MOLLUSCA. 757 



Volutions of the spire not well preserved in the type specimen, 

 but they are apparently angular at about their mid-height and 

 are marked with nodes similar to those on the periphery of 

 the outer volution. Aperture narrowly subovate, pointed below, 

 more than twice as high as wide. Surface of the shell apparently 

 smooth, or marked only with inconspicuous lines of growth. 



Remarks. This species closely resembles P. holme sianus 

 Gabb, but the nodes upon the shoulder of the outer volution 

 are larger and more elongate, and all spiral markings are 

 lacking. 



Formation and locality. Cliffwood clay, near Matawan 

 (107). 



Geographic distribution. New Jersey.

Description. "Shell of moderate size, about i l / 2 inches in 

 length ; spire short, less than one-third as long as the body volu- 

 tion and beak; volutions four or more, the upper ones rather 

 small and the body volution proportionally large, ventricose in 

 the middle and extended in front in a moderately long, slightly 

 twisted canal ; aperture large, more than half the entire length of 

 the shell ; the outer lip broadly and strongly sinuate in the upper 

 part and somewhat extended forward below ; columella slender, 

 twisted ; surface of the volutions marked by rather strong, promi- 

 nent, vertical folds, which are most distinct on the body of the 

 lower whorl, but become obsolete below, and on the upper whorls 

 are extended from suture to suture, 10 of these folds being 

 visible on the large volution; strong lines of growth also cross 

 the shell parallel to the border of the aperture; closely arranged, 

 elevated spiral lines cover the entire shell, and are finest and most 

 numerous on the upper part, more distant below the middle, and 

 strongly marked on the anterior beak, where they are very oblique 

 the spaces between the lines apparently flat." (Whitfield.)
