396 GEOLOGY OF OLD HAMPSHIRE COUNTY, MASS. 



Connecticut in Montague, 2 miles southwest of the latter place, as noticed 

 by E. Hitchcock in 1841. The latter localities are a coarse, gray arkose. 

 I am convinced, from an inspection of European specimens in the museum 

 at Munich, of the identity of this species with C. plaiyphyUa. 



Dr. Newberry cites, also, Westfield, Massachusetts, Durham, Comiecti- 

 cut, and Newark and Milford, in New Jersey. 



Macrot.eniopteris magnifolia Schimper. 

 Small leaves for this species, about 3 inches long, and a little more 

 cordate than the figures. In black shale; Turners Falls. 



Macrot.eniopteris sp.

From a bowlder of dark-gray sandstone on Mount Holyoke. The 



impression is nearly 2 feet long.^ I can not find the specimen in the 



Amherst collection. Similar large leaves occur in the north part of 



Montague, on the road going down to the bridge to Greenfield. 



AsTROCARPus viRGiNiENSis Fontaine. 



A very poorly preserved specimen of a large frond with strong rachis 

 and long, straight pinnae. On buff arkose, like that under Mount Tom, 

 containing Clathropteris. From the collection of President Hitchcock, who 

 said it came from the valley, but could not give the exact locality.
