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, Reeve, but it is certainly 
not the ophelia of Pfeiffer. It is common in limestone districts in the South 
Island. 
THERASIA VALERIA, n.8. Pl. ix., fig. N. H. hypopolia, Hutton, Trans. 
N.Z. Inst., vol. xiv. (1881), p. 151, pl. 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 (F. W. H.). 
| Differs from T. thaisa in the narrow umbilicus, and from 7’, ophelia in 
being ribbed. | 
TrocHOMORPHA (?) HERMIA, n. $. 
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 rugosely plicated above; smooth and polished 
below; both surfaces with rather distant spiral strie; 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 strie on 
the upper surface, not so well marked on the under surface ; strie about 
seven, principal strie 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.
