GASTEROPODA OF THE EOCENE MARLS. 203 
slender columellar fold replaces the two or three of that shell, and is also 
placed higher on the columella. I know of no other Eocene shell in this 
country which closely resembles this one, especially in its great size and 
robust character, coupled with its form and strongly nodose spire; some of 
the casts are nearly 6 inches in length when deprived of the anterior beak, 
which has been, with the aperture, as long as the entire shell besides. 
Many of the casts which I have observed appear to be nearly or quite des- 
titute of the nodes and would be readily taken for a distinct species. This 
feature, or absence of feature, | presume arises from a thickening of the 
shell on the inside in old examples, filling up the depressions of the nodes 
on the inside of the whorls. 
"Formation and locality: In the upper layer of the Upper Green Marls, 
at Shark River and Farmingdale, New Jersey. I believe it also occurs at 
Monmouth and Squankum, New Jersey. Collections Am. Mus. Nat. His-

FASCIOLARIA PROPINQUA, 0. Sp. 
Plate xxvii, Fig. 3. 
Shell above a medium size, fusiform; spire moderately elevated; beak 
long, proportionally strong, as long as or longer than the spire, measuring 
from the middle of the body whorl; apical angle of the spire less than 45° ; 
volutions about six, rather strong, with moderately marked sutures, the 
upper ones marked by strong vertical nodes, which are obsolete on the 
lower two or two and a half; these latter are rounded or very slightly 
angular, the last one being imperceptible, flattened on the periphery for 
nearly one-third of its height and marked only by transverse lines of 
growth. Aperture moderately large; beak long and the channel narrow; 
columella marked by one single, very slender and very oblique fold, which 
is situated at about the middle of its length when looking directly into the 
aperture of the shell. 
This species is smaller than either of the two associated species. It 
was at first thought to be the young of I’. Hercules, but on critical study I 
find characters revealed which prevent its alliance with that one. It resem- 
bles it particularly in the upper volutions, in their being nodose in the same
