and Willingham occupied the first 

 day, and the western escarpment, where occurs the natural 

 outcrop of the beds, the second day. 



The Lincolnshire Lower Cretaceous series is particularly 

 instructive to geologists familiar with the Yorkshire coast. At 

 Speeton the beds between the Kimeridge Clay and the Chalk 

 consist entirely of dark clays, only varying in such minor 

 characteristics as colour, quantity of pyrites, or the number and 

 nature of the contained septarian nodules. 



In Lincolnshire the beds of identically the same stratigraphical 

 age consist of sandstone, limestone, and beds of shale, the 

 whole series forming a very instructive study in comparative 

 geology. 



Although the lithology of the two areas (Speeton and Lin- 

 colnshire) differs so widely, it has been proved that the life-zones 

 as defined by the belemnites of Speeton obtain also in Lincoln- 

 shire. The general fauna of the two areas is also remarkably 

 similar, though, as might be expected, the species differ in 

 relative abundance. 



The photograph on Plate XVIL, Fig. i, shows the section 

 exposed at the west end of the Withcall tunnel. Here is seen 

 the junction between the Upper and Lower Cretaceous series, 

 viz. : — The Grey Chalk (at the top), Red Chalk, and Carstone. 



We are indebted to Mr. Godfrey Bingley for taking the 

 photographs for these notes, and also to our Lincolnshire friends 

 for their assistance in making the excursion both enjoyable 

 and profitable. 



FISHES, 



Angler Fish at Qoole. — A small specimen of the Angler 

 {Lophins piscatorius) was captured at the mouth of the Don on 

 the 20th May : it lived for some hours. Some of our sailors 

 who have been on trawlers know it by the name of Monk fish.. 

 It is strange that it is also known as Devil fish. This specimen 

 is only eight inches in length. One was taken at Whitgift on 

 27th May 1884, and was twenty inches long. The dates suggest 

 a migratory habit. — T. Bunker, Goole, 22nd May 1905.
