Weak, longitudinal ribs undulate the central whorls and appear on the last whorl, but vanish there before reaching the periphery. The columella lip is broad and reflected, obliquely

The larger whorls are closely corded by spiral lyrse, having smaller lyrse in their interstices. Weak, longitudinal ribs undulate the central whorls and appear on the last whorl, but vanish there before reaching the periphery. The columella lip is broad and reflected, obliquely ridged within and sharply bent above. The aperture is perpendicular, ovate and grooved within. Rissoa joviana of Melvill and Standen* appears to me to be an absolute synonym of Alaba fulva, Watson, f These and Alaba striata, Watson\ should enter the same genus as pyrrhacme. Indeed I am not satisfied that all four names do not apply to aspects of one polymorphic species. SCALA REVOLUTA, sp. nOV. (Pig. 7). Shell minute, white, with smooth coiled apex and variced, solute, subsequent whorls. Whorls six, of which the apical three are smooth and in contact, the fourth commences to uncoil and the remainder are widely separate. Varices eight on the last whorl, with an anterior corner, slightly elevated ; between the varices the shell is smooth and glossy. Aperture broken in the type example, but apparently circular. Length 3, breadth 1 -5 mm. One specimen from the lagoon beach. The only shell for which the novelty might be mistaken is S. hyalina, Sowerby. Judging from Sowerby's drawing^ that differs by being much larger, broader, uncoiled to the tip, though less apart latterly, and by more numerous and serrate varices. Scala paumotensis, Pease. Tryon, Man. Conch, ix., 1887, p. 65, pi. xiii., fig. 1G. Four specimens from the lagoon beach. Cited by Tryon from Fiji, Gilberts, and Paumotus. Scala subauriculata, Souverbie.
