species ; they certainly rcpreseut it very well as it appears in the 

 young state. 



I think it highly probahle that this is the Bulla Ficus, Var. b. 

 Gmel., which Dillwyu describes under the name of Bulla jyyrvm, 

 with the country of which he was unacquainted. 



Pyrula papyratia. — Shell inflated, thin, white, with small, 

 • pale, rufous spots, within pale, dull purplish-red ; whirls with nu- 

 merous spiral strias, which are alternately larger, crossed by smaller 

 striae. 



Length four inches and one-tenth. Greatest breadth two inches 

 and one-fifth nearly. Inhabits the coast of Georgia and East 

 Florida. Cabinet of the Academy. 



This species has been hitherto confounded with P. ficus, U) 

 which indeed it is closely allied, but differs in having the beak 

 proportionably longer, and in being but slightly spotted. 



It is also an inhabitant of the West Indies. 



Turbo irroratus. — Shell thick, greenish or pale cinereous, 

 with numerous revolving, elevated, obtuse, equal lines, which are 

 spotted with abbreviated brownish lines ; suture not indented 5 

 spire acute ; labium incrassated, yellowish-brown ; labriim within 

 white and thick, at the edge thin, and lineated with dark brown- 

 ish ; throat white ; columella with an indentation ; operculum 

 coriaceous. 



Length four-fifths of an inch. Inhabits the coast of the United 

 States. Cabinet of the Academy and Philadelphia Museum. 



This has the general appearance of T. littoreus, but is sufficiently 

 distinct by the above characters ; the calcareous deposit on the 

 labium is copious. 



An inhabitant of our estuaries of the Middle and Southern 

 States. I have found them on the Eastern shore of IMaryland, 

 and on the coast of Carolina, Georgia and Florida ; and my brother 

 obtained a specimen on the coast of New Jersey, of the length of 

 one inch and one-tenth nearly. Mr. Cuvier would place this shell 

 in the genus Paludina. 



Turbo canaliculatus. — Shell thin, globular, with about four 

 volutions ; body whirl with four profound striated grooves, and 

 and several smaller ones near the base and suture ; suture profound-
