110 NOTICES OF THE NEWER PLIOCENE DEPOSIT 



nage to Gallochin, an extent of about eight miles bears 

 unequivocal marks of having been elevated, at no very re- 

 mote period. A considerable portion of this coast con- 

 sists of pretty steep rocks, the summits of which are ele- 

 vated 300 or 400 feet above the level of the sea. These 

 rocks show clearly that they have at no very remote period 

 been washed by the sea, at a height certainly more than 

 30 feet above the present high water mark." On the 

 west coast of the county of Inverness, Glengarry informs 

 me that he observes the ancient cliffs and terraces abound- 

 ing with sea shells ; and at Lochalsh, in the same county, 

 a sub-marine forest has been observed.* 



Similar indications of change of level are to be met with 

 in the islands. At Ballaugh, in the Isle of Man, Mr 

 Forbes found them in beds of gravel and sea-sand several 

 feet below the surface, but a greater number above the 

 level of the sea, and from one to two miles inland. These 

 contain sea-shells, bleached, but often tolerably perfect. 

 They all appear to belong to the present era, with the ex- 

 ception of a Nassa allied to the N. macula, but with the 

 spine less produced, the body short, much more ventri- 

 cose, and the longitudinal ribs fewer. It is named in the 

 catalogue N. Monensis. I have already noticed the occur- 

 rence of elevated marine deposits in Bute and Cumbra. 

 I have also observed them in Arran and Inchmarnoch. 

 In the Geological Transactionst Captain Vetch gives an 

 account of sea- worn terraces in the Island of Jura. I am 

 indebted to the Rev. Mr Cameron of Kilchoman for the 

 following account of similar phenomena in Islay. " A 

 large extent of surface has been added to this island, in
