246 BRITISH CARBONIFEROUS BRACHIOPODA. 



We will now mention some of the localities where Carboniferous species have been 

 found, and class them by- counties for convenience, commencing by those of 



ENGLAND. 



In England eighteen counties have afforded about 112 species, and is therefore 

 richer in this respect than Wales, Scotland, or Ireland. By far the larger number of 

 species are derived from the Carboniferous Limestone (Lower Scar Limestone, and its 

 accompanying shales); the Yoredale rocks, Millstone-grit and Coal Formation having 

 offered a much smaller proportion. Carboniferous Brachiopoda have been noticed in 

 England as early as 1685-1692.; for several recognisable species will be found in Listers' 

 ' Historia Sive Synopsis Methodica Conchyliorum et Tubularum Marinarum,' vol. iv, in fob, 

 cum tab ceneis ; but it was not until 1809 that they were seriously collected or studied, 

 and in p. 7 of the present monograph, as well as in the body of the work, references to 

 those authors who have published upon the subject will be found.
