INTRODUCTORY.

Doctor Fleming's collections, and he notices that certain species belong to 

 genera hitherto only found in the secondary formations and principally in 

 the lower groups of that great period. The Ceratites in particular are 

 remarkable, all being new to science, and but for this, serious doubts 

 might have been entertained relative to their geological position, though 

 Dr. Fleming had ascertained by personal examination that they occurred 

 in the same beds as those which contained carboniferous Producti and 

 Spirifera. The author remarks, however, that the rock containing the 

 Ceratites was without any traces of these other palseozoic genera. The 

 fossils which he had for determination included forty-nine species, five of 

 which were in bad preservation and undeterminable. Those described, 

 thirty-six of which are figured, are as follows : —
