"This new subspecies constitutes the third known Cerion from the Bimini Islands. It differs from both C. pillsburyi Pilsbry and Vanatta and C. biminiense Henderson and Clapp by being nearly smooth, these latter two species being strongly costate on all whorls other than the nuclear whorls. It also differs from both of these species by being strongly mottled with brown, C. pillsburyi being nearly white with but a faint brownish tinge, while C. biminiense is almost a uniform brownish.
In relationship C. eximium lerneri is very close to typical C. eximium Maynard from Eleuthera and Cat Island, differing mainly in the extent of the mottled coloration and in not having the backward extension of the lip as pronounced as it is in the typical form.
We also have a lot similar to this form from Paradise Point, North Bimini Island.
A statistical analysis of biometric data will be published by Mayr and Rosen." (Clench, 1956:2-3)
