BUCCINUM desertum. 

 TAB. CCCCX\.—fig. 1. 

 Spec. Char. Ovate oblong, costated, trans- 

 versely striated ; whorls contracted above 

 by a rounded canal ; lip striated within. 

 Syn. Buccinum desertum, Brander,/. 15. 



J.N 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.

BUCCINUM canaliculatiim. 

 TAB. CCCCXV.— ^^. 2. 

 Spec. Char. Ovato-elongated, transversely 

 striated; spire costated; whorls separated 

 by a canal ; lip thickened, sharp, dentate- 

 striated within. 

 Syn. Biiccinum desertum, JSrcmder, Jig. 18 

 a7id 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 tlie 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 s])ire of that fossil. 



Very frequent at Muddlford and Barton, as the nu- 

 merous specimens seat by several good Friendt) abuU" 

 daotly prove.
