Distribution - Tanzania, Mt. Meru. Material examined- Tanzania, Meru, above Usa River, Crater, S side, "Átnyergelő rét" (1700 m), 30.IV. 1979, leg. EŐRY & SlPOS (HNHM 92335/1). Meru ML, III. 1962, leg. SÁSKA (HNHM 92437/1). Meru, 1970, collector not known, (HNHM 92446/1). Gulella peakei VAN BRÜGGEN, 1975 (Fig. 8) Gulella peakei VAN BRÜGGEN, 1975 in Bulletin of the British Museum (Natural History), Zoology 28: 164, fig. 2; type locality: Aldabra Island: Middle Island (He Malabar) (BMNH GG21 202). Distribution - Aldabra Island, Kenya and Tanzania. Material examined - Tanzania, Meru S slope, Usa River settlement, 20 km from Arusha ( 1200 m) (in side of brook), III-IV.1979 leg. EŐRY & SlPOS (HNHM 93863/4 and HNHM 93864/15). Remarks - There is no doubt that the two shells from Usa River belong to Gulella peakei and that they are closer to subspecies peakei than they are to G. p. continentalis later described by VAN BRÜGGEN (1975) from South Africa. The aperture is more quadrangular than in material from the type locality but without Figs 7-10. 7 = Gulella ingloria (PRESTON, 1913), 8 = G. peakei VAN BRÜGGEN, 1975, 9 = G. kimbozae sp. n., holotype, 10 = same, twisted to show inner side of aperture wall (scale bar = 1 mm)
