Remarks: The new subspecies is distinguished from the rass-group of septemspirale by its slender tower-like whorl and rather narrow basic part ((Figure 12 shows the scatter diagramme of С septemspirale septemspirale — C. s. heydenianum — C. s. riedeli ssp. n. in function of breadth and height). The new subspecies occurs in the eastern frontier zone of Montenegro, south-east to the distribution of C' septemspirale bosniense (Boettger). The examined materials from Bosnia and Montenegro (Figures 4—9 and 10—11) are equal in forms with the original materials from Nemila (A. J. WAGNER, 1897, Taf. II. Fig. 27), the new subspecies is distinguished from the nominate form by the coneshaped shell and the larger mouth. A rather slender specimen from Bosnia (Zenica) is mentioned by WAGNER, 1906: 101 ,,. . .(auffallend schlanke, im Habitus an P. scalarinus VILLA erinnerende Form)." The specimen (shown in 1906. Taff. IL, Figure 3.) is similar to riedeli ssp. п., but in maesurement «(height 6.9 mm, breadth 3.07 mm) it is close to bosniense (Figure 12. ,,W" in white ring). The mouth of the rass-group of C. scalarinum (A. et J. B. VILLA) •expands like a trombone in front of the mouth-edge in profile, while the rassgroup of septemspirale has a puffed mouth.
