ROSTEILITES ANGULATUS, n. Sp. 



Plate XI, 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 jDrobably 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 

 othei's from each other; surface features unknown. 



Somewhat resembles R. nasutus Gabl), 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 B. nastitus 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 Ac^d. Nat. Sci., Phila., with specimens of B. nasutns, 

 B. angulatas, and othex's, but with no more definite locality than "N. J.," 

 so that its locality is not certain.
