rather a rough exterior. Body whorl contracfted rapidly from 

 the center toward the base. Striae coarser on the ba.sal portion ; 

 spire about one third the length of the shell : apex blunt ; 

 aperture oblong-ovate, smooth within. Columella broadly 

 reflected ; canal produced canaliculate at base. 



''Locality. — Alabama : Hatchetigbee bluff. 



"Differs from the previous species, \C. hatchetigbeensis^ by 

 being striate, its more produced spire and fusiform shape. 



"The outer tip [lip?] is broken away, but the lines of growth 

 indicate a semicircular slit, as in the former species." 



When viewed from the apex, this shell shows quite a 

 prominent broad channel just below the suture. Below there 

 are indications of short, slight ribs or faint spines. The lines 

 of growth in passing from the latitude of faint spines bend to the 

 left as they pass upwards and over the broad channel to the 

 suture. This reminds one of Levifusus and we may well wonder 

 if the canaliculate fulgurs may not have had a similar form 

 for their prototype.

Heilprin' s original descriptioyi. — "Shell somewhat bucciniform ; 

 whorls about eight, sub-angular, the first three or four smooth, 

 the remainder ornamented with both longitudinal costse and 

 revolving striae, the latter showing a tendency to alternate in 

 size ; the costae are arcuate, not in a regular continuous series, 

 those on the body w^horl extending considerably below the middle 

 of the whorl ; aperture about the length of the spire, the canal 

 somewhat refle(5ted ; columella covered with a callous deposit, 

 considerably twisted ; outer lip dentate within.

"This species greatly resembles the Fusiis scalarinus of 

 Deshayes (Coquilles Fossiles, 11, p. 574, pi, lxxiii, figs. 27 and 

 28), but may be distinguished by the le.s.ser prominence of its
