Cerion hatoensis H.B Baker, 1924
"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 (C11d) as the type locality."
