118 FOSSILS OF THE NEIGHBOURHOOD. 



extinct tribes, and subjoin a list of those which have 

 been identified and named. 



The entire range of lime-rock about Plymouth may 

 be stated to contain, in its substance, animal remains ; 

 although they are found in varied quantities, accord- 

 ing to the spot selected for examination ; they are 

 found to be most abundant at the junction of lime- 

 stone with ciay-slate ; in general they are observed 

 to be so disposed, that at one spot specimens of one 

 kind only — Zoophytes — are found ; and at another 

 spot, specimens of another kind — Shells ; — and again, 

 in respect of shells, bivalves and univalves are usually 

 found separate, although occasionally each may be 

 blended with zoophytes. They who are desirous of 

 verifying these remarks, which, while they originated 

 from a pemsal of Mr. Henneh's " Account of the 

 lime-rocks of Plymouth,'' I have had opportunities of 

 corroborating, may visit the following spots, — the 

 East Hoe, Mill Bay Quarry, Ordnance Quarry, 

 Mount Wise, and the Dock Yard : but it must be 

 borne in mind that, although, at these and other 

 places, well defined, and identified specimens can be 

 obtained, and which we shall presently enumerate, 

 there is an immense number of specimens to be seen 

 to which no name can be assigned ; and further, that 

 it has been supposed, and with every probability of 

 truth, that the varied and beautiful colors of our 

 limestone, are in great part owing to the remains of 

 organised beings. I feel quite convinced, from an 

 inspection of specimens of Zoophytic remains, which 

 almost exclusively composed a wall of some size, 

 near Yealmpton, and which I have also obtained 

 from quarries of limestone at Oreston, and other 

 spots, not mentioned by Mr. Henneh, that fossils 

 are continued through the same range from the point 

 where Mr. H. quits its consideration, at Prince Rock, 

 and I am likewise certain that many more kinds 

 than have been enumerated by him do exist : there 

 is one, indeed, which, from its interest and rarity, 

 deserves especial notice — a fossil fish, contained in
