Cerion bequaerti de la Torre and Clench, 1932
"CERION AGUAYOI BEQUAERTI, subsp. nov. Plate 6, fig. 8.
This subspecies differs from the typical form in being larger, more cylindrical and the spire more tapering. In the specimens examined by us there is no indication of the "wide point" which occurs just above the middle in both C. proteus and C. aguayoi. The locality of C. aguayoi bequaerti is about 50 Km. east of Gibara, the locality of the other forms.

Holotype: M. C. Z. No. 86177, dunes at Lucrecia lighthouse, near Banes, Oriente, Cuba. Paratypes: M. C. Z. No. 86176.
This subspecies is probably a direct offshoot of C. proteus stock and apparently may be a form of parallel development similar to that of C. aguayoi. However, it seems best in our present understanding of these forms to consider it a subspecies of the latter species to which it more closely approximates."
