6S UNIVALVES BUCCINUM. 



It is perhaps worthy of remark, that the Buccinum Galea 

 has been known to attain the size of a man's liead. 



The species nearest alhed to the Tuns, are the Hehnets, 

 but they are distinguished from them by having their 

 two Hps (with few exceptions) beset with a number of 

 strong and articulate teeth; at the same time having their 

 outsides covered with strong and prominent protuberances 

 or knobs. Among the species of this description may be 

 enumerated the three following, viz. Buccinum Plicatum or 

 Plaited Helmet, Buccinum Cornutum or Horned Helmet 

 and Buccinum Rufum or Bull's-mouth, which is easily 

 distinguishable by its nodulous or knotty belts and the 

 fiery-red glow of its mouth. 



There are also other well known Helmets, as the Draft 

 Board, Zebra, Pin-cushion, and Peacock species; the two 

 latter of which are considered rare. However, one of 

 the rarest species of the Buccina is to be met with in 

 that division of the genus which contains the sort of shells 

 usually called Harps, of which there are several exceed- 

 ingly beautiful and elegant varieties: the principal of 

 which are the Tortoise-shell, David's, Bleeding, Painted, 

 and Many-ridged Harps; the latter of which is the Bucci- 

 num Costatum of Linnaeus, but is more generally known 

 as the Many-ridged Harp ; it surpasses all other varieties 

 in point of elegance and scarcity, and of course is sought 

 after with great avidity by the collector. It is from the 

 Isle of France, and has been sold for as large a sum as 

 fifty pounds. 



Among the other species of Buccina, the Scoops may be 

 considered of some importance. The most usual species 

 are the Buccinum Patulum (the Common or wide-mouth- 

 ed Scoop), Buccinum Monodon (the Unicorn Scoop), and 

 Buccinum Pcrsicum (the Necklace), of which there are
