(Figs 15, 17) but in some specimens this is much fainter (Fig. 14); body whorl with ± 28 ribs viewed from the front and the three above with 18-21 ribs; umbilicus deep. Aperture squarish pyriform; a curved parietal lamella near the right hand side; a prominent outer tooth, the rounded apex of which is close to the parietal lamella and cuts off a prominent upper sinus about a third the length of the aperture. At the back of the aperture a sloping arcuate lamella well away from the peristome corresponds to a deep furrow on the outside of the shell (Fig. 16); the outside area behind the peristome is closely ribbed, the ribs crossing and forming small arcs within the furrow; columella sloping, bearing a low protuberance or platform and either typically devoid of other dentition or with two interior small nodules between the base of the columella and the internal lamella. Dimensions: height 1.9-2.2 mm, breadth 0.6-0.7 mm. Distribution - Tanzania, Meru. Note - The dentition varies amongst the material; HNHM 93980/2 and 93981/5 (partly) have two small additional nodules at the base of the columella; HNHM 93978, HNHM 93979/16, HNHM 93880/4 and HNHM 93981/5 (partly) have no additional nodules. Gulella hildae VAN BRÜGGEN, 2001 (Figs 18-19)) Gulella hildae VAN BRÜGGEN, 2001 in Basteria 65: 102, fig. 1-3: type locality: S. MALAWI: Mt. Mulanje (RMNH 83932). Distribution - Malawi, Tanzania. Material examined - Tanzania, 20 km from Arusha, Meru S slope, Usa River settlement, in side of brook (1200 m), IV. 1979, leg. EŐRY & SIPOS (HMNH 92528/1); same locality, 27.111.1979, EŐRY & SIPOS (HMNH 92341/3) (occurring with Thapsia sp. and Afroguppya rumrutiensis (PRESTON, 1911). Remarks - At first I could not identify this small species until I went through recent papers by VAN BRÜGGEN and discovered he had described what was clearly the same species from a single specimen from Malawi. He informed me (in litt.) that PETER TATTERSFIELD had also found it in Tanzania. The specimens collected by EŐRY and SlPOS antedate these by some years and they must take credit for first discovering this species. Gulella afrooccidentalis sp. n. (Fig. 20) Type material - Holotype: Congo (Zaire), Kindamba, 4°43'S 13°03'E, Meya Village (not traced), 8.XI.1963, leg. J. BALOGH & A. ZlCSl (HNHM 93986).
