Diagnosis
Reference | Diagnosis | |
---|---|---|
K. V. Palmer 1937 | Shell large; ventricose; .characters typical of Cyprcedia; surface of the shell completely covered with fine, equal, distinct, transverse ribs with an occasional, microscopic, interculated line; the transverse ribs cut finer, longitudinal lines which give the surface an obscure, cancellated appearance; along the entire length of the columella and outer lip are large, transverse folds; on the columella there is a ridge over which the plaits are slightly protruding, they decrease in size and become continuous with the ribs over the shell; the plaits on the inner margin on the outer lip decrease in size and also become continuous with the body ribs; some of the transverse ribs which begin along the outer margin of the outer lip, appear to be due to divarication; others are of a distinct, separate origin. |
