" This shell, as shown by the internal casts, differs from the other 

 species herein described in its more elevated spire and rounded but less 

 gibbous and less ventricose volutions, especially the outer one. The axis 

 has also been much stronger in proportion to the size of the specimen, and 

 the anterior canal shorter and less distinct. The peculiar flattened node- 

 like protuberances on the columellar lip may be the result of accident. 

 Indeed, it would seem almost impossible for the animal to have purposely 

 formed and retained such protuberances, as they are not continuous or 

 connected, but are each one isolated from the others, but their gradual 

 increase in size as the shell has developed is a curious feature and gives 

 them a meaning which they otherwise would not possess. The shell, how- 

 ever, is specifically distinct from the others, entirely independent of this 

 peculiarity." — Whitfield, 1892. 



Type Locality. — Holmdel, New Jersey. 



Weller has united under Pyropsis trochiformis (Tuomey) all of the 

 individuals described by Whitfield under the name of P. reileyi. Most 

 of Whitfield's specimens are casts, but on one of them a surface sculpture 

 has been preserved which is certainly distinct from that which has been 

 associated probably correctly with P. trochiformis. The latter is wound 

 with spiral bands, approximately uniform in size and spacing and more 

 or less undulated by the axials but not nodose. In Whitfield's species the 

 body whorl is sculptured with sharply nodulated spirals alternated with 

 simple lira?. The general contour, however, differs very little from some 

 of the manifestations of P. trochiformis (Tuomey) sensu lato.
