318 [APRIL, 
F. tuberculatus, Con. Miocene Shells, cover of No. 2, 1839. 
Lvewdity.—Patuxent river, St. Mary’s Co. Maryland. 
Allied to F. fusiformis, but is more ventricose, proportionally shorter. It 
may readily be distinguished by the carina of the volutions, which is very 
strongly marked towards the apex. 
8. Funeur carica. (Pyrula carica Lam.) 
Locality.—North Carolina. Prof. E. Mitchell. 
A large specimen of the variety with short spines, is in the collection of the 
Academy of Natural Sciences. 
9. F. rustrorme. Fusiform, with revolving stria; obsolete, except on the 
inferior half of the body whorl, where they are prominent, wrinkled and alter- 
nated in size; spire elevated; whorls with obtuse little prominent tubercles on 
the angle which is situated near the suture and is obtuse. 
F. fustformis, Con. Miocene Shells, cover of No. 2, 1839. 
Locality.—Patuxent river, St. Mary’s Co., Maryland. 
10. F. maximum. Pyriform, ventricose, moderately thick, with coarse distant 
subimbricated lines of growth; spire short, with revolving strie#; whorls con- 
cave above, rounded inferiorly ; beak long and sinuous; columella very concave; 
aperture patulous. Length 75 inches. 
FE’. maximus, Con., Miocene Shells, cover of No. 2, 1839. 
Locality. Yorktown, Virginia. - 
There is a variety of this shell thick and ponderous ; angle of penultimate and 
body whorls with short distant arched or foliated spines, each of which is con- 
nected with a longitudinal line or fold; lines most prominent towards the base 
where the beak is somewhat tumid. 
This is the largest fossil species known to me, and resembles F.arwanwm, but 
the rounded volutions of the spire is a striking point of difference. 
11. F. incite. Fusiform, with distant coarse, prominent and fine impressed 
revolving lines; body whorl profoundly ventricose, shoulder rounded, summit 
with a broad concave furrow margined by a profound carinated line, between 
which and the suture is a wide profound channel; spire conical, elevated, whorls 
ventricose; aperture dilated. Length 64 inches. 
F. inetlis, Con., Sillim. Journ. vol. xxiii. p. 343. 
Locality. Yorktown, Virginia. 
This large species distantly resembles FP’. cunaliculatum. It is much thicker 
and more ponderous, with a more elevated spire, and with rounded volutions 
destitute of tubercles. 
12. F. conrrarium. Pyriform, sinistral, with wrinkled revolving lines, obso- 
lete on the middle of the large whorl; shoulder obtusely angulated, without 
tubercles; summit of the whorls concave; whorls of the spire angulated in the 
middle, and slightly tuberculated on the angle; beak very long, sinuous; labrum 
with distant prominent lines within. 
F. contrarius, Con., Silliman’s Journ. vol. xxxix. p. 387. 
Locality. Natural Well, Duplin Co., N.C. 
A much smaller species than F’. perversum, differing in its want of tubercles 
on the shoulder when adult, (for young shells have small tubercles, not com- 
pressed as in the kindred species.) The shell is proportionally thicker, the 
columella more concave and,the angle more prominent. 
13. F. excavartum. Pyriform, with revolving lines, very prominent on the 
inferior half of the large whorl; shoulder with a wide concave depression; 
spire widely and profoundly channelled, the whorls bicarinated and slightly 
tuberculated on the carine. 
F. excavatus, Con., Sillim. Journ. xxxix. p. 387. 
Locality. Natural Well, Duplin Co. N.C. 
14. F. Oreconense. Fusiform with unequal prominent revolving lines, a few 
of which are considerably larger than the others, on the upper portion of the 
body whorl: they are also coarser towards the base, and attenuated in size;
