Description. — "Shell of medium size, elongate ovate or sub- 

 cylindrical in outline, spire moderately elevated, entire length 

 and number of volutions unknown. Body volution cylindrical in 

 the upper half, obtusely rounded below. Aperture narrow, 

 pointed and very contracted above and rounded below, about 

 four-fifths as long as the length of the body volution, measured 

 on the same side. Columella slightly twisted below and marked 

 by a single tooth near the base, as determined by the groove 

 showing on the cast. Surface of the shell marked by fine spii^al 

 lines, the number undeterminable from the specimens examined." 

 (Whitfield.) 



The dimensions of an internal cast incomplete at the apex are : 

 height, 25.5 mm.; if complete, it would doubtless be at least 30 

 mm.; maximum diameter, 11.5 mm.; height of aperture, 18.5 

 mm. 



Remarks. — In the recent collections of the Survey this species 

 has been observed only from the Woodbury clay, although the 

 types of the species are apparently from the Navesink marl. 

 The species differs from A. cretacea in its much more elongate 

 and cylindrical form. It apparently resembles the shell described 

 from Mississippi by Conrad as Solididus lintetis^, but no exam- 

 ples of that species have been available for comparison, so that 

 it cannot be determined whether the two' are identical or not. 



Pormation and locality. — Woodbury clay, Lorillard (102), 

 near Matawan (103) ; Navesink marl (Coll. Phil. Acad. Sci.). 



Geographic distribution. — New Jersey.
