The shell, which is strong and has a somewhat oval form, 



that is acuminated above, and rotundately tapers below, is 



of a rather glossy pale lilac red, or of a livid pinkish flesh 



colour ; the whorls are very narrowly edged with white 



beneath the suture. Of the two whitish or pallid fillets, 



that are usually present on the body of our native examples 



(though the anterior one is occasionally obsolete, and both 



are absent in a rare Mediterranean variety), and which 



vary as to width (yet are never very broad) in difl:eront 



individuals, the upper which is more frequently (yet not 



always) the narrower, and is often continued on the base 



of the smaller turns, runs in a line with the top of the 



aperture; the lower revolves halfway between the superior 



one and the anterior extremity. The entire exterior is 



striated in a spiral direction : the strise, which are very 



fine and densely disposed upon the middle of the shell, but 



at the lower end, where their intervals are raised in a 



somewhat costellar fashion, dilate into more distant sulci, 



are often rendered tremulous bv the wrinkles of increase,
