lied, than the Cornets, or Horn SheilSj in ge- 
neral. 
The Shell here represented, is properly the 
Gekroonde Tepel-Bak, of the Dutch ; or 
Nipple Crov/ned Trough or Boat Shell, which 
some call the Gondola ShelL. It receives the 
epithet Crowned, on account of the toothed 
appearance which goes round the first circum- 
volution. It is called a Trough, or Boat, 
because the opening is large, and swelled ; for 
these shells are found from fifteen to sixteen 
inches in length, and nine in circumference. 
Lastly, they call it Boat with a Nipple, in 
Dutch Zizenbak ; because the small contours 
at the extremity resemble the Nipple of a 
Breast. 
This shell is smooth, and brilliant. The 
colour is a rich brown, on which are tv/o 
bands of a darker colour. The entire length 
of the shell is marked with small lines. The 
internal colour is white, bordering on yellow.
