Section of Middle axd Upper Lias Beds near to Milton. 



The letters A, B, C, &c., refer to the positioa of beds iu general 

 section . 



Ft. in, 



1. Soil passing into marly clay. Tlie clay, which is 

 nearly white, only occupies a few inches near the 

 base. A few fragments of Belemnites . . .26 

 E. — 2. Cephalopoda Bed. — An argillaceous limestone, 

 hard, nearly white, very fossiliferous, chiefly large 

 ammonites of the falcifer group badly preserved. 4 

 Amnionites serpentines (near to) Ajdyclii. 



„ iStranffivai/si (j^ommoii). 

 „ exaratus. 

 „ cornucopia. 

 Cerithium gradatum ? 



Y. — 3. A light-coloured, somewhat shaly bed, moderately 

 hard, scarcely to be distinguished from No. 2 in 

 appearance, and containing similar Ammonites of 

 large size. Numerous fish fragments in lower 

 portion 4 



G. — 4. Fish Bed. — A light-coloured nodular limestone, not 

 continuous, resting on or in thin shale. Fish 

 fragments common, also small Ammonites and their 

 aptychi 2 



H. — 5. Paper Shale. — A shale splitting into very thin 

 lamina, of a colour almost exactly like No. 3. 

 Fish fragments common . . . . .04 



I. — 6. Fish Bed in large slabs, most of which split easily 

 into two or three thinner ones. Fewer fish frag- 

 ments and other fossils in tliis than in No. 4 .02 



J. — 7. Paper Shale changing downwards into a more 

 clayey layer, and then a more sandy one, altering 

 to a reddish colour, and gradually losing its shaly 

 character 5 



8. Bluish shale or clay, somewhat sandy, verj' thin, but 

 quite distinct and continuous throughout the sec- 

 tion. Less regular in a horizontal direction than 

 the other beds 0| 



Transition Beds. 

 K. — 9. Bed sandy layer with a few badly preserved fossils, 



chiefly Belemnites 5 



L, — 10. Grey marl, or limestone, not very distinctly sepa- 

 rable from the sand above or the limestone below. 

 A great many Belemnites, perhaps six or seven 

 species, but much worn and often fragmentary. 

 Gasteropods less abundant here than in most 

 places where the same bed is found . . .07 

 Ammonites acutus (many) Arcomya vetusta (many). 



,, Holandrei Qmany) lyiina jjmictata. 



„ crassvs. Astai'te {two species). 



„ annulatus. Ithynclionellce (many). 



Gasteropods, Sfc. 



M. — 11. Rock Bed op Middle Lias, very fissile at the top, 

 upper surface very like, and has on it similar 

 fossils to the Transition bed proper. Manj' small 

 fiat pehhles, probablj' quite local, and fair amount 

 of crystallised carbonate of lime at the junction.
