casts showing no indication of vertical folds or revolving lines." 

 (Whitfield.) 



Remarks. This species may be recognized by its low spire, 

 as compared with T. elevata. The two species are closely allied, 

 and it is possible that this is really only an immature form of that 

 species. 



Formation and locality. Navesink marl, Atlantic Highlands 

 (108), Crosswicks Creek (149). 



Geographic distribution. New Jersey.

Description. The dimensions of the type specimen are: height, 

 with the spire incomplete, 27.5 -mm.; probable total height, 32 

 mm. ; maximum diameter, 23 mm. Volutions large, heavy and 

 massive, strongly rounded on the surface, and probably about 

 five in number; spire short, the apical angle having been about 

 60, making the height of the spire above the top of the body 

 volution, when measured on the back of the shell, about equal to 

 the length of the body volution from that point downward ; aper- 

 ture obliquely elliptical-ovate, as in other species of the genus; 

 columellar cavity in the cast very large, the lower edge being 

 raised above the general surface, indicating a notch or groove at 

 the base of the aperture in the shell, with a rounded callosity 

 above it, forming or representing the tooth or fold on the colu- 

 mellar. 



Remarks. Whitfield evidently had two different shells before 

 him when he described this species. The larger specimen which 

 he has illustrated resembles those large casts which he described 

 under several different names, and which are all referred to 

 Anchura abrupta in this report. The smaller specimen only is 

 here considered as typical of the species. It is by no means cer-
