illustrated by 27 plates of very good figures; some of the specs — 
are new, but most of them have already been described; the 
described are not offered as a complete representation of the fauna 
of the several geological horizons of the State, but only as a few | 
the more prominent known species, together with some of the most i 
characteristic new ones of the several localities from which th 
have been obtained; the volume also contains a general list of the 
fossils recognized within the State, including those described, 
showing the formation in which they occur, which arethe Pota
