CYLINDROVERTILLA FABREANA Shell umbilicate, sinistral, subovate-oblong, thin, trans- lucid, scarcely shining, corneous. Spire moderately elevated, the apex obtuse. Suture lightly impressed. Whorls 5, convex, regularly increasing, the last shorter than the spire (1), strongly scrobiculate or pitted outside where the outer passes into the basal margin. Aperture subvertical, semioval, contracted by three folds colored like the shell: first a strong parietal, second marginal [palatal], deeply placed, third columellar. Peristome narrowly expanded, a little thickened, corneous-whitish, the basal margin thickened within at the place of the external pit, the outer margin somewhat inflexed in the middle. Length 1.5, diam. 1.3 mm. (Crosse). New Caledonia: Vata, near Noumea (E. Marie). Australia Boyne Island, Queensland (Musson).

Vertigo fabreana CROSSE, Journ. de Conch., xlii, 1894, p. 304 (1896). - - A species very close to Pupa paitensis, which is also sinistral, but to be distinguished as follows: the shell is umbilicate, not perforate-rimate, oblong rather than ventricose, a little more glossy, the spire less conic, whorls 5 instead of 412, the last smaller than the spire and externally having two pits, the aperture with three teeth instead of one (Crosse). The larger angular and upper-palatal folds and especially the thickening of the callus within the basal lip characterize this species, of which topotypes from Marie and G. Dupuy have been examined. The original figure of Crosse is copied in fig. 5. The shell is chamois-colored, weakly, faintly striate, with traces of fine malleation on the last whorl. Behind the lip there is a rather deep, wide impression or pit over the upper palatal fold, the whorl swollen above and below it, and on the base there is another impression close behind the lip. The aperture is small, oblique. The expanded peristome has a heavy internal callus, narrow in the sinulus, an obtuse inward projection below it; and in the base the callus rises in a low, wide boss. The angular lamella is very long and somewhat sinuous. Columellar lamella rounded. Upper palatal fold rather long, higher and bent down within, weakly emerging to the lip-callus. There is no lower palatal fold. Length 1.75, diam. 0.85 mm.; 41 whorls. Anse Vata. Length 1.63 mm. Length 1.8 mm. A series of this species was collected on Boyne Island, southeastern Queensland, by C. T. Musson. The specimens, or some of them, show a trifle more striation than those of New Caledonia, and the angular lamella may be slightly more sinuous; but the differences noted are trivial. An average example and one somewhat stouter and more distinctly striate are figured. They measure: Length 1.65, diam. 0.84 mm. Fig. 12. Length 1.63, diam. 0.9 mm.
