Company) H 422 (Plate XN VIII) is similar to that of the 
Magothy River type. 
Martha's Vineyard Amber 
Amber from Gay Head, Martha’s Vineyard, Massa- 
chusetts, was collected by Clifford Kay, United States 
Geological Survey, Boston, Massachusetts. It had been 
reported previously from this locality by Finch (1824). 
Only a few small specimens have been found in a dark 
gray silt rich in fine plant debris, including seeds, cones, 
needles, leaf fragments and a variety of plant tissue ex- 
cellently preserved (Kay, pers. comm., 1966). Unfor- 
tunately ,these remains have not as yet been identified. 
Palynological evidence from these beds (J. Doyle, pers. 
comm., 1967) indicates their belonging to the Upper 
Raritan or Lower Magothy Formations. 
The spectrum (H 111, Plate X XI) is quite distinctive 
from any of the other ambers from Cretaceous strata. 
The intensity of absorption in the carbon-oxygen single 
bond region (8-10) may indicate a higher percentage of 
carbohydrates (as in a gum-resin). he presence of a dis- 
tinct absorption peak at 11.84 (885 cm-!) is also notable. 
Amber from Other Atlantic Coastal Plain Localities 
Amber was obtained from six other localities along 
the Atlantic Coastal Plain. Stratigraphic data for these 
localities are unknown to the authors. It is assumed, 
however, that the amber most likely occurs in Raritan 
or Magothy beds. 
Three spectra of ** Ambrosine’’ from Charleston, South 
Carolina (USNM collection R7317), were made. The 
spectral type represented by H 210 (Plate XVII) is 
typical of that of Baltic Succinite (Beck et al., 1964; 
1966; Langenheim and Beck, 1965). Shepard (1870) 
suggested that this amber originated from conifers from
