14 GENUS BUCCINUM. 
varies in its form and coloring, in its different stages. The 
shell which. served for the description of Lamarck, a figure of 
which we give in plate VII, fig. 22, was young; whence the color 
of the aperture presented him only a whitish tint upon the colu- 
mella, and several large brown bands are seen upon the inner 
edge of the lip. 
The specimens brought from New Zealand by Quoy and 
Gaimard are generally much larger, and more colored. One of 
these specimens has served us for the first figure of our first 
plate. Other specimens again, brought by these two learned 
naturalists, offer us a very distinct variety, which is found figur- 
ed in Martini, pl. 7, under the name of Buccinum striatum ; 
this variety is generally more globular. The spire is pointed, 
shorter, and sometimes re-entering ; the upper whirls are often- 
times folded. The callosity at the top of the aperture is thick, 
and strongly prominent. The columella is arched, and slightly 
umbilicated. 
We regard as a variety of this last shell, a species figured also 
in the work of Martini, pl. 49, under the name of Buccinum 
maculatum. 'This shell differs principally from the preceding 
specimen in its size, and in the whirls of the spire which are 
more rounded. The columella is almost straight, smooth, a 
little projecting at its base, which partially covers a pretty -dis- 
tinct umbilicus, encircled by a margin which exists at the base 
of the emargination. We give as this variety pl. I, fig. 2. 
Quoy and Gaimard have given in their valuable work, Voyage 
de l Astrolabe, pl. 30, fig. 12, the figure of a specimen of this 
same variety, but without regular transverse points.
