Gulella eoryi sp. n. (Figs 14-17) Type material - Holotype: Tanzania, Meru Crater. S side, above Usa River, observation tower no. 17, rocks, 28.111.1979, leg. EŐRY & SlPOS (HNHM 93978). Paratypes: same date and locality as holotype (HNHM 93979/16); Tanzania. Meru. S slope, above Usa River, Hunter's House (2000 m). IV. 1979. leg. EŐRY & SlPOS (HNHM 93981/5); same locality, moss forest. 30.111.1979. leg. EŐRY & SIPOS (HNHM 93980/2); Meru Crater, S side, above Usa River. "Átnyergelő rét" (1700 m). 30.IV. 1979. leg. EŐRY & SlPOS (HNHM 93880/4). Diagnosis - No related species has been found; the partial furrow on the body whorl might suggest a relationship with Ptychotrema L. PFEIFFER, 1853, but I do not think this is so. Description - Shell very small, elongate, fusiform-cylindrical, slightly tapering (Figs 14-15, 17); apex rounded, smooth; whorls 6 when viewed from front, actually 7, the four main whorls with strongly crenulate sutures, the crenae typically passing into quite strong ribbing across the whorls Figs 17-20. 17 = Gulella eoryi sp. n. paratype (identical with holotype). 18 = G. hildae VAN BRÜGGEN, 2001, 19 = same, oblique view of sinus of aperture showing side of parietal lamella. 20 = G. afrooccidentalis sp. n. holotype (scale bar = 1 mm)
