BRITISH CARBONIFEROUS BRACHIOPODA. 



The work in connection with British Carboniferous Brachiopoda must not, however, 

 be supposed exhausted, for there is much still to be learnt and achieved by future 

 observers ; for out of the one hundred and twenty species enumerated in my tables, from 

 fifteen to eighteen have not been sufficiently studied, from want of satisfactory or sufficient 

 material, and these may hereafter prove to be partly or entirely synonyms, varieties, or 

 variations in shape of some of the others ; so that I do not consider that many more 

 than about one hundred good species have been proved to exist in Great Britain. 



Seventy-one British counties have, up to the present time, afforded Carboni- 

 ferous Brachiopoda, and the following numerical statements must be considered to 

 represent the present state of our knowledge, as some counties have been much more 

 searched than others, so that with time these numbers will no doubt be notably modified. 

 It will however be interesting, I think, to record the state of our information up to the 

 early portion of 1862.
