" which after being rolled about in the Rhcetic sea, had been re-deposited as 

 " before mentioned. I told Tomes he would see some strange liassic beds 

 " in this district, and he has not been disappointed." As regards myself, 

 a reference to my paper will show that I had not carried the Zone of 

 G. incurva as a shell of the British Lias, in its typical form, so far as the 

 information of Mr. Tomes subsequently induced me. There is an aspect 

 about the shell figured, which, with others in my possession, separates 

 it by certaiu characters, as well of the shell itself, as of its matrix, from 

 the ordinary form of the species to which I have assigned it; which 

 suggests the question, " Was the oyster, (a constantly attacMd shell,) the 

 only derived species found in the beds in question?" 



Under any circumstances, my position is in no way affected, except 

 that I may be called upon to reduce the amplitude of my outline or the 

 breadth of my shade. I remain

 My dear Sir, 



I have written and forwarded the following to you in the hope, and I 

 think I may say in the belief, that it may be found worthy of a place in 

 the proceedings of your Club. I am anxious for its insertion, because it 

 will explain some apparent inaccuracies in a communication which T made 

 to your talented member, Mr. Jones, which was quoted by him in his 

 paper on the Gryphites. I refer more especially to a statement which I 

 made to him respectijig the appearance of the Gryphite near the 

 bottom of the lower lias at Bridgend. This statement attracted the 

 attention of our mutual friend, Mr. Mooke, who entertained opinions 

 differing materially from mine. A correspondence ensued between Mr. 

 MooRE, Mr. Jones, and myself, which ended in a re-investigation of the 

 subject, the results of which I propose to lay before you. But I may as 

 well proceed in chronological order. 



My first acquaintance with the South Wales lias dates from I860, 

 when I visited Bridgend for the purpose of examining the section there, 

 having been stimulated to do so by my friend, Mr. Etheridge. He had 

 told me that a very remarkable section was exposed in the Railway 

 cutting near that town, and I visited the spot in consequence of his 

 information, and in the company of my usual field companion, Mr. 

 KiRSHAW. We spent many hours there, seeking diligently for evidences 

 of the several stages of extinct life, with which we were well acquainted
