. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. New Cryptella from the Canary Islands 345. 2 mm Fig. 7: Cryptella famarae n. sp.; shell in dorsal, ventral and lateral view. Shell: Large shell with a large protoconch (length x width in the type series: 5, 24 ± 0, 29 X 3, 32 ± 0, 19, n = 9; for further measurements see Hutterer 1990: Tab. 1, sample "Lanzarote sub f."). The nucleus of the latter is clearly visible, as the suture stays nearly uncalcified. The aperture of the protoconch is small, nearly round, its columellar margin with a significant callus. In lateral view the angle between aper- tural margin and spathula is approximately 110 to 120° (Fig. 7). Ecology: Cryptella famarae was found only at the ridge and in the steep slopes of the Famara CHffs in the north of Lanzarote. The few specimens found alive by A. Machado on 12 May 1986 were feeding on leaves of Reichardia famarae. Fresh shells were found in May 1990 at the bottom of almost vertical rocky cliffs entirely covered by lichens. The Famara Cliffs are famous for their rich vegetation (Kunkel 1982); they form a relict habitat for numerous plants and animals dependent on permanent moisture. In May 1991 subfossil shells of Cryptella were found at three localities of Graciosa, which represent the first record of the genus for this island. The materials probably date from the Pleistocene and Holocene. The shells agree very well with shells of the living C. famarae from Lanzarote and we conclude that they represent the same species which, however, does no longer occur in Graciosa. The island is very arid to- day, and humid cliffs such as in Famara are no longer present. Comparisons: C. famarae differs from the other species of which the anatomy is known (see figures in Groh et al. 1991; the unique holotype of the extinct C. tamaranensis [Hutterer, 1990] was not dissected) by the reproductive system, jaw, spermatophore,
