wards the aperture. Whorls six, angular: slight traces of tubercles may be detected on the 
third, fourth and fifth whorls. Suture deeply channelled. Surface with numerous revolving 
stria, which are also very distinct on the inside of the lip: extremity of the canal rounded, 
subacute; columella sinuous, with two or more folds. Color, varied with rufous and yellowish 
white, with an obsolete yellowish white revolving band. on the body-whorl ; chesnut-color 
within the aperture, with traces of parallel dusky revolving bands. 
Youne. Spire less elevated; the keel distinctly separates the upper from the under portions 
of the body-whorl, without any vestige of tubercles. Outer strie equidistant, distinct and 
subequal ; none on the inside of the lip: columella with a single indistinct fold. Color, light 
yellowish, with vertical sinuous subequidistant rufous lines ; a faint trace of a light revolving 
band. 
Length, four to four and a half inches. 
I have met with this shell in the collections of Dr. Budd and others, but cannot find it 
authenticated as a New-York species. It occurs probably farther south along the coast.
