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.

 approximatse, intei'stitiis laevissimis, interdum lirula intercalante ; costse xii interdum xvi in 

 anfr. ult., crassiusculse, ssepe duplicatae, continuee, siinplices. Apertura ovalis, labio iucras- 

 sata duplies, peristomate continuo.

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 gronlandica, Perry, gives a good idea 



of this little shell.
