of their natural affinities ; accompanied by references to their place in 
the scale of stratification. As a considerable portion of the fossils herein 
mentioned have not been previously described or figured, it has become 
necessary to assign names to them. In the execution of this duty, 
manuscript names, when attainable, have been generally adopted, and, 
instead of specific characters, a figure, of the natural size, or in the 
proportion expressed by the contiguous fractions, is given to illustrate 
every new species. New figures have sometimes been added of fossils 
but little known, highly important, or not before represented with proper 
fidelity ; but this has been seldom judged necessary with respect to 
common species, for which a reference will be found to some generally 
known and accessible work on the subject.
