_whorls, a little thickened, most so in the middle ; their interstices are 
crossed by several distinct spiral cinguli, which also render the ribs 
a little nodulous ; on the penultimate whorl there are about five cin- 
guli; on the last whorl a strong, round, spiral carina surrounds the 
base or umbilical region, starting from under the upper margin of the 
outer lip and inclosing a space on which two or more faint spiral 
grooves can be detected. Aperture round; lips continuous; mar- 
gin of outer lip thickened by a rib; inner lip with the edge reflected 
in the umbilical region; no umbilicus. Color white.

* For those malacologists who adopt the ancient generic names of Klein (1756), as 
was done by Messrs. H. and A. Adams, Scala K1. displaces Scalaria Lam. In that 
case, following the Adamsian nomenclature, the preceding species would be named as 
follows: Scala Pourtalesii; Scala Dalliana; Scala (Opalia) Andrewsti; Cirsotrema 
Leeana.
