GASTEROPODA OF THE LOWER GREEN MARLS. 95 
TURRICULA SCALARIFORMIS, ll. Sp. 
Plate x1, Fig. 4. 
Shell greatly elongated, the spire being proportionally slender and 
composed of numerous volutions, which are moderately convex, and mod- 
erately increasing in height with additional growth; number unknown; 
the specimen consists only of a portion of the spire containing about five 
volutions, the apex and body volution being absent; surface marked by 
strong vertical folds which are separated by concave, equally wide depres- 
sions, quite straight and ridged in their direction from suture to suture, and 
number about sixteen to each volution; folds crossed by spiral lines, about 
eight of which can be counted on the exposed part of the volutions, and 
raised and rounded on the top. 
This species differs from the others of the genus in the New Jersey 
Green Sands in its more rounded volutious; in the stronger vertical folds, 
which are not flexuous between the sutures of the volutions and im the 
existence of the spiral lines. In the character of the folds and spiral lines 
the specimen presents something of the appearance ‘ot a Scalaria, but the 
ceneral features are those of a Mitra. The specimen is extremely imper- 
fect, and only that it is desirable to include in the work all the species 
known in the marls, it would not have been made use of. 
Formation and locality: In the dark green marls of the Lower Green 
Sand at Holmdel, New Jersey. From the collection of Rev. Mr. Reiley.

Shell small, slender or elongate-fusiform, with an elevated spire com- 
posed of moderately convex volutions, which may have been, as the author 
says, six in number; sutures quite distinct; body volution proportionally 
large, forming considerably more than halt the length of the shell; aper-
