cape its enemies. The Cuttle fish is an ugly looking, and 

 soraetimes a formidable creature. It is provided with arms, 

 which are arranged around its mouth, covered with power- 

 fiil suckers and horny hooks ; with these it firmly lays 

 hold of, and endeavours to secure, its prey. In the Indian 

 seas it attalns considerable size, and an instance is recorded 

 of its climbing up the side of a boat, and fastening itself 

 upon one of its occupants, who could only be released by 

 cutting off the arms of his formidable antagonist. It is 

 from these the sepia used for painting is prepared. In a 

 nodule I have opened, there is the ink bag of a Cuttle Fish 

 with its ink perfectly preserved, which, with a little trouble, 

 would be ready for use. 



In the bed whose contents have so far formed the subject 

 of my paper, there have not yet been found any traces of 

 the Pterodactyle, a flying reptile, the remains of which have 

 been found in the Lower Lias, and more frequently in the 

 Oolite and chalk above, nor are there any traces of birds, 

 although during the deposition of the New Red Sandstone, 

 if we niay judge by the impressions of footsteps, left in 

 numerous instances when it must have been in the State of 

 a soft mud, they must have abounded. But what is remark- 

 able, none of their bones have ever been found in it. 

 Another important class is wanting ; viz : Mammalia, 

 the first remains of which are found in the Stonesfield 

 Slate above. I do not despair that these may some day be 

 found to have their representatives in the Upper Lias. 



Leaving this bed of Yellow Limestone, we will shortly 

 consider the organic remains that are to be found in other 

 portions of the sei'ies. In the Maristone, are several species 

 of Ammonites and NautUi, but they are more frequent in 

 the beds of the Upper Lias, where thousands are to be 

 found. One species, and the most abundant, is Ammonites
