EMBOSSED HORN. 
the shield which covers the aperture has the 
appearance of the Moon when at full. Thei 
coioua- of the shell is a rich and glowing red;! 
which, after the first and last spiral tui ns, or 
whirls, borders on yellow, and diffuses vast: 
lustre. The first, or chief whirl, is of consi- 
derable magnitude, and bellies, or proje6ls, 
to a great extent : it is surrounded by large 
bumps, or knobs, which are rayed with black 
and white; and glov/ brilliantly with change- 
able colours, like raother-of-pearl. There are, ! 
as it were, three regular rows on this q^rand 
whirl, which frequently contains more than 
forty of these beautiful embossed knobs. The ; 
shell is internally mother-of-pearl ; and, be- 
ing externally covered by a coloured skin,i 
these knobs do not appear so brilliant till they- 
have worn away the skin. The next whirl, i 
which is of a very inferior size, has three 
similar rows of small knobs on a black ground. 
The last whirl, or spire, is vellow ; and it is 
cfowned by a dome, in the centre of which 
rises an obtuse point, or small butron. From 
the side of the circular aperture, or mouth of 
the shell, the grand spiral turn dwindles into 
three small divisions.
