Heilprin' s original description. — " Ventricose; whorls about 

 nine, the body whorl nodulated on the most convex portion 

 (nearly central), the nodulations consisting of a single series of 

 sharp, obtusely pointed, and flattened spines or nodes, which 

 frequently appear double by the crossing of an impressed line 

 over their basal portion; upper volutions with a similar series of 

 nodes almost immediately above the sutural line, and gradually 

 dwindling off into a crenulation, upper surface of the whorls 

 concave, faintly striated, the sinual rugse indicating but a faint 

 sinus; lower surface with numerous well developed revolving 

 lines, which show a tendency to alternate. Aperture exceeding 

 the spire in length, considerably contracted at about its center.

The generic position of this species has for some time been a 

 matter of perplexity to the writer. Now, however, its generic if 

 not specific identity with Aldrich's Levifusus suteri can be proven 

 by our ample collection of pagodaASks: forms. The Matthews' 

 Ivanding specimens often have somewhat higher spires than those 

 do from Oak Hill; one of the latter is shown by our figure. At 

 Bell's Ivanding, the two forms, suteri and pagoda, both varying 

 somewhat from the Matthews' Landing specimens, are found in 

 the same bed. The Wood's Bluff specimens when young have 

 a decided Surcula-X-{k.^ aspect owing to the height of their spires, 

 but when adult the large size of the body whorl gives them a 

 still greater likeness to FulgurAS)^^ genera. The many interme- 

 diate forms between suteri and pagoda can be more properly dis- 

 cussed in our next year's work, and hence the matter will be
