Q72 NEW FOSSIL SHELLS 
by faint continuations of the strie, not entirely obliterated by a thin deposite of callus. 
The canal is longer than is usual with the Buccina, and is bent somewhat backwards. 
The columella is much twisted. Close to the upper suture the whorls are bent, first at a 
right angle, and then downwards, descending gradually to the suture. Near the middle 
of the whorl, the strie are faintest. As my only specimen is quite imperfect, I am 
unable to give the length or number of whorls; of these latter, portions of three remain, 
and there have probably been three or four more. 
This fine shell is the largest of our fossil Buccina. Judging from description, it may 
bear a distant resemblance to the B. multirugatum, Conrad, but it differs in its straight 
strie, size, want of an umbilicus, &c, It is quite rare. Mr. Tuomey whose name I 
have great pleasure in affixing to it, tells me that he has met with but two specimens of 
it, both imperfect. 
B. pusittum, Pu. 37. Fic. 98. 
B. testé ovata, sub-conicd, crassd, sub-perforatd, levi; spird ovatd, brevi, obtusd; suturis parvis, linearibus; anfrac- 
tibus quinque, sub-convexis ; anfractu ultimo rotundato; basi levi; perforatione minima; aperturd ovata; columella 
recta. 
Shell ovate, somewhat conical, thick, sub-perforate, smooth; spire ovate, short, obtuse; sutures small, linear; whorls 
five, slightly convex ; last whorl rounded; base smooth; perforation very small; mouth ovate; columella straight. 
Length .08. Breadth .04 of an inch. 
Remarks.—This little shell bears a strong affinity to the recent B. lunatum, Say, but 
it is less ovate, and hardly a fifth the size of that shell. 
B. rrumentum, Pu. 37. Fic. 99. 
B. testa ovato-fusiformi, acuminata, crassa, perforata, levi; spird conicd, elevatd, obtusd; suturis parvis, linearibus; 
onfractibus quinque, convexis; anfractu ultimo rotundato, prope aperturam sub-undulato; basi levi; perforatione 
parva; aperturé acuminato ovatd; canale brevi, obliquo; columelld tortd. 
Shell ovately fusiform, acuminate, thick, perforate, smooth; spire conical, elevated, obtuse; sutures small, linear ; 
whorls five, convex; last whorl rounded, slightly undulate near the mouth; base smooth; perforation small; mouth 
acuminate-ovate; canal short, oblique; columella twisted. 
Length .15. Breadth .10 of an inch. 
Remarks.—The undulations on the last whorl near the aperture are scarcely visible, 
and may be accidental. 
This little shell has no very peculiar characteristics, but I cannot refer it to any 
described species. 
B. quapruLatum, Pur. 37. Fie. 100. 
B. testa ovato-conied, crassd, imperforatd, sulcatd, costatd; spird conicd, sub-elevatd, obtusd, prope apicem lavi et polita; 
suturis parvis, flecuosis; anfractibus sex, valde convexis, prope sutwram superiorem pene levibus; sulcis longitudinalibus, latis, 
profundis; costis transversis, parvis, quadrangularibus, planulatis; anfractw ultimo rotundato; basi costaté; aperturd pene 
ellipticd; columella curvatd, truncatd, inferné plicd parva; canale obliquo. 
Shell ovately conical, thick, imperforate, suleate, costate; spire conical, somewhat elevated, obtuse, smooth and 
polished near the apex; sutures small, flexuose; whorls six, very convex, nearly smooth at the upper suture; sulci 
longitudinal, wide, deep; cost# transverse, small, quadrangular, flattened; last whorl rounded; base costate ; mouth 
nearly elliptical; columella curved, truncate, with a small fold below; canal oblique. 
Length .20. Breadth .12 of an inch. 
Remarks.—The sulcations are unusually wide and close together, rendering the ele- 
vations between them acute. The ribs are four in number on the upper whorls, be-
