| In 1959 the first author (A.C.v.B.) discovered a peculiar snail of the pulmonate family Endodontidae in Rhodesia; on a subsequent expedition more specimens were obtained, so that a series is now available for description. The species undoubtedly belongs to the genus Trachycystis Pilsbry, 1893, but a new subgenus has to be created in order to accomodate this particular species. Anatomical data and figures have been supplied by the second author (B.V.), while the first author is responsible for the remaining part of text and figures. Dendrotrichia subgen. nov. A subgenus of Trachycystis characterised by ramose bristles on the surface of the shell; genital anatomy like that of subgenus Chalcocystis. Type species: Trachycystis (Dendrotrichia) sylvicola spec.... |

| The following notes mostly concern the description of new species from East Africa in connection with renewed work on a check-list of the non-marine Mollusca of that area which has been in preparation during the past 25 years. A fairly complete manuscript has been available for many years but additional material and further research continually render it in need of revision. Previous notes in this series were published in Basteria, the last being Verdcourt (1978). A number of the professional photos have been kindly made by Mr. A. 't Hooft of the Department of Systematics and Evolutionary Biology of the University, Leiden; Dr. A. C. van Bruggen of the same university department has made the paper ready for the press. The following abbreviations are used in... |
