Description. Adult shell fig-shaped ; the carina on the body-whorl nearly obsolete to- 

 wards the aperture. WJiorls six, angular : slight traces of tubercles may be detected on the 

 third, fourth and fifth whorls. Suture deeply channelled. Surface with numerous revolving 

 striae, 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. 



Young. Spire less elevated ; the keel distinctly separates the upper from the under portions 

 of the body-whorl, without any vestige of tubercles. Outer stria? 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.
