Diagnosis
ReferenceDiagnosis
R. L. Squires 1984Bucciniform shell with two spiral ribs on spire and about six spiral ribs on body whorl, interspaces char- acteristically concave with numerous fine lirae. Due to the fact that the canal area has been broken off on each of the Llajas specimens, positive generic assignment cannot be made.
Ancistrolepis? carolineae n. sp. is very similar to A. clarki Tegland (1933: 131-132, pl. 12, fig. 14) and A. clarki variety? Tegland (1933:132, pl. 12, figs. 15-17) from the Oligocene Blakeley Formation, northwestern Washington. A.? caroli- neae differs from A. clarki and A. clarki var.? in the following features: less convex whorls, narrower and shorter spire, equally spaced primary spiral ribs on the spire, less inflated spiral ribs, and smaller shell size. Unfortunately, the anterior canal area is missing in the Llajas specimens and comparison to the ornamented canal areas of A. clarki and A. clarki var.? cannot be made. A. clarki and A. clarki var.? differ from each other only in the nature of the canal area ornamentation.
