ancient colonists of Greece. But according to actual knowledge, 

 and any positive records of zoology, the Serpent, between 10 and 12 

 feet in length, from the tertiary deposits of Salonica, must be deemed 

 an extinct species. The fossil may be provisionally indicated as 

 Laophis crotalo'ides^ .

 Cambrian Rocks of the LoNGMYNDf . No. 2. By J. W. 

 Salter, Esq., F.G.S., and of the Geological Survey. 



[Plate V.] 



In a former communication (March 1856) I described a few obscure 

 traces of animals from these old rocks in the Longmynd, and have 

 now to add some further information, gathered during the last summer 

 in the same locality. 



The markings which were in that paper referred to the burrows 

 of Annelides have been found in the greatest profusion, and through 

 a much greater thickness of strata than before, not less than a mile 

 in vertical measure ; and they have been detected too in places con- 

 siderably to the south and west of the localities before given. 



I am glad of the opportunity of again drawing attention to the 

 subject, partly because the woodcut-section in the former paper, at 

 page 247, Journ. No. 47, was accidentally made so as to exclude the 

 most important beds, and partly because these annelide-markings 

 have, during the present year, been sedulously searched for, and 

 similar ones found, by my friend. Dr. J. E,. Kinahan, of Dublin, in 

 the undoubted Cambrian beds of Bray Head, Wicklow. His paper
