Differs from the preceding in being much smaller, having regular and thick 
ribs provided with a minute sutural spine. D’Orbigny indicates the color as 
“rosea.” It looks like a diminutive Scala Loveni, Me. Andrew.

approximate, interstitiis levissimis, interdum lirula intercalante; costa xii interdum xvi in

sata duplice, peristomate continuo.

richt, ibid. 1842).

I refer my specimens to the species of D’Orbigny, although the author indicates 
the number of ribs in the last whorl as 20-25, which does not agree with the 
figure. Of six specimens, only one has sixteen ribs. The measure of D’Orbigny 
indicates too a very small individual. ‘Scala gréulandica, Perry, gives a good idea 
of this little shell.
