From the lists given it is evident tliat tlie fauna of the Naples 
beds is the reapparition under more favorable conditions, of the 
assemblage appearing first in the St3*liola layer of the G-enesee 
shales. The important characteristics of the fauna as a whole, are 
1) the prevalence and variet}- of goniatites; 
2) the great numerical development of Cardiola retrostriata ; 
3) the abundance and variety of species of the genus Lunnli- 
cardium. 
4) the frequent occurrence of certain species of coniferous 
woods. 
It is hardly necessar}- in this place to enter into an elaborate 
comparison of the Naples fauna with the various developments of 
the Intumescens or Gouiatiten-kalk fauna in the old world, in 
Devonshire, Brittan}-, Belgium, Westphalia, the Hartz, the St}-- 
rian and Carinthian Alps, the Urals, etc. With all these occur- 
rences there will be found man}- features in common, and it ma}' 
be assumed that the student of palaeozoic faunas is more or less 
familiar with the published discussions of these faunas. 
In the Naples fauna there is a noteworth}- feature in the total 
absence of trilobitic remains which are usuall}- present, though 
not abundant in its transatlantic manifestations; and in the pres- 
ence of phyllocarid crustaceans, which are not elsewhere known 
at this horizon. On the other hand not onl}' the predominant 
elements of the fauna but the generic association throughout, and 
the expression of the component species, is in precise harmon}-
