This shell appears by the figures to be about twenty-two lines 

 long and thirteen broad, of a straw colour, with reddish brown 

 transverse ribs, and minute longitudinal striae ; the outer 

 lip is double and toothed, and the inner lip crenulated ; it a 

 good deal resembles Buccinum caudatum, but the aperture 

 ends in rather a narrow beak nearly half an inch long. 



ARUANUS. 84. Shell ventricose, with the spire con- 

 nical and coronated with spines ; aperture 

 dilated, with the beak long, and the pillar 

 flexuous.

 Chemnitz's figure is five and a quarter inches long, of which 

 the beak occupies two inches, and the breadth is about two 

 inches ; it is coarse and ponderous, and slightly ribbed trans- 

 versely ; Linnaeus says that the pillar is flexuous like the let- 

 ter S, and that the colour is a remarkable brownish blue, or 

 sometimes whitish flesh-colour. M. Aruanus of Born ap- 

 pears to be M.fornicatus.
