BUCCINUM Dalei. 



TAB. CCCCLXXXVL— /gs. 1 and 2. 



Spec. Ch\r, Ovate^ smooth^ or slig-litly sulcated, 

 thick ; whorls very convex above ; apex of the 

 spire obtuse, 

 var. (a) ventricose, rarely sulcated. (^g*. 1.) 

 var. (/3) elongated, more or less sulcated. {Jig. 2.) 



The rounded form of the upper portions of the whorls 

 and obtuse apex are characters that distinguish this Buc- 

 cinum at first sight ; the sulci are numerous and close, 

 but seldom extend to the last whorl ; generally they are 

 only to be discovered near the apex. The beak, from 

 which a ridge winds up the columella, is short, rather 

 wide, and has a more or less recurved edge ; the shell 

 is thick but very rarely, antiquated. 



This very distinct shell was first received from our 

 lamented friend Mrs. Cobbold, in 1812; since which time 

 the Rev. Mr. Leathes has kindly supplied us with a se- 

 ries showing the two varieties : it is named by him 

 B. Dalei, to commemorate the labours of Dale, who ap- 

 pears to have been almost the first person that took no- 

 tice of the Suffolk Cif^ag^ fosgils.
