We do not feel assured that this is the species intended 

 by PhiHppi, but are contented to abide by the supposed 

 identification in default of evidence to the contrary. The 

 British shell is very slenderly subulate, rather thin, slightly 

 translucent, of an uniform polished white, and smooth to 

 the eye ; yet under a powerful lens most densely disposed 

 microscopic spiral striula may occasionally be perceived, 

 and obsolete irregular longitudinal wrinkles are dimly ap- 

 parent. The spire, which is nearly four times as long as 

 the body, and slowly tapers to a tolerably fine exserted 

 apex, is composed of about seven volutions (besides the 

 heterostrophe apical coil) which are of decidedly slow lon- 

 gitudinal increase, and of moderate height (that is to say, 

 in the jienult turn the breadth does not exceed the length 

 by much more than one-half the latter) ; they overlap each 

 other rather broadly and shelve from top to bottom in a 

 gently convex line, yet usually incline inwards a little at 

 their base. The suture is profound, and a little slanting. 

 The basal declination of the body, which occupies only a 

 fifth of the entire length, is moderately rounded, and is 

 neither abrupt nor at all angulated at the commencement. 

 The aperture, which is throughout devoid of sculpture.
