BUCCINUM desertum. 
TAB. CCCCXV — fig. 1. 
Spec. Char. Ovate oblong, costated, trans- 
versely striated ; whorls contracted above 
by a rounded canal ; lip striated within. 
Syn. Buccinum desertum, Brander, f. 15. 
In general the costse are very irregular, they are nume- 
rous but not very prominent, and have several sharpish 
points upon their upper extremities, where they are 
crossed by the striae ; the upper part of each whorl is 
contracted by such a furrow as might be produced by 
tying a cord round it at a small distance from where it 
joins the spire ; there is an obscure fold, at the base of 
the columella. 
From Barton Cliff by favour of Miss Dent, and the 
Rev. T. Cooke. 
BUCCINUM canaliculatum. 
TAB. CCCCXY.— -fig. 2. 
Spec. Char. Ovato-elongated, transversely 
striated ; spire costated ; whorls separated 
by a canal; lip thickened, sharp, dentate- 
striated within. 
Syn. Buccinum desertum, Brander , fig, 18 
and 19? 
About twice as long as wide, but variable in its pro- 
portions ; the canal around the spire is flat, with an 
elevated margin, and quite different from the canal in 
B. desertum . two or three of the last whorls are mostly 
free from costae, but they have sometimes one or two 
that appear to be formed from a thickening of the lip 
at certain periods of growth ; the beak is curved, the 
columella has no plait. 
That this is the B. desertum of Brander, fig. 18, there 
appears but little doubt, although his figure is too short 
for the more common specimens. The thickened lip, 
and the consequent formation of two or three obscure 
varices upon the latter whorls, do not occur upon B. 
desertum just described : they tend to remove it from 
the same genus, but they are obscure and smooth ; it 
resembles Murex striatulum of Lamarck, but there is no 
canal described about the spire of that fossil. 
Very frequent at Muddiford and Barton, as the nu- 
merous specimens sent by several good Friends abun- 
dantly prove.
