ieveral genera, and therefore is a fcene of 

 confufion. Davila, who follows and cor- 

 re£ls his method, defines them to have a 

 large oblong aperture, and divides them 

 into four genera ; but the firft genus which 

 he calls whole-mouthed "*, without a tail 

 or gutter, is my genus of Turbo among 

 the Cochleae or Snails, and are not Bucci- 

 na ; for their mouth is perfedlj circum- 

 fcribed or bordered : fuch are the Midas-s 

 Ear, and others ; for thefe Shells, though 

 in fliape and appearance they feem Buccina, 

 yet, their mouth being perfeftly circum- 

 fcribed or bordered, and devoid of gutter 

 or break, ftrongly diftinguifhes them. Lin- 

 naeus defines the Buccina extremely vVell 

 by an oval aperture ending in a gutter ; 

 but his feftions of them are perplexed and 

 vague. The other authors, as Buonannij 

 Ruraphius, Seba, &c. give no charafter for 

 Buccina, but range Shells as fueh, only as 

 their fancy furmifes.
