Cryptaulax bittneri

Gastropoda - Cryptaulacidae

Taxonomy
Promathildia bittneri was named by Kittl (1894) [Promathildia Bittneri]. Its type specimen is NHMW 1899/VII/40, a shell, and it is a 3D body fossil. Its type locality is St. Cassian (Klipstein coll), which is in a Julian carbonate limestone in the Cassian Formation of Italy.

It was recombined as Cryptaulax bittneri by Nützel (2002).

Diagnosis
ReferenceDiagnosis
A. Nützel 2002Teleoconch fragment of 5.5 whorls, 13 mm high, 5.3 mm wide, high-spired, slender; whorl profile straight but with incised sutures; ornament of about 10 straight, broad, rounded axial ribs per whorl and four broad rounded spiral cords (spiral I to 4) with additional second order spiral threads in interspaces; intersections of axial ribs and main spiral cords form broad spirally elongated knobs; adapical main spiral (spiral l) and third spiral most pronounced and of equal strength, spiral 2 and spiral 4 weaker, of about equal strength; spiral l located well below adapical suture, interspace between suture and spiral 1 contains at least three second order spiral threads; spiral 1 and spiral 2 relatively close to each other with one second order spiral thread between them; spirals 2, 3, and 4 have about the same distance of separation; spiral 4 immediately above lower suture, not as nodular as other main spirals; interspace between spiral 2 and spiral 3 with up to two second order spiral threads; interspace between spiral 3 and spiral 4 with two second order spiral threads; base rounded, moderately convex, with at least six spiral threads that are not or only slightly nodular; aperture and protoconch not preserved.
