This niollu.<k was described by Conrad in the American Journal 

 of iScience, New Series, vol. II, 1846, p. 397, as follows : " Fususper- 

 rugatus Conrad. ^Manatee River. Fusiform, with remote longitu- 

 dinal ribs, and large prominent revolving lines alternating with a 

 fine line ; whorls longitudinally rugose, upper half flat and oblique ; 

 aperture rather more than half the length of the shell, purple with- 

 in ; labrum striate ; color of the exterior cinereous. Proportionally 

 wider than F. cinereus, with fewer and larger ribs and lines." 



The only references I have been able

 the United States National Museum, p. 

 120, and in the Report on the Blake Gas- 

 teropoda, p. 214, in which he says : " There 

 are three American species known to be- 

 long to it ; ( Urosalpinx) :— U. cinereus Say, 

 ranging from Massachusetts to Florida ; 

 U. tampaensis Conrad, known only from 



"'■ the west coast of Florida lastly 



U. pen'ugatns Conrad." 



Among the sjDecimens of cinereus in 

 the collection of the Academy of Natural 

 Sciences of Philadelphia [ found several trays of perrugatus, and 

 as no really good description, and no figure has been published of 

 this species, I take this opportunity of redescribingand figuring the 

 same. 

 Urosalpinx perrugatus Comail. 



Shell fusiform, solid, cinerous, under the lens show'ing a scabrous 

 texture ; whorls six, subcarinated, longitudinally plicate, the folds 

 eight in number on the last whorl, large, rounded ; there are eigh- 

 teen strong, spiral lirse, with fine intervening threads ; aperture 

 ovate, rather more than half the length of the entire shell ; outer lip 

 rounded, edge scalloped by the spiral lirje ; inner lip arcuate, 

 smooth ; canal longish, open, reflexed ; umbilicus none, but there is
