GUIDE TO LOCALITIES. 



remains in these rocks are the footprints, fishes and plants. The 

 footprints are found in many places. The first described by 

 Hitchcock came from Montague, Gill, Northampton (east side of 

 Mount Tom), and from South Hadley. Numerous localities have 

 been discovered since, Hitchcock giving thirty-eight in his great 

 memoir. The most prolific as well as most important is probably 

 Turner's Falls, and the vicinity of Lily pond. 



Fossil fishes occur plentifully at Turner's Falls, and they have 

 been found also at Chicopee Falls, Amherst, Hadley Falls, Sun- 

 derland, Deerfield and West Springfield, Mass. The Massachu- 

 setts cases belong to the genera Catopteris and Ischypterus, with 

 the exception of the Chicopee Falls specimens, which have been 

 described under the name of Acentrophorus chicopensis Newb. 

 The plants found all seem, according to Newberry, to be floated 

 fragments which sunk and were buried. In Massachusetts they 

 have been found at Turner's Falls, Sunderland and East Hamp- 

 ton, Montague and Mount Holyoke. The following species have 

 been described by Newberry : Schlzoneura planicostata Rogers, 

 Pachyphyllum simile Newb., Clathropteris platyphylla Brong. 

 (=C. rectlusoulus Hitch.). From Mount Holyoke Hitchcock de- 

 scribed Tumiopteris sp., and from Montague several remains of 

 Voltzia? 



The black fish beds of Turner's Falls and Sunderland lie just 

 above the Deerfield trap sheet and the black plant beds of the 

 Holyoke area lie above the Holyoke traps (Emerson).
