MOORE — ab:n-ormal secondary deposits.

MM. Martin aud Terquem, from the sectioDs of tlie Cote d'Or and 

 the Gres calcarenx of Luxembourg and Hettange. The same Mol- 

 lusca continue upwards in thinner beds of stone, interposed be- 

 tween beds of clay, but they do not weather out so perfectly. On 

 the surfaces of the latter beds are many examples of Involutina 

 Uassica, Jones, which are also frequent in the Mendip mine, and 

 more rarely at Brocastle, and again at Stout's Hill. 



Eeturning again to theAvonside wharf section, and crossing several 

 steep fields above this quarry, Stout's Hill is reached. A large field 

 has, in former times, been completely quarried ; but there only re- 

 mains a very small section open, exhibiting beds 4 or 5 feet in thick- 

 ness. Scattered over the surface of the field are many specimens of 

 GrypTicea incurva, and occasional fragments of Ammonites angidatus, 

 A. Bucklandi, and A. Conyheari. Under the hedge, on the western 

 boundary of this field through its greater length, the Lias may be 

 seen, and there will be again found, as the following list will sufii- 

 ciently show, nearly all the ^' Infralias " species of the continent. 

 "With them are present many Gryphcea incurva, and examples of 

 Ammonites BucMandi, A. Conyheari, and A. angidatus ; and, as 

 though no doubt should hereafter arise respecting this fauna, the little 

 Gasteropoda and other remains are to be seen by thousands within 

 the chambers of the Ammonites themselves. Specimens of Ostrea 

 intusstriata are attached to some of the Oy^yphcaoe of this place. Prom 

 the clays of Keynsham I have obtained a microscopic or j'oung form 

 of Montlivaltia, and from Stout's Hill an example of Thecosmilia 

 Michelini, the first example I have recognized out of South Wales*. 



The beds of the Lower Lias above the Ammonites-Bucklandi series 

 in this part of England are very thin and seldom exposed, and soon 

 pass under the marls of the Middle Lias.
