1 80 TORN ATELLIN A , 



38. T. IREDALEI P. & C., 11. sp. PL 39, figs. 6, 7, 8. 



The shell is imperf orate, oblong-conic, the diameter about 

 half the length, cinnamon-brown, slightly transparent. Out- 

 lines of the spire straight. Whorls 5%, moderately convex. 

 Parietal lamella not large, nearly a half-whorl long. Colu- 

 inella weakly sigmoid, the columellar margin slightly convex 

 but not angular in profile view. Length 2.9, diam. 1.5, aper- 

 ture 1.1 mm.

 deposited in the Canterbury Museum, N. Z. ; paratype in coll. 

 A. N. S. P. 



The columella is distinctly less sinuous than in T. novosee- 

 landica. T. petterdi, master si and noumeensis are decidedly 

 stouter in figure. 



The paraneanic stage, 2.4 to 2.5 mm. long, is like the adult 

 in apertural characters. No younger examples were in the lot 

 submitted by Mr. Iredale, after whom the species is named. 



This may be the species which has been recorded as T. 

 novoseelandica from the Kermadecs. See Iredale, Proc. Malac. 

 Soc. London, x, 1913, pp. 364, 365. 



39. T. RAOULENSIS P. & 0., ii. sp. PL 39, figs. 9, 10, 11. 



The shell is imperforate, oblong-conic, the diameter slightly 

 more than half the length, buffy-olive, nearly smooth. Whorls 

 6, rather strongly convex, united by a rather deep suture, 

 which appears nearly horizontal. Aperture more than one- 

 third the length of shell. Parietal lamella very oblique, 

 rather high but short, about one-third of a whorl long. Colu- 

 mella having a low, wide, spiral prominence in the middle, 

 terminating in a strong, projecting angle, prominently seen 

 in a profile view (fig. 9). Length 3.3, diam. 1.7, aperture 

 1.3 nun.

This is a larger, more robust species than T. iredalei, with 

 the parietal lamella more oblique, shorter, and the columellar 

 fold ending in a projecting point, as in Lamellina and the
