Locality 187 A.—A second locality in the Green Pond region which 
has furnished fossils from the Decker Ferry formation is in an 
abandoned quarry at Upper Longwood, and the following species 
have been identified: 
1. Monotrypa corrugata n. sp. 
2. Stropheodonta bipartita (Hall). 
3. Chonetes jerseyensis Weller. 
4. Orthis flabellites Foerste. 
5. Rhynchonella deckerensis n. sp. 
6. Rhynchonella agglomerata n. sp. 
Atrypa reticularis (Linn.). 
The Cane at both of these Green Pond localities are typical of the 
lower or Chonetes jerseyensis zone of the Decker Ferry formation, 
and the higher faunas have not been anywhere detected in the region. 
The only species of the fauna in the Green Pond region which does 
not occur in the Chonetes jerseyensis zone of the Delaware valley is 
Orthis flabellites, which, in the latter region, has been found only 
in the red limestone bed associated with the Ptilodictya frondosa 
fauna.

Correlation of the Decker Ferry Faunas. 
The following complete list of recognized species in all the faunal 
zones of the Decker Ferry formation will serve as a means of com- 
parison with other faunas of Silurian age in America and elsewhere: 
1. Diphyphyllum integumentum Barrett. 
2. Prismatophyllum inequalis (Hall). 
3. Favosites corrugatus n. sp. 
4. Favosites pyriformis (Hall). 
5. Cladopora rectilineata n. sp. 
6. Halysites catenularia (Linn.). 
Monotrypa corrugata n. sp.
