with an A:B ratio of 1.3:1. Uterus gland strongly developed with a slit-like opening into mantle cavity at rectum. Fig. 87 illustrates the body of a female specimen. Male reproductive system (Figs 7883). Prostrate opening into mantle cavity at rectum on posterior end of animal. Prostrate and penis connected via a long tube. Penis large, widest at beginning of its free section, evenly tapered towards apex. Length-width ratios 6.8:1, 7:1, 10:1 (Figs 78-80), and 5.9:1 and 6:1 in immature specimens (Figs 80-84). Vas deferens linear inside penis. Development of penis, as in majority of Cochlostoma taxa, coinciding with thickening of apertural lip. In Figs 81-82 lip thin and translucent, but callous in Fig, 83. Figs 85-86: C. auritum méridionale (Boettger) (85= female genitalia; 86= body of female) Cochlostoma auritum méridionale (O. Boettger 1886) Material: southern Montenegro, valley at Stari Bar, near Bar, 7 00-800 m, macchia on limestone, coll. A. Wiktor, 30-31.10.1982 (Figs 85-86). Only a single specimen was examined. The female reproductive system (Fig. 85) exhibits no substantial dissimilarities from the nominal form, the only difference being the changed A:B ratio of the sac of bursa copulatrix. Fig. 86 shown the body of this specimen. REFERENCES GIUSTI, F. (19/71): Primo contributo alia revisione del genere Cochlostoma Jan e descrizione di Toffolettia n. gen.
