elevated radial ribbing'. Ape.x typical of the hiiUu style, finely punctate, adult 
sculpture of rough ra dials, cut by coneenti'ie lines forming a subnodulose 
sculpture, the concentric lines disappearing on the base of the last whorl. 
Height 17 mm., breadth 11 mm. 
Mr. E. Sedgwick, who colled ed this interesting form at Hangeenan via

appear to be bearing fringes, but these are absent in the adult.
