1. CYLINDROVERTILLA KINGI (Cox). The shell is sinistral, rimate, ovate, between cinnamon and fawn color. Surface glossy, very closely, minutely striate, the striæ oblique, very low, usually most distinct on the penult whorl, partly effaced or in part replaced by irregular granulation on the last. The apex is obtuse. Whorls are rather strongly convex, the last having a wide or strong, rounded, striate crest behind the outer and basal lips, of a dull orange-cinnamon color; behind the crest it is somewhat flattened laterally, convex below the suture. The aperture is somewhat oblique, shortly piriform, the peristome expanded, heavily thickened within by an orange-cinnamon or paler callous ridge. The angular lamella is strong, white, its emerging outer end low, curving to join (or nearly join) the termination of the outer lip. Columellar lamella white, rather small and short, almost tuberculiform. The upper palatal fold is short, not emerging to the callous rib. Lower palatal fold smaller and a little deeper within. Length 1.95, diam. 1.1 mm.; 5 whorls. Australia, New South Wales: Paramatta (R. L. King, type loc.), Vancluse Point, Port Jackson (C.
