but constricted near the base and with a point, the outer cusp very oblique, 

 notched at the end. Marginals broad, rounded at the ends, with numerous 

 points, the inner one of which is much longer than the rest. 



Hab. Waiau, Southland (G. M. Thomson). 



This species is, I think, the same as H. ophelia, Eeeve, but it is certainly 

 not the ophelia of Pfeiffer. It is common in limestone districts in the South 

 Island. 



Therasia Valeria, n.s. PI. is..-, fig. n. H. hypopolia, Hutton, Trans. 

 N.Z. Inst., vol. xiv. (1881), p. 151, pi. iii., fig. b, not of Pfeiffer. 



Shell globoso-conoidal, depressed, finely ribbed, subperforate ; colour 

 •pale horny, irregularly marked with rufous. Spire conoidal, obtuse ; peri- 

 phery obtusely angled ; suture scarcely impressed ; whorls 4-5, rather flat- 

 tened, irregularly finely ribbed both above and below, ribs about 20-25 in 

 the tenth of an inch ; umbilicus very narrow, covered ; aperture oblique, 

 angularly lunate; peristome simple, the margins not converging; colu- 

 mellar margin reflected. Greatest diameter -25, least -2; height -15 

 inch. 



Hab. Dunedin (P. W. H.). 



Differs from T. ■ thaisa in the narrow umbilicus, and from T. ophelia in 

 being ribbed. 



TrOCHOJIORPHA (?) HERMIA, n. S. 



Shell conical, depressed, imperforate, striated; colour horny brown, 

 paler above than below, columella white. Spire conical depressed, obtuse ; 

 periphery acutely angled ; suture slightly gradated or margined; whorls 5, 

 flattened, closely obliquely rugoseiy plicated above ; smooth and polished 

 below ; both surfaces with rather distant spiral striae ; base of the shell 

 round the umbilical region slightly impressed; aperture very oblique, 

 angularly lunate ; peristome thin, the margins not approaching ; the 

 columella callous. Greatest diameter -7, least -6 ; height -4 inch. 



Hab. Manawatu (T. W. Kirk). 



The generic position is doubtful. 



Cyclotus charmian, n.s. 



Shell rather thin, depressed, widely umbilicated, spirally striated; colour 

 pale brown. Spire convex, obtuse ; periphery with an undulating keel ; 

 suture impressed ; whorls 4, rounded, with distant spiral raised striae on 

 the upper surface, not so well marked on the under surface ; striae about 

 seven, principal striae on the upper surface, with smaller ones between 

 them; last whorl rounded at the mouth, keeled further back; umbilicus 

 wide, not keeled, showing all the whorls ; aperture oblique, circular, the 

 interior callous ; peristome simple, thin, straight, the two margins united 

 by a thin callus. Greatest diameter -4, least -32 ; height -22 inch.
