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 duoy 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, pi. 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 



iri the work of Martini, pi. 49, under the name of BUCCINUM 

 maculatum. This shell differs principally from the preceding 

 specimen ,^n 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 pi. I, fig. 2. 



Quoy and Gaimard have given in their valuable work, Voyage 

 de T Astrolabe, pi. 30, fig. 12, the figure of a specimen of this 

 same variety, but without regular transverse points.
