Type locality

GREECE • 1- Euboea, Delphi .

Description

SHELL. Very strong, well-spaced and whitish ribs becoming weaker and less spaced on body whorl. Moderately developed lip with abrubtly inwardly curved columellar lobe presumably covering umbilicus.

MEASUREMENTS. Based on MIZPASW7057: whorls= 7.3, H = 7.5 mm, H/W =2.69, roundness =0.14, ribs inclin.=59, ribs per mm 1 st whorl =12, ribs per mm 4 th whorl=9.

Remarks

We tentatively assign C. (T.) euboicum to the subgenus Turritus based on the shell morphology of the specimen in A.J. Wagner’s collection. Wagner (1897: 46–47) classified this species as part of the “Formenkreis Difficilis ”, with C. (T.) patulum and C. (T.) gracile (on the label of the specimen, however, it is classified as a subspecies of C. (T.) sturanii ).
