Type locality The Marquese Marianna Paulucci , in the original description of the species, mentioned several localities: “ Abita le Alpi Apuane , il Monte Forato, la foce del Lucese, Prana e Gabberi, Ponte Stazzemese in provincia di Lucca...”. By the designation of MZUF 13605_10158 as lectotype , ITALY 1- Foce del Lucese ; 43.9354° N , 10.3821° E , becomes the type locality . Fig. 57. Lectotype (here designated) of Cochlostoma ( T. ) elongatum ( Paulucci, 1879 ) , 1- Foce del Lucese, I (MZUF-13605_100158). Description SHELL . Barely visible riblets on last part of protonch. Teleoconch with two lines of reddish spots on whorls. Ribs strong, more or less whitish and quite irregular in strength, becoming weaker toward aperture. Rather weak lip with gently inwardly curved columellar lobe covering umbilicus. MEASUREMENTS . 11 ♀♀ : whorls= 7.5–8.6, H = 7.2–8.9 mm , H/W=2.4–2.8, roundness= 0.14–0.21, ribs incl.= 57.9–71.5°, apert. incl.= 16.1–28.8°, ribs/mm 1 st wh.= 6–23, ribs/mm 4 th wh.=8–21. Fig. 58.

Elongated, club-shaped and more or less tortuous seminal receptacle with bent apex. 2–4 loops clustered close to apex of seminal receptacle. Junction of uterus gland far from connection of distal oviduct with pedunculus of bursa copulatrix. Remarks Due to the high conchological variability observed among the populations inhabiting the relatively small area of the Apuane, it seems useful to designate a lectotype and a unique type locality.
