both species mentioned when the name was first proposed appear to be Lunatias; though species belonging to Ampullina seem to have been included later.” Key to Species. fyfei: large (38 mm. high), oval; low spire, sinuous inner margin. firmus: moderate size (about 20 mm. high), ovate; umbilicus slightly overlain by inner lip. lateapertus: moderate size (about 20 mm. high), globose; suture impressed or channelled, umbilicus very wide. vitreus: spire moderate. outlines regular; umbilicus small, circular, almost closed in young; lip retracted to suture. pseudovitreus: spire variable, generally high, spire-whorls strongly convex; lip not retracted to suture. pukeuriensis: suture impressed. barrierensis: flattened shape, low spire, very wide umbilicus. Uber (Euspira) fyfei n. sp. (Plate 59, figs. 8, 9.) Shell large, oval; spire low, gradate; whorls 6, convex on spire, body-whorl increasing rapidly, extended somewhat anteriorly; surface with growth-lines; suture deeply impressed; aperture large, ovate, channelled posteriorly; outer lip almost straight, with slight posterior sinus ante-current to suture; inner lip sinuous; parietal wall with thin enamel layer not straightening contour of inner lip; umbilicus open, of moderate size, without funicle or bounding-limb. Type in collection of Mr. H. J. Finlay. Height, 38 mm.; diameter, 35 mm. Localities.—Boulder Hill; Wangaloa;? Hampden (a crushed specimen in which the outer lip is slightly retracted to the suture and which may be a distinct species). Because of its low spire, this shell somewhat resembles N. suteri, but several important characters show that it is but distantly related thereto. These are the sinuous inner margin of the aperture, impressed suture, absence of any trace of a funicle or circum-umbilical limb, and strongly antecurrent outer lip. The salient characters are reminiscent of Hedley's genus Friginatica, members of which are all very small, and with rather elevated spires, but with a sunken suture, and “without an umbilical funicle or a callus pad at the insertion of the right lip.” Uber (Euspira) firmus n. sp. (Plate 59, figs. 2, 3.) Shell of moderate size, globose-ovate, solid; spire one-half the height of aperture or less; whorls about 5, convex on spire, body-whorl globular; suture abutting, sometimes tangential; aperture semilunar; outer lip straight, retracted to suture, inclined about 35° from vertical; inner lip slightly concave, with thin parietal callus contracting suddenly to inner margin; umbilicus moderate to fairly large, open, without funicle. Type in collection of Mr. H. J. Finlay. Height, 24 mm.; diameter, 21 mm. Localities.—Boulder Hill (type); 887a, Wangaloa (= P. amphialis of Suter, 1921, p. 97); 480, “Island sandstone,” overlying coal-beds, Waihao River (= P. huttoni and P. amphialis of Suter, 1921, p. 65). Uber (Euspira) lateapertus n. sp. (Plate 59, figs. 4, 5, 6.) Shell of moderate size, globose; spire gradate, about one-third the height of aperture; whorls 5, convex on spire; suture deeply impressed,
