Cerion diablensis H.B. Baker, 1924

Original Description

"Typical C. uva uva probably comes from the hills behind Willemstad. This lot (Table XI) happens to give a mean size and the mean number of whorls near those of all of the lots taken together. Although the change in form, due to the num­ber of whorls and the resultant difference in altitude, is very conspicuous (Plate XVIII), it is too variable to be of any racial importance; in fact, aperture formation appears to be hastened by injury. The actual size of the shells seems more important, and the extreme lots deserve recognition as ecologi­cal forms. The most dwarfed shells may be called form diablensis, new (fig. xviii-A2), with the top of Ronde Klip (C12b) as the type locality. The largest shells also have the heaviest sculpture, and may be included in the form hatoensis, new (fig. xviii-F6), with the eastern escarpment of Seroe Spelonk, near Landhuis Rato (Clld) as the type locality." (H. B. Baker, 1924:100).
