88 PALEONTOLOGY OF NEW JERSEY. 
ROSTELLITES ANGULATUS, n. sp. 
Plate x1, Figs. 3, 4. 
Shell moderately large and proportionally slender, with an elevated spire, 
as shown by the cast, the only condition in which it has been recognized; 
body volution forming the great bulk of the shell, and the aperture equaling 
more than one-half of the entire length; volutions probably five or more, 
flattened on their surfaces with abrupt scalariform sutures; last volution 
flattened or obscurely concave below the suture for nearly one-half the 
length, and abruptly contracted below, forming an undefined angle a little 
above the middle of the length of the volution, and extended below into a 
more or less slender columella; aperture narrow and pointed above, broad 
and somewhat effuse below; columella marked by four strong oblique folds, 
the lower one of which is more distant from the next above than are the 
others from each other; surface features unknown. 
Somewhat resembles R. nasutus Gabb, but is rather more robust, with 
a longer aperture, which is expanded at the base, strongly reminding one of 
the aperture of the broad common variety of Volutella angulata Swain, from 
the South American coast, which it much resembles in other respects. The 
volutions as seen in the casts are also flatter on their outer surfaces and have 
a more decided shoulder than on any specimen of R. nasutus which I have 
seen. 
Formation and locality: In the Lower Marl Beds of New Jersey. The 
figured example, which is the most perfect one observed, was associated in 
the collection of the Acad. Nat. Sci., Phila., with specimens of R. nasutus, 
R. angulatus, and others, but with no more definite locality than “N. J.,” 
so that its locality is not certain.
