the deposit, but not umbilicate; surface of the shell marked by 

 proportionately strong, transverse lines of growth, which are 

 exceedingly irregular; and also by fine, even, corrugated spiral 

 lines crossing them." (Whitfield.) 



The dimensions of one of the type specimens are: height, 24 

 mm.; maximum diameter, 14.5 mm.; height of aperture, 14.5 

 mm. The largest individual observed has a height of 27 mm., 

 and many specimens are much smaller than the dimensions of the 

 type given. 



Remarks. This species is a close ally of the western A. palu- 

 dinaeformis, with which it has sometimes been identified, but 

 it is a more robust shell with shorter spire and proportionally 

 larger body volution, which gives it a larger aperture. The sur- 

 face characters of the two species are almost identical, but the 

 New Jersey shell has the revolving lines a little more closely 

 arranged. 



Formation and locality. Merchantville clay-marl, near Mat- 

 awan (101); Woodbury clay, Lorillard (102), near Matawan 

 (103), near Haddonfield (164, 183). 



Geographic distribution. New Jersey.
