102 PALEONTOLOGY OF NEW JETtSE^. 



appear somewhat uncommon in the deposits of this period within the State, 

 as only some two or three fragments of it have been found beyond this one 

 specimen, and its name does not appear in many of the lists of Miocene 

 shells of New Jersey. 



Locality: The specimen is from Heislerville, Cumberland County, N. J., 

 and belongs to the collections sent from Rutgers College, New Brunswick, 

 N.J.

" Subfusiform; spire moderate, turreted, sides above the angle oblique; 

 angle subcarinated, with numerous approximate subcompressed tubercles; 

 whorls striated transversely. * * ■ * Allied to B. rugosim, but differs in 

 wanting the channel round the base of the whorls." (Conrad, Phil. Acad. 

 Nat. Sci., 1862, p. 584.) 



I have seen only small and imperfect examples of this shell. It seems 

 to have been somewhat rare over the region of these deposits. The largest 

 fragment which I have seen is but little more than one inch in diameter, and 

 retains three and a half volutions outside of the mamillated nucleus; but it 

 shows the broken ridge of another full volution beyond these, which would 

 have given it a width of probably fully two inches across the spire. The 

 spire is decidedly scalariform, the elevation of the inner above the outer 

 volutions rapidly increasing in the outer whorls, with the sides of the whorl 

 nearly vertical above those outside of it, and the surface marked by very 

 fine distinct spiral lines throughout, which are wavy on the outer surface 

 below the compressed nodes that line the outer angle of the spire. These 

 nodes are at first very small near the nuclear apex of the spire, and increase 

 both in size and distance as the shell increases in size, becoming large and 

 conspicuous on the outer volutions. 



This shell is near B. coronatum Con., but differs in that the volutions of 

 the spire are flat on the top instead of rapidly sloping, and the nodes are
