specimens; suture impressed, linear; outer lip internally denticu- 

 lated and thickened; inner lip bearing a fold near base of aper- 

 ture; canal long, nearly straight, slightly tortuous, bent upwards, 

 finely striated to the extremity. 



''Localities. — Matthews' and Gregg's Landings, Ala." 

 That this belongs to the Tritons is shown by a specimen in the 

 writer's private collection from Gregg's lyanding, better preserved 

 about its aperture than any figured by Aldrich. 



This species reminds one somewhat of Rhinocantha and Haus- 

 tellum among the Muricidce, but its agreement with certain 

 species of the living Raritdaria^ i. e., Gutturiiium Klein, is closer 

 still.

Conrad's original description. — "Fusiform; whorls eight, an- 

 gular, periphery of angle acute, situated below the middle of 

 the whorl; whorls of spire costate longitudinally, but not very 

 distinctly; revolving lines closely arranged, fine, with a few dis- 

 tant, prominent lines; three first whorls of the spire smooth, the 

 next two tuberculated; angle tuberculated ; a prominent, acute 

 line on the body whorl runs from the upper extremity of the 

 aperture, and a similar finer line between it and the angle 

 above; columella rugose, with a prominent fold near its upper 

 end; labrum dentate within. 



' ' Length i ^ inches. ' ' 



Conrad gives no definite locality for this specimen. He makes 

 the general remark that this and other shells described in the 

 same article are "from a locality farther north in Alabama than 

 Mr. Tuomey had explored."
