 standing of our papers on the distribution of these fossils, 

 now about to be published by the Geological Society and 

 the Geologists' Association. 



The descriptions of these species are brief, and the figures 

 in illustration of them are limited, in most cases, to two or 

 three views of each. It is believed, however, that they will 

 suffice for the identification of the species ; and they will cer- 

 tainly help our observations on their distribution. 



In noticing the following species, in many instances we give 

 only a few of their localities ; and this is invariably the case 

 where the species are of common occurrence, as exhaustive
