species ; they certainly represent it very well as it appears in the 
young state. 
I think it highly probable that this is the Bulla Ficus, Var. h. 
GrmeL, which Dillwyn describes under the name of Bulla pyrum, 
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 striae, which are alternately larger, crossed by smaller 
striae. 
Length four inches and one-tenth. Glreatest breadth two inches 
and one-fifth nearly. Inhabits the coast of Greorgia and East 
Florida. Cabinet of the Academy. 
This species has been hitherto confounded with P. Jicus, to 
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 ; 
spire acute ; labium incrassated, yellowish-brown ; labrum within 
white and thick, at the edge thin, and lineated with dark brown- 
ish ; throat white 3 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 Maryland, 
and oh the coast of Carolina, Greorgia 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- 
ly indented ; color pale reddish-brown, immaculate.
