Cerion kralendijki H.B.Baker, 1924
"Cerion uva bonairensis, new subspecies
Type locality: (B5) Porta Spaño, Bonaire.
Distribution: Bonaire; everywhere on limestone (B1 to B9), and in the richer habitats on the older rocks (Bb3, 7, 9). Klein-Bonaire: everywhere (K1). 343 adults collected.
In this subspecies (Plate XXI), as in arubanum, the palatal wall of the peristome projects out markedly from the preceding whorls. However, the aperture is usually broader, instead of twisted tangentially, so that the umbilicus is smaller, and more like that of the typical subspecies. Also, C. uva bonairensis (Table XIV) has high whorls similar to knipensis, and the cleaned surface of the shell resembles dead-white enamel while that of the other species is chalky-white or porcellanous. As in the subspecies from Curaçao, the Bonaire lots vary in size with the richness of the locality. Typical bonairensis (fig. xxi-F6) includes the larger shells of the series, while the smaller lots may be called form kralendijki, new (fig. xxi-A2), with the recent limestone just south of Kralendijk (Bl) as the type locality; Although the cerions of Bonaire invade the central regions of older rocks to a considerable extent, the form desculptum appears to be quite absent."
