periphery sharply angled. Sculpture consisting of exceedingly fine 

 and dense growth-lines and distinct microscopic spiral lirae on the base. 

 Colour corneous, with irregular brown streaks on the upper surface, 

 but forming rather regular, broad, zigzag lines on the base. Spire 

 depressed, broadly convex, its height less than that of the aperture. 

 Protoconch flattish, of 1^ smooth volutions. Whorls 4J-, regularly 

 increasing, flatly convex, the last rather high in proportion ; periphery 

 sharply angled, base convex, a little depressed in the centre. Suture 

 not much impressed, simple. Aperture oblique, transverse, lunate. 

 Peristome thin and sharp, outer lip angled. Columella subvertical, 

 short, arcuate ; inner lip reflexed above and almost completely closing 

 up the very narrow perforation. Diam. 3*2, height 2 mm. 



Sab. — Waitakerei Range, North Island (H. S.). 



Its nearest congener, L. Ariel, has distinct radial riblets and the 

 spire much more elevated. Type in my collection.

Shell minute, depressed, globose, sub-perforate, corneous, very thin, 

 translucent, lightly shining, smooth. Sculpture microscopic, the 

 post-nuclear whorls with fine oblique growth-striae, reticulated by 

 distinct fine spiral lines. Colour corneous, with a greenish liue. Spire 

 depressed, conoidal, its height a little less than that of the aperture ; 

 outlines almost straight. Protoconch of 14- convex whorls, smooth. 

 Whorls 4, regularly increasing, convex ; periphery rounded, lightly 

 sub-angled, base convex, impressed at the middle. Suture rather 

 deep. Aperture obliciue, broadly rotundly lunate. Peristome simple, 

 sharp and thin, regularly arched. Columella short, arcuate ; inner lip 

 reflexed above, and almost completely closing the narrow perforation.

Sah. — Capleston, near Reef ton, South Island. Type in my collection. 



TOENATELLINA SUBPEKFORATA, n.Sp. PL XI, Fig. 30. 



Shell very small, conoidal, sub-perforate, thin, pellucid, shining, 

 light corneous. The only sculpture consists of fine oblique growth- 

 lines. Colour very light horny. Epidermis very thin, light brown, 

 very easily rubbed off. Spire elevated conic, a little higher than the 

 aperture. Protoconch globose. Whorls 5, convex, the last rapidly 

 increasing, ventricose ; base rounded. Suture impressed, faintly and 

 narrowly margined. Aperture subvertical, ovate, angled above. 

 Peristome thin, sharp ; outer lip moderately convex, basal lip narrower, 

 arched. Columella vertical, not twisted ; inner lip thin, broadly 

 reflexed above, and partly concealing the very narrow and not deep 

 perforation. Parietal wall with an entering median small lamella.

Hab. — Whangarei Heads; type (Mr. C. Cooper). Near Auckland 

 (H. S.). Raoul Island, Kermadec Islands (Miss Shakespear). 



The inflated body-whorl, the straight, not tortuous columella, and 

 the narrow perforation separate it at once from T. Nbvoseelandica, Pfr.
